Hi,
I just want to verify a potential design we're considering when interfacing with a BMS system.
We will be using Vijeo/HMI to communicate with the electrical equipment but will also provide access to metering information via a switch to the BMS.
My question relates to the functionality of the PM8240 and whether it can be both a Modbus Master and Modbus Slave.
I found an FAQ that indicates that it can be configured as a Modbus Master to communicate with the PM5110 Modbus Slaves and if I use Unit ID 255, the Modbus Master (PM8240) will respond to those Modbus requests.
However, an online guide suggests that it can be a Modbus Master OR a Modbus Slave so just want to be sure that if I configure the network as follows (simplified), I can communicate with both the Modbus Master (PM8240) and Modbus Slaves (PM5110s) using Modbus only.
