TOPIC: TeslaScada with remote DIO

Can I know how to configure a remote DIO (Modbus RTU) for the TeslaScada? I connected the remote DIO to com port 1 of the TeslaScada. It have 3 relay output and is use to activate external buzzer if there is alarm event in HMI. I set the remote DIO to modbus rtu, address = 3.

I set the com port 1 in BIOS as below,

serial port configuration from RS232 to RS485
COM1 R1 setting from R1 to 12V

In TeslaScada I added in a new server named tP3R3.

In project file on alarm tag I assigned the output to 'PV Output server: tP3R3', slaveID = 3 (same as DIO address)

Then I make the alarm on HMI and it is ok in TeslaScada but not signal to operate the remote DIO relay to activate buzzer.

Hello,

Check your register addresses. SlaveID is not enough to setup output register of Modbus devices.
It's not necessary to setup Output server for communication with output register, you also can Input server and setup Input register if it's the like output for the Tag.
