I've to connect 2 hmi Bartec BDT5 (i've found that ET65 from Exicom - Stahl it's the same product) with a PLC TSX3722 using Modbus RTU. I use the TSXSCP114 (RS422/485), the cable TSXSCPCX4030 e the electronic barrier BSG5 (for Eex application). I've tried to configure the BDT5 as modbus master & as modbus slave but i'm unable to communicate with the PLC. Has anybody tried to link these components?

Thanks for your support,
Max

 

I have similar problem . I can't configure Exicom ET-65 to communicate as modbus master with Mitsubishi PLC QnAS.
