Use Modbus RTU/ASCII with control modules to write in digital output
registers
Once a digital output module is set up with a control module, it will automatically
assign the digital output modules’ output records registers at the address of 0x2000
Example:
Two digital output module registers will at 0x2000 and 0x2001
※
When using control modules, RS485 can connect to control modules with 0170-
0101.
The configuration that uses Modbus RTU/ASCII with a control module to write in
digital output modules is listed below:
