Maintenance and Troubleshooting
CPU Indicators
The DL105 Micro PLCs have indicators on the
front to help you diagnose problems with the
system. In normal runtime operation only the RUN
and PWR indicators are on. The table below is a
quick reference to potential problems.
Indicator Status Potential Problems
Run, Power, CPU
PWR (LED off)
1. System voltage incorrect
Indicators
2. PLC power supply faulty
RUN (LED off)
1. CPU programming error
2. (CPU in program mode)
CPU (LED on)
1. Electrical noise interference
2. Internal CPU defective
PWR Indicator
In general there are three reasons for the CPU power status LED (PWR) to be OFF:
1. Power to the unit is incorrect or is not applied.
2. PLC power supply is faulty.
3. Other component(s) have the power supply shut down.
If the voltage to the power supply is not correct, the PLC may not operate properly or
may not operate at all. Use the following guidelines to correct the problem.
WARNING: To minimize the risk of electrical shock, always disconnect the system
power before inspecting the physical wiring.
1. First, disconnect the external power.
2. Verify that all external circuit breakers or fuses are still intact.
3. Check all incoming wiring for loose connections. If you’re using a separate
termination block, check those connections for accuracy and integrity.
4. If the connections are acceptable, reconnect the system power and verify
the voltage at the DL105 power input is within specification. If the voltage is
not correct shut down the system and correct the problem.
5. If all wiring is connected correctly and the incoming power is within the
specifications, the PLC internal supply may be faulty.
The best way to check for a faulty PLC is to substitute a known good one to see if this
corrects the problem. The removable connectors on the DL105 make this relatively
easy. If there has been a major power surge, it is possible the PLC internal power
supply has been damaged. If you suspect this is the cause of the power supply
damage, consider installing an AC line conditioner to attenuate damaging voltage
spikes in the future.

Maintenance and Troubleshooting
RUN Indicator
If the CPU will not enter the Run mode (the RUN indicator is off), the problem is
usually in the application program, unless the CPU has a fatal error. If a fatal error
has occurred, the CPU LED should be on. (You can use a programming device to
determine the cause of the error.)
Both of the programming devices, Handheld Programmer and DirectSOFT32, will
return an error message describing the problem. Depending on the error, there may
also be an AUX function you can use to help diagnose the problem. The most
common programming error is “Missing END Statement”. All application programs
require an END statement for proper termination. A complete list of error codes can
be found in Appendix B.
If the CPU indicator is on, a fatal error has occurred in the CPU. Generally, this is not
CPU Indicator
a programming problem but an actual hardware failure. You can power cycle the
system to clear the error. If the error clears, you should monitor the system and
determine what caused the problem. You will find this problem is sometimes caused
by high frequency electrical noise introduced into the CPU from an outside source.
Check your system grounding and install electrical noise filters if the grounding is
suspected. If power cycling the system does not reset the error, or if the problem
returns, you should replace the CPU.
Communications Problems
If you cannot establish communications with the CPU, check these items.
S The cable is disconnected.
S The cable has a broken wire or has been wired incorrectly.
S The cable is improperly terminated or grounded.
S The device connected is not operating at the correct baud rate (9600
baud).
S The device connected to the port is sending data incorrectly.
S A grounding difference exists between the two devices.
S Electrical noise is causing intermittent errors.
S The PLC has a bad communication port and should be replaced.
For problems in communicating with DirectSOFT32 on a personal computer, refer
to the DirectSOFT32 manual. It includes a troubleshooting section that can help you
diagnose PC problems in communications port setup, address or interrupt conflicts,
etc.

Maintenance and Troubleshooting
I/O Point Troubleshooting
Possible Causes
If you suspect an I/O error, there are several things that could be causing the
problem.
S High-Speed I/O configuration error
S A blown fuse in your machine or panel (the DL105 does not have
internal I/O fuses)
S A loose terminal block
S The auxiliary 24 VDC supply has failed
S The Input or Output Circuit has failed
Some Quick Steps
When troubleshooting the DL105 Micro PLCs there are a few facts you should be
aware of. These facts may assist you in quickly correcting an I/O problem.
S
HSIO configuration errors are commonly mistaken for I/O point failure
during program development. If the I/O point in question is in X0-X3, or
Y0-Y2, check all parameter locations listed in Chapter 3 that apply to
the HSIO mode you have selected.
S
The output circuits cannot detect shorted or open output points. If you
suspect one or more faulty points, measure the voltage drop from the
common to the suspect point. Remember when using a Digital Volt
Meter, leakage current from an output device such as a triac or a
transistor must be considered. A point which is off may appear to be on
if no load is connected the point.
S
The I/O point status indicators are logic-side indicators. This means the
LED which indicates the on or off status reflects the status of the point
with respect to the CPU. On an output point the status indicators could
be operating normally while the actual output device (transistor, triac
etc.) could be damaged. With an input point, if the indicator LED is on
the input circuitry is probably operating properly. Verify the LED goes off
when the input signal is removed.
S
Leakage current can be a problem when connecting field devices to an
I/O point. False input signals can be generated when the leakage
current of an output device is great enough to turn on the connected
input device. To correct this install a resistor in parallel with the input or
output of the circuit. The value of this resistor will depend on the amount
of leakage current and the voltage applied but usually a 10K to 20KW
resistor will work. Verify the wattage rating of the resistor is correct for
your application.
S
Because of the removable terminal blocks on the DL105, the easiest
method to determine if an I/O circuit has failed is to replace the unit if
you have a spare. However, if you suspect a field device is defective,
that device may cause the same failure in the replacement PLC as well.
As a point of caution, you may want to check devices or power supplies
connected to the failed I/O circuit before replacing the unit with a spare.

Noise Troubleshooting
Electrical Noise
Noise is one of the most difficult problems to diagnose. Electrical noise can enter a
Problems
system in many different ways and they fall into one of two categories, conducted or
radiated. It may be difficult to determine how the noise is entering the system but the
corrective actions for either of the types of noise problems are similar.
S Conducted noise is when the electrical interference is introduced into
the system by way of a attached wire, panel connection ,etc. It may
enter through an I/O circuit, a power supply connection, the
communication ground connection, or the chassis ground connection.
S Radiated noise is when the electrical interference is introduced into the
system without a direct electrical connection, much in the same manner
as radio waves.
Reducing
While electrical noise cannot be eliminated it can be reduced to a level that will not
Electrical Noise
affect the system.
S Most noise problems result from improper grounding of the system. A
good earth ground can be the single most effective way to correct noise
problems. If a ground is not available, install a ground rod as close to
the system as possible. Ensure all ground wires are single point
grounds and are not daisy chained from one device to another. Ground
metal enclosures around the system. A loose wire can act as a large
antenna, introducing noise into the system. Therefore, tighten all
connections in your system. Loose ground wires are more susceptible to
noise than the other wires in your system. Review Chapter 2 Installation,
Wiring, and Specifications if you have questions regarding how to
ground your system.
S Electrical noise can enter the system through the power source for the
PLC and I/O circuits. Installing an isolation transformer for all AC
sources can correct this problem. DC sources should be well-grounded
good quality supplies.
S Separate input wiring from output wiring. Never run low-voltage I/O
wiring close to high voltage wiring.

Machine Startup and Program Troubleshooting
The DL105 Micro PLCs provide several features that can help you debug your
program before and during machine startup. This section discusses the following
topics which can be very helpful.
S Program Syntax Check
S Duplicate Reference Check
S Special Instructions
S Run Time Edits
S Forcing I/O Points
Syntax Check
Even though the Handheld Programmer and DirectSOFT32 provide error checking
during program entry, you may want to check a program that has been modified.
Both programming devices offer a way to check the program syntax. For example,
you can use AUX 21, CHECK PROGRAM to check the program syntax from a
Handheld Programmer, or you can use the PLC Diagnostics menu option within
DirectSOFT32. This check will find a wide variety of programming errors. The
following example shows how to use the syntax check with a Handheld Programmer.

There are several instructions that can be used to help you debug your program
Instructions
during machine startup operations.
S END
S PAUSE
S STOP
END Instruction: If you need a way to quickly disable part of the program, just insert
an END statement prior to the portion that should be disabled. When the CPU
encounters the END statement, it assumes that is the end of the program. The
following diagram shows an example.

PAUSE Instruction: This instruction provides a quick way to allow the inputs (or
other logic) to operate while disabling selected outputs. The output image register is
still updated, but the output circuits are not. For example, you could make this
conditional by adding an input contact or CR to control the instruction with a switch or
a programming device. Or, you could just add the instruction without any conditions
so the selected outputs would be disabled at all times.

STOP Instruction: Sometimes during machine startup you need a way to quickly
turn off all the outputs and return to Program Mode. You can use the STOP
instruction. When this instruction is executed the CPU automatically exits Run Mode
and enters Program Mode. Remember, all outputs are turned off during Program
Mode. The following diagram shows an example of a condition that returns the CPU
to Program Mode.

Maintenance and Troubleshooting
Run Time Edits
The DL105 Micro PLC allows you to make changes to the application program
during Run Mode. These edits are not
“bumpless.” Instead, CPU scan is
momentarily interrupted (and the outputs are maintained in their current state) until
the program change is complete. This means if the output is off, it will remain off until
the program change is complete. If the output is on, it will remain on.
WARNING: Only authorized personnel fully familiar with all aspects of the
application should make changes to the program. Changes during Run Mode
become effective immediately. Make sure you thoroughly consider the impact of any
changes to minimize the risk of personal injury or damage to equipment. There are
some important operational changes during Run Time Edits.
1. If there is a syntax error in the new instruction, the CPU will not enter the Run
Mode.
2. If you delete an output coil reference and the output was on at the time, the output
will remain on until it is forced off with a programming device.
3. Input point changes are not acknowledged during Run Time Edits. So, if you’re
using a high-speed operation and a critical input comes on, the CPU may not see
the change.
Not all instructions can be edited during a Run Time Edit session. The following list
shows the instructions that can be edited.

Forcing I/O Points
There are many times, especially during machine startup and troubleshooting, that
you need the capability to force an I/O point to be either on or off. Before you use a
programming device to force any data type it is important you understand how the
DL105 CPUs process the forcing requests.
WARNING: Only authorized personnel fully familiar with the application should
make program changes. Do thoroughly consider the impact of any changes to
minimize the risk of personal injury or damage to equipment.
Bit Forcing — Bit forcing temporarily changes the status of a discrete bit. For
example, you may want to force an input on even though the program has turned it
off. This allows you to change the point status stored in the image register. The
forced value will be valid until the CPU writes to the image register location during the
next scan. This is useful you just need to force a bit on to trigger another event.
The following diagrams show a brief

You can access the AUX Functions from DirectSOFT32 or from the D2-HPP
Handheld Programmer. The manuals for those products provide step-by-step
procedures for accessing the AUX Functions. Some of these AUX Functions are
designed specifically for the Handheld Programmer setup, so they will not be
needed (or available) with the DirectSOFT32 package. Even though this Appendix
provides many examples of how the AUX functions operate, you should supplement
this information with the documentation for your choice of programming device.
Note, the Handheld Programmer may have additional AUX functions that are not
supported with the DL105 PLCs.

AUX 2* — RLL Operations
RLL Operations auxiliary functions allow you to perform various operations on the
ladder program.
AUX 21
Both the Handheld and DirectSOFT32 automatically check for errors during
Check Program
program entry. However, there may be occasions when you want to check a program
that has already been in the CPU. Two types of checks are available:
S Syntax
S Duplicate References
The Syntax check will find a wide variety of programming errors, such as missing
END statements. If you perform this check and get an error, see Appendix B for a
complete listing of programming error codes. Correct the problem and then continue
running the Syntax check until the message “NO SYNTAX ERROR appears.
Use the Duplicate Reference check to verify you have not used the same output coil
reference more than once. Note, this AUX function will also find the same outputs
even if they have been used with the OROUT instruction, which is perfectly
acceptable.
This AUX function is available on the PLC Diagnostics sub-menu from within
DirectSOFT32.
AUX 22
There will probably be times when you need to change an I/O address reference or
Change Reference
control relay reference. AUX 22 allows you to quickly and easily change all
occurrences, (within an address range), of a specific instruction. For example, you
can replace every instance of X5 with X10.
AUX 23
There have been many times when we’ve taken existing programs and added or
Clear Ladder
removed certain portions to solve new application problems. By using AUX 23 you

can select and delete a portion of the program. DirectSOFT32 does not have a
menu option for this AUX function, but you can just select the appropriate portion of
the program and cut it with the editing tools.
AUX 24
AUX 24 clears the entire program from CPU memory. Before you enter a new

EEPROM in the Handheld Programmer. (Note, you cannot have multiple programs
Name
stored on the EEPROM.) The program name can be up to eight characters in length
and can use any of the available characters (A-Z, 0-9). AUX 51 allows you to enter a
program name. You can also perform this operation from within DirectSOFT32 by
using the PLC/Setup sub-menu. Once you’ve entered a program name, you can
only clear the name by using AUX 54 to reset the system memory. Make sure you
understand the possible effects of AUX 54 before you use it!
AUX 53
AUX 53 displays the current, minimum, and maximum scan times. The minimum
Display Scan Time
and maximum times are the ones that have occurred since the last Program Mode to
Run Mode transition. You can also perform this operation from within DirectSOFT32
by using the PLC/Diagnostics sub-menu.
AUX 54
The CPU maintains system parameters in a memory area often referred to as the
Initialize
“scratchpad”. In some cases, you may make changes to the system setup that will be
Scratchpad
stored in system memory. For example, if you specify a range of Control Relays
(CRs) as retentive, these changes are stored.
NOTE: You may never have to use this feature unless you have made changes that
affect system memory. Usually, you’ll only need to initialize the system memory if you
are changing programs and the old program required a special system setup. You
can usually change from program to program without ever initializing system
memory.
AUX 54 resets the system memory to the default values. You can also perform this
operation from within DirectSOFT32 by using the PLC/Setup sub-menu.
AUX 55
DL105 PLCs have a “watchdog” timer that is used to monitor the scan time. The
Set Watchdog
default value set from the factory is 200 ms. If the scan time exceeds the watchdog
Timer
time limit, the CPU automatically leaves RUN mode and enters PGM mode. The
Handheld displays the following message E003 S/W TIMEOUT when the scan
overrun occurs.
Use AUX 55 to increase or decrease the watchdog timer value. You can also perform
this operation from within DirectSOFT32 by using the PLC/Setup sub-menu.
AUX 57
DL105 CPUs provide certain ranges of retentive memory by default. Some of the
Set Retentive
retentive memory locations are backed up by a super-capacitor, and others are in
Ranges
non-volatile EEPROM. The EEPROM memory locations are V4000 to 4177, and
V7630 to V7647. The default ranges are suitable for many applications, but you can
change them if your application requires additional retentive ranges or no retentive
ranges at all (see Appendix E).

WARNING: The DL105 CPUs do not have battery-backed RAM. The
super-capacitor will retain the values in the event of a power loss, but only up to 3
weeks. (The retention time may be as short as 4 1/2 days in 60 degree C operating
temperature.)
AUX 58
AUX 58 is used to override the output disable function of the Pause instruction. Use
Test Operations
AUX 58 to program a single output or a range of outputs which will operate normally
even when those points are within the scope of the pause instruction.
AUX 5B
AUX 5B is used with the High-Speed I/O (HSIO) function to select the configuration.
Counter Interface
You can choose the type of counter, set the counter parameters, etc. See Chapter 3
Configuration
for a complete description of how to select the various counter features.
AUX 6* — Handheld Programmer Configuration
The following auxiliary functions allow you to setup, view, or change the Handheld
Programmer configuration.
AUX 61
As with most industrial control products, there are cases when additional features
Show Revision
and enhancements are made. Sometimes these new features only work with certain
Numbers
releases of firmware. By using AUX 61 you can quickly view the CPU and Handheld
Programmer firmware revision numbers. This information (for the CPU) is also
available from within DirectSOFT32 from the PLC/Diagnostics sub-menu.
AUX 62
The Handheld has a beeper that provides confirmation of keystrokes. You can use
Beeper On / Off
Auxiliary (AUX) Function 62 to turn off the beeper.

Auxiliary Functions
AUX 8* — Password Operations
There are several AUX functions available that you can use to modify or enable the
CPU password. You can use these features during on-line communications with the
CPU, or, you can also use them with an EEPROM installed in the Handheld
Programmer during off-line operation. This will allow you to develop a program in the
Handheld Programmer and include password protection.
S AUX 81 — Modify Password
S AUX 82 — Unlock CPU
S AUX 83 — Lock CPU
AUX 81
You can use AUX 81 to provide an extra measure of protection by entering a
Modify Password
password that prevents unauthorized machine operations. The password must be
an eight-character numeric (0-9) code. Once you’ve entered a password, you can
remove it by entering all zeros (00000000). (This is the default from the factory.)
Once you’ve entered a password, you can lock the CPU against access. There are
two ways to lock the CPU with the Handheld Programmer.
S The CPU is always locked after a power cycle (if a password is present).
S You can use AUX 82 and AUX 83 to lock and unlock the CPU.
You can also enter or modify a password from within DirectSOFT32 by using the
PLC/Password sub-menu. This feature works slightly differently in DirectSOFT32.
Once you’ve entered a password, the CPU is automatically locked when you exit the
software package. It will also be locked if the CPU is power cycled.
WARNING: Make sure you remember the password before you lock the CPU. Once
the CPU is locked you cannot view, change, or erase the password. If you do not
remember the password, you have to return the CPU to the factory for password
removal.
NOTE: The DL105 CPUs support multi-level password protection of the ladder
program. This allows password protection while not locking the communication port
to an operator interface. The multi-level password can be invoked by creating a
password with an upper case “A” followed by seven numeric characters (e.g.
A1234567).
AUX 82
AUX 82 can be used to unlock a CPU that has been password protected.
Unlock CPU
DirectSOFT32 will automatically ask you to enter the password if you attempt to
communicate with a CPU that contains a password.
AUX 83
AUX 83 can be used to lock a CPU that contains a password. Once the CPU is
Lock CPU
locked, you will have to enter a password to gain access. Remember, this is not
necessary with DirectSOFT32 since the CPU is automatically locked whenever you
exit the software package.

Special Relays
DL105 PLC Special Relays
“Special Relays” are just contacts that are set by the CPU operating system to
indicate a particular system event has occurred. These contacts are available for
use in your ladder program. Knowing just the right special relay contact to use for a
particular situation can save lot of programming time. Since the CPU operating
system sets and clears special relay contacts, the ladder program only has to use
them as inputs in ladder logic.
