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 supported:

Commands

Read binary input values

Write binary output values

Read analog input values

Write analog output values

Read diagnostic data

Return query data

The following table shows in which registers the UMC100.3 data and diagnosis can be accessed:

—

Analog inputs of UMC100.3 acc. to the UMC100.3 manual section

A1 parameters and data structures on a Fieldbus

Data

0x0200
