Recommendations for Use with a High Communications
Load

Background

When using the CP described here, the points below will help you to avoid
overload situations on your CPU.

In particular when you replace an older CP with the CP described here and are
then confronted with overload problems, you should check your application for the
pitfalls outlined below.

Known Problems

The functions for sending and receiving (FC 5/FC6 or FC 50/60) are often

called cyclically in OB1. This leads to constant communication between the

CPU and CP. As a result, other types of communication such as PG functions

cannot be executed or only very slowly.

HMI systems access data of the CPU too often using S7 functions. This slows

down communication generally and can lead to lack of resources on the CPU if

SEND/RECEIVE FCs are called in OB1 cyclically (effect: reduced data

throughput or increased reaction time).

Remedy

The recommendations below will help to avoid these situations:

Do not call communication blocks cyclically in OB1!
Communication should be called time-controlled in a suitable cyclic-interrupt

OB. The call interval of this OB should be significantly higher than the average

cycle time of your program.

You should set a minimum cycle time that is higher than the average runtime of

OB1. This frees resources for communication on the CPU. This is, for example,

a remedy for existing applications when communication already takes place

cyclically in OB1.

If necessary, reduce the time taken for communication processing on the CPU

by changing the parameters set for “cyclic load due to communication” in the

properties dialog of the CPU.
