Telecontrol communication (CP 1542SP-1 IRC)
4.5.1
Configuration
Data points for telecontrol communication
No program blocks need to be programmed for the CP 1542SP-1 IRC to transfer user data
between the station and communications partner.
The data areas in the memory of the CPU intended for communication with the partner are
configured data point-related on the CP. Each data point is linked to a PLC tag or element in
a data block on the CPU.
The individual data points can be transferred to the control system and processed there.
To transfer the process data and for some options of the parameter groups "Partner stations"
and "Communication with the CPU" configured data points are required.
For further information, refer to section Data point configuration (Page 57).
