2.10 Operating the Application
The following chapter describes the operation as well as the test and diagnostic
functions of the different scenarios.
Prerequisites
The SIMATIC S5-CPU program and the CP1430 TCP connection configuration
include all example scenarios. The required S5 program blocks and the
corresponding functions are enabled via enable bits after loading the S5 program.
For successfully testing a scenario,
• the corresponding enable bit in the SIMATIC S5-CPU must be set,
• the corresponding SIMATIC S7-1500 station must be loaded,
• the corresponding enable bit in the SIMATIC S7-CPU must be set where
necessary.
