How can I set two SV on ModBus?

[xinyuanTan]

I have 2 slave on the modbus and I want to controll them on the same time. But I can only fInd way to control one of them by write the slave number on PID block under. How can I controll another slave?

The slave is DTA4848

Not sure what you mean by control, but Artisan is only supporting one PID loop (either external or the internal Software PID). However, you can send any MODBUS command, also one that modifies the SV in any of your connected devices, via a custom event button or slider. Anything beyond this is rather special and it might be better to implement your own control software.

thank you! I add a slider to send MODBUS command write(1,18177,{}) ,that I can set two SV together
But I find there might a bug. the SV is the controlled ,and I can use manual to change SV anytime before. But with the new
silder added, the manual can't change zhe SV ,but R/S or PID can. And after R/S or PID worked , the manual worked again.....

The SV slider is only sending its signal to the connected PID if the PID mode is active as far as I remember.

forgot it. I set an upper limit of 210C, that make it didn't work....
