Values
To modify Coil Status and Holding Register values at the RTU by sending controls from the
master station, select the “Copy Control Output Value to Input” feature from the Modbus tab in
the Properties menu. Writing “O󰀨” to a coil causes ‘0’ to be written to the Input Coil; “On” is ‘1’.
To invert this interpretation, select the “Invert Trip/Close Value” check box.
When enabled, states written to output coil index ‘n’ will cause a change in the state of input coil
‘n’, and similarly for writes to Output registers and values of Holding Registers.
