13.3.1 Setting and Reading the Time in the
Programmable Controller
The CP 5430 TF/CP 5431 FMS has the job number 218 available for
processing the time.
A SEND with this job number writes the CP’s time, a RECEIVE, reads the
CP’s time.
These services are possible on the synchronized CP interfaces using the
standard HDBs for the PLC.
☞
When the CP starts up, internal test functions can lead to a
waiting time of 1 second before the clock can be read out
reliably from the PLC.
To provide the time for the programmable controller, the following
representation is used:
