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 C. 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 system manual 135U/155U /2/.
• • Link to the PG via SINEC H1/L2/L1 and "swing cable"; the
COR C or PG multiplexer can be connected in the link.
