●
Set the simulation mode for DIs with register 40281
Bit 0 to bit 9 of register 40281 can be used to set the simulation mode for DI1 to DI 10.
For example, if you want to simulate DI1 with Modbus, you need to set bit 0 = 1 for
register 40281.
●
Set the setpoint for DIs with register 40283
Bit 0 to bit 9 of register 40283 can be used to set the setpoint for the simulated DI signals.
After the DI simulation mode is set, you can set the setpoint for a DI signal with register
40283 to enable the DI signal. For example, if you have set bit 0 = 1 for register 40281, to
enable signal DI1, you need to set the trigger condition (rising edge or high level) for bit 0
of register 40283.
