GENERAL DESCRIPTION
If a request is made through Modbus and later another one with the remote control, the Modbus will
indicate the color set through Modbus, it is because the unidirectionality between Modbus module
and the Lumiplus modulator controlled trough remote control.
When a simultaneous request is made through Modbus and remote control, and there is no conflict,
the last request will take effect.
In general, there is not check on the constancy of the values sent to specific registers. Therefore is the
operator responsibility to check that consistency.
In this manual, the numbers in hexadecimal have been represented with the format
0xZZ
, where ZZ is
the number.
The register map that governs the7.2 State Machine Diagram and all that is explained below is in the
chapter 9 Basic Modbus-RTU register map.
