Performance

Event

This is the time between the occurrence of an event (for example rising edge on an

processing time:

EVT input of the module 1, presetting on a counting channel of the TSX 37-22 base

SRT

or of a TSX CTZ module, etc.) and the assignment of a discrete output.

SRT = 1.5 ms (SRT = Software Response Time)

Note: Inputs 0 to 3 of module 1 should be configured with a minimum filtering value,

so that they can be used in EVT inputs.

Cycle time for an application.

To calculate the overall cycle time of a discrete application, the following must be

added:

the system overhead corresponding to the type of PLC,

the program execution time for the number of kilo instructions,

the acquisition time for the discrete inputs,

the update time for the discrete outputs.

For details of all these times, refer to (Reference manual PL7, volume 3,

performances).

Note: To find out the true current duration of an application, with the help of the

debug processor screen, you must subtract from the displayed value a value of 2

ms, corresponding to the time taken by the PLC to process information requested

by the console or the network module.

The maximum duration indicated in this screen can have a high value, if a PCMCIA

format communication module is present in the PLC.

Protection treatment for TSX 37 Micro PLCs

General points

TSX 37 PLCs meet all "TC" treatment requirements (1).

For installations in industrial production workshops or in an atmosphere

corresponding to "TH" treatment (2), TSX 37 PLCs must be embedded in IP54

minimal protection envelopes as recommended in standards IEC 60664 and NF C

20 040.

The TSX 37 PLCs themselves display an IP20 protection index (3).

They can therefore be installed without an envelope in restricted access locations

not exceeding pollution degree 2 (control rooms containing no dust-producing

machines or activities).

(1) "TC" treatment: treatment for all climates.

(2) "TH" treatment: treatment for warm and humid atmospheres.

(3) In the event that position is not occupied by a module, a TSX RKA 01 protection

cover needs to be mounted.

Rules of installation

PLC

Certain rules must be respected for installing containers and inserting modules

arrangement

during the mounting of the TSX 37 PLCs:

The PLCs should be air-cooled by natural convection. To facilitate their

ventilation, they should be installed vertically with the ventilation louvers on the

top. Only the horizontal position is therefore authorized.

If several PLCs are installed in the same rack, it is recommended that the

following provisions be respected:

leave a space of at least 150 mm between two overlapped PLCs, to allow a

passage for the wiring ducts and to facilitate air circulation,

it is advised to install heat generating devices (transformers, supply modules,

power switches, etc) above the PLCs,

leave a space of at least 100mm at each side of a PLC (with or without

extension) to allow a passage for the wiring and to facilitate air circulation,

if the internal RAM memory is backed up by a battery (optional), it will be

necessary to provide sufficient space (>= 50 mm) between the PLC and the

duct, in order to allow the hatch to be opened and access to the battery.

PLC mounting/fixing

General

The TSX 37 PLCs, with or without mini extension rack can be mounted on a DIN

profile, a Telequick board or on a panel:

the process of fixing onto a DIN profile requires no accessories,

the process of fixing onto a Telequick board or on a panel is performed by 4

screws with a diameter of M4 for the base and 2 screws with a diameter of M4 for

the mini extension rack, these 6 screws are not supplied. If mounting is difficult,

from a mechanical point of view, it is preferable to fix the PLC onto a board or

panel.

The installation rules (See Rules of installation, p. 98) are to be respected, whatever

the type of mounting.

Ground connection of the PLC

General

Grounding the TSX 37 bases and mini extension rack is provided by the rear

section, which is metallic. This guarantees efficient working order for PLCs in

environment norms, on condition however that they be fixed on a correctly grounded

metal support. The base and extension should be mounted on the same support or

supports, which are correctly coupled together.

To ensure personal safety, it is always necessary to ground the base ground

connection terminals and the mini extension rack.

For this, use a 2,5 mm² (minimum) green/yellow wire of the shortest length possible.

Grounding the modules

General

Grounding the modules is performed with a contact on the back (2 contacts for the

modules in standard format), which connects to a metallic finger forming a part of

the PLC base or mini extension rack when inserted into a module. This connection

ensures grounding.

Supply connections

Introduction

The TSX 37 range offers two possibilities for the supply of PLCs:

alternating current,

and direct current.

The PLC is

the base delivers the 24 VDC (24 VR) voltage necessary to supply the coils of its

integrated relay modules,

alternating

however, the mini extension rack must be supplied with 24 VDC in the following

current

cases:

analog modules are positioned in the extension,

relay modules are positioned in the extension, The 24 VDC supply tolerance

must be +/- 10% max. If this voltage disappears or there is a reduction of more

than 10%, good working order of the relay modules is no longer ensured. No

error indication is given to the application program. If detection of this error is

desired, you are advised, for example, to use a dividing bridge inline with an

analog input of the base configuration.

Note: When the PLC is supplied with alternating current, it is strictly forbidden to

use the 24 V sensor voltage, provided by the base, to supply the mini extension

rack with 24 VDC (24 VR).

between 19 and 30 VDC (and up to 34 VDC for 1 hour for a battery operated

device with charger).

However, if relay modules are fitted to the PLC (base or extension), the 24 VDC

supply should have a maximum tolerance of +/- 10%.

A TSX SUP supply can be used to provide the 24 VDC voltage (refer to wiring

diagrams on the following pages).

Connection

Connection rules

General

The TSX 37 PLC supply terminal block is protected by a door, which allows access

to the wiring terminals. Wire output passes vertically to the bottom. Wiring can be

maintained in position by a cable tightening clip.

Note: Plan for a device, which protects and cuts the supply upstream of the PLC.

When the PLC is supplied by a direct network, the length of the supply cable must

be limited to 30 m if the wires have a cross section of 2.5 mm² or 20 m if the wires

have a cross section of 1.5 mm², to prevent a loss of line.
