ATR313 + PL300 + PL250

Hello
We have 4 kilns TVA70 (ATR313 + PL300 + PL250).
    Software version: Alfa 2.29.
    Connection:
    - ATR313 (COM1, DB9F) with PL300 (contacts 25, 26, 27) RS485, 9600bit / sec;
    - ATR313 (COM2, DB25F) with PL250 (contacts 43, 44, 45) RS485, 19200bit / sec;

Questions:
1. Is it possible to join four ATR313 into one RS-485 network for data transmission third-party SCADA for Protocol Modbus RTU?
2. To which connector will it be connected?

Best regards

Hi,
in your application it is not possible, because you are using the COM2 to management the PL250. If you don't use the PL250 you can setting the COM2 port configuration as SLAVE and you can use a SCADA to read the ATR313 Modbus Registers, throut RS485.
See the modbus registers Use guide attached.

Best Regards.

Hi
Thanks for the quick response.
Guide read:
"The module PL300 with Terminal ATR313 via serial comunication RS485 and Pixsys protocol."
Can I be Pixsys protocol switched to Modbus?

Best Regards.

Hi,
Pixsys protocol can not switched to Modbus. The ATR313 needs COM1 RS485 to management the PL300.

Best Regards.
