9.6 User Modbus
This function is available to BaseBox controller with standard FW v 3.0 and higher.
User Modbus function allows users to assign up to 127 registers from range 42873 to 43000 to any value or
setpoint available for Modbus reading or writing in the controller. This can be used for standardizing the Modbus
communication or for quick batch reading or writing (note that it is possible to write no more than 16 registers in
on multiple writing request).
It is not possible to read or write both standard registers and User Modbus registers in one request (e.g. batch
reading of registers 42998 to 43007 is not possible). It is perfectly fine to separate the request and read User
Modbus registers and standard registers individually.
