7.3 Example of a Program for an S5-S5 Link
The aim of the example is to set up a communication system that allows
simple control of the activity on a SINEC L2 bus system. It should be
possible to formulate the basic information required to set up and operate a
SINEC L2 bus system and to control the activity on the bus system. The
example illustrates how to program the CPU and assign parameters for the
CP as well as triggering and checking the data transmission.
You should have worked through Chapters 3 to 6 of this manual and be
familiar with the handling blocks and STEP 5.
