Environmental Monitoring Probe (FC 03 or 04)
The optional Environmental Monitoring Probe for the PDU/RPP can
measure temperature and humidity. Because the device can be located
outside the PDU/RPP, the reference is to “auxiliary” data. In addition, it
contains two connections for monitoring the condition of auxiliary input
contacts, such as a door switch. See Table 9 for a list of EMP registers.
An exception code is returned if the EMP is not installed.
To read the temperature at the PDU/RPP, set the Modbus program to
Unit ID 254 and coil address 12028:
IP: <IP address of PDU/RPP>
Unit ID: 254
Starting Register: 12028
Number of registers: 2
Function Code: 04
