7.6.1 Requesting the measuring value of all channels of an RCMS470-12
The actual measuring values of all 12 channels of an RCMS470-12 with address 12 are to be interro-
gated.
For that purpose the PROFIBUS-Master at first interrogates channel 1 (output data):
In return the RCMS470-12 sends a measuring value of 22 mA to channel 1 (input data):
Channel 2 is being requested (output data):
In return the RCMS470-12 sends a measuring value of 224 mA to channel (input data):
Channel 3 is being requested (output data):
In return the RCMS470-12 sends a measuring value of 8 A to channel 3 (input data):
Channel 4 is being requested(output data):
The RCMS470-12 replies that channel 4 has been switched off (input data):
Channel 4 is being requested (output data):
The RCMS470-12 replies that no current measuring transformer is connected to channel 5:
The channels 6 to 12 are to be requested consecutively, as shown in the example.
