PG Functions via the S5 Bus
Step
5
Load the parameter data on the CP 143:
The parameter data of the CP 143 can either be stored
-
in an EPROM cartridge
or
-
in the RAM of the CP 143.
You can transfer the parameter data via the serial interface of the PG 7xx.
The operations necessary for loading the parameter data of the CP 143 are described in /6/.
6
Perform an overall reset on the CPU, switch the power supply to the PLC off and on
again.
7
Edit the path to the CPU 948 in the bus selection screen form of STEP 5.
8
Select the path to the CPU 948 via SINEC H1/CP 143 in the presets screen form of
STEP 5.
Alternative operation via the
serial PG interface
Notes
11 - 32
Action
Once these actions have been performed, the PG functions can be used
via the S5 bus. You can now load your user program and run or test it.
At any one time, the CPU 948 only processes one PG function. If you
attempt to activate further PG functions on a second PG via the serial
PG interface while a PG function is already being processed, a
message, for example, "AS function disabled: function active" is
displayed on this PG.
If a PG function is aborted by switching the mode selector on the CPU
from RUN to STOP or by an error, wait times of greater than 15
seconds are activated for communication via SINEC H1.
If you make a mistake on the PG (e.g. switching off the PG with a PG
function still active) it is possible that the "selection" function must be
repeated when the path is re-established.
