The SR3MBU01BD is a communication module for the Zelio Smart Relay SR3 (24Vdc) that allows the Zelio to be used in a Modbus Serial Network:
Zelio SR3 will be slave in the network so a Master is needed.
The input register addresses are %MW16 - %MW19 but are only available in FBD, not Ladder.
The output register addresses are %MW20 - %MW23.
The Zelio clock can be interrogated using registers %MW32 - %MW35.
The attached file gives more detailed information.
If you need a Master in the Modbus Serial network then the best solution will be to use a PLC like the Modicon M221.
