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

MODBUS Function Codes

Starting address

Read binary input values

FC 1 Read Coils
FC 2 Read Discrete Inputs

0000 Hex

Write binary output values

FC 15 Write Multiple Coils

0100 Hex

Read analog input values

FC 3 Read Holding Registers
FC 4 Read Input Registers

0200 Hex

Write analog output values

FC 16 Write Multiple Registers

0300 Hex

Read diagnostic data

FC 3 Read Holding Registers
FC 4 Read Input Registers

2000 Hex

Return query data

FC 8 Sub Function 00

n.a.

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