Modbus Communication And Register Map For Umc100.3 - ABB MRP31.0 Technical Description

Modbus communication and Register Map for UMC100.3

Devices on a Modbus network offer their data in registers to a Modbus master. There is the possibility to read or write single bits
(coils) or whole words.(registers).
The following Modbus requests are generally supported:
Commands
Read binary input values
Write binary output values
Read analog input values
Write analog output values
Read diagnostic data
The following table shows in which registers the UMC100.3 data and diagnosis can be accessed:
