What are the Modbus register addresses of the Zelio Logic communications module SR3MBU01BD?

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.
