7.3 Requesting the measuring values via channel number
The following examples only differ in their replies.
The PROFIBUS Master addresses BMS address 7, the RCMS470-12 residual current monitor, for infor-
mation about the actual measuring value. This value is available at channel 10.
PROFIBUS Master output data:
The RCMS470-12 replies that a fault current of 100 mA is the measuring value to channel 10.
PROFIBUS Master input data:
The PROFIBUS Master addresses BMS address 7, the RCMS470-12 residual current monitor, for infor-
mation about the actual measuring value. This value is available at channel 10.
PROFIBUS Master output data:
The RCMS470-12 signals a fault current of 9 A as the actual measuring value.
