Extending the Cycle Time

Note that the cycle time of a user program is extended by the following:

Time-controlled interrupt handling

Process interrupt handling (see also Section 7.3)

Diagnostics and error handling (see also Section 7.3)

Operating System Processing Time

The operating system processing time for the IM 151/CPU 

takes 540 

s to 1040 

s

(see Table 7-1).

The specified time does not include the execution of:

Test functions, e.g. monitor, modify

Functions: Load block, delete block, compress block

Communication

Process Image Transfer Time

The table below contains the CPU times for process image updating (process
image transfer time). The specified times are ”ideal” values that get increased by
interrupts that occur or by communication involving the CPU component of the
IM 151/CPU.

(Process image = PI)

The CPU time for process image updating is calculated as follows:

K + A = process image transfer time, in which K and A equal the following:
