4.2 Connecting a PLC to the PG
To be able to link up with a PLC, your PG must have an active
TTY port (20 mA).
If the COM 1 port available is a V.24 interface, the AG-S5
interface must be simulated by means of an S5 converter
The programmable controller (PLC) and the PG are connected via
a direct connection (4) or by two connecting cables. If the port
assignment described in section 4.4 is not used, the connections
will have to be adapted accordingly.
