Fig 11-10 shows a typical configuration for the multiprocessor mode.
No parameter assignment
for the CPU
No parameter assignment is necessary on the CPU 948 to use the PG
functions via the S5 bus.
Technical requirements
The PG functions via the S5 bus with the CPU 948 can only be used
when the PG and PLC are networked via SINEC H1.
You require the following:
•• a PG 7xx with SINEC-H1 connection and with STEP 5 software
version 6.3 (ST) or 6.0 (MT) installed with the delta diskette
CPU 948
•• in the PLC (central controller or expansion unit EU 185), a CP 143
communications processor from version 06 (firmware version 3.0)
upwards with the base interface number 232 selected (the base in-
terface number is set in the hardware using jumpers and in the SY-
SID using COM 143).
