11.5 PG Functions via the S5 Bus
11.5.1
Application
The PG functions via the S5 bus allow you to load and control
S5-155U programmable controllers with the CPU 948 connected via
SINEC H1 using the PG 7xx. With the PG functions via the S5 bus,
the CPU 948 can be loaded up to eight times faster than via the PG
interface. The actual speed depends on the length of the blocks to be
transferred.
You can also use the PG functions via the S5 bus in the multiprocessor
mode.
The PG functions via the S5 bus are a component of the system
program of the CPU 948.
Caution
The PG functions via the S5 bus can only be used alternately
with the PG functions via the first and second serial interface (i.e.
one function only at a time).With some functions,
(simultaneous/nested functions) data or blocks may be corrupted.
With the CPU 948 numbers > 232 are reserved for the PG
functions via the S5 bus. These numbers are not freely available
for handling blocks.!
