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