Hello,
I'm trying to conect this devices with Modbus RTU using Somachine basic but I don't get any response. The speed, parity, bits and timeout are the same in both devices.
M221 configuration:
- speed: 19200 bps
- parity: even
- timeout (x100ms): 10
- adressing: master
ATV312 configuration:
- speed: 19200 bps
- format: 8E1 (8 data bits, parity even)
- adress: 1
What I am trying to do is to read one variable inside the ATV312, in this case 9004 is the Modbus direcction linked to the Type of ramp.
And this is the program,

I need some help with this, I don't know where I'm mistaking.
