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
Write binary output values
Read analog input values
Write analog output values
Read diagnostic data
Return query data n.a.
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
