This example shows a PLC-PLC connection between two S5-95Q program-
mable controllers. It is a bidirectional PLC-PLC connection.
From each programmable controller (station 11 and station 12), the value of
IB 33 is sent with a positive-going edge at I 32.0 to the partner PLC and indi-
cated there with QB 32.
Shown in Figure H-1 is the configuration for a PLC-PLC connection.
