Solution
2.1
Overview of the general solution
The PSE_DIAG (FB50) block of library “SITOP_Library_V12_S7-300_S7-400”
reads the signal of the state output (S) of the PSE200U module via a digital input at
the S7-CPU and evaluates the read signal. The information available from the
evaluation is displayed as message on a SIMATIC Panel.
We will show you:
how the PSE_DIAG (FB50) block is integrated in the user program of the
S7-CPU
how the states of outputs OUT 1 to OUT 4 of the PSE200U module are
visualized on a SIMATIC Panel (TP900 Comfort Panel)
a message procedure (control messages (PLC alarms))
