11.4 Serial Link PG - PLC via 1st or 2nd Serial Interface

For the serial link PG - PLC there are the following possibilities:

•• Direct link to the CPU via the standard cable.

•• Link to the PG via the coordinator COR 923C. In this case the PG

is connected via the cable to the coordinator. This means that the

1st serial interface is no longer available.

•• Link to the PG via a PG multiplexer 757. The permitted cables can

be found in the S5-135U/155U System Manual (/2/ in Chapter 13).

•• Link to the PG via SINEC H1/L2/L1 and "swing cable"; the

COR 923C or PG multiplexer can be connected in the link.
