3.3.4.1
Devices with RS 485 interface
You can transmit the measured values of the energy meters via the RS 485 interface.
The device functions as a standard Modbus slave.
Serial communication is configured using setup parameters P-20 to P-24.
You can find the Modbus register tables in chapter Modbus address table for single-phase
devices with Modbus interface (Page 82).
Parameters P-02 to P-07 can be used to define the behavior of a programmable limit
threshold. Its status is transmitted.
The programmable limit threshold can be used, for example, to signal an alarm situation to a
remote device.
Activation of the programmable limit threshold is indicated on the display by the symbol.
Note
The status of the programmable limit threshold is not updated during parameterization
(setup).
3.3.4.2
Devices with M-Bus interface
Devices with an M-Bus interface support 2 addressing paths:
•
Primary address from 1 to 250
•
Secondary address from 00000000 to 99999999
Baud rates from 300 to 38400 bps
Parameters P-02 to P-07 can be used to define the behavior of a programmable limit
threshold. Its status is transmitted.
The programmable limit threshold can be used, for example, to signal an alarm situation to a
remote device.
Activation of the programmable limit threshold is indicated on the display by the symbol.
Note
The status of the programmable limit threshold is not updated during parameterization
(setup).
