Typical Execution Times for Release 3.0 CPUs

The following table details function block timing for Release 3.0, Micro PLCs.

For each instance of a function block, the table shows typical execution times when the
function block is enabled (receiving power flow) or disabled (not receiving power flow).

Typical Execution Times for Release 2.0 CPUs

The following table details function block timing for Release 2.0, Micro PLCs and Nano PLCs.
PLCs are grouped by similar types: Nano PLCs, 14/23/28 Point Micro PLCs, and 28-Point
Micro PLCS with ESCP.

For each instance of a function block, the table shows typical execution times when the
function block is enabled (receiving power flow) or disabled (not receiving power flow).

Typical Execution Times for Release 1.1 CPUs

Depending upon the application, release 1.1 CPUs show the following estimated
reductions in program execution times when compared with release 1.0 CPUs:

Nano PLCs: 20% - 28%

14-Pt Micro PLCs: 28%

28-Pt Micro PLCs: 28%

The following table details function block timing for a Release 1.1, 28-Point Micro PLC CPU
with  ESCP,  model  IC200UDD120.  For  each  instance  of  a  function  block,  the  table  shows
typical  execution  times  when  the  function  block  is  enabled  (receiving  power  flow)  or
disabled (not receiving power flow).
