Unity Pro - M580 and Tesys-T over 2-wire Modbus

[lonegator 0]

Does anyone out there have any experience with setting up communications between a Unity processor (I'm using an M580) and numerous Tesys-T LTM R Modbus controllers over 2-wire Modbus?  I am stuck and have been unable to get a resolution from Schneider support.  I'm not sure if there's an issue with the setup of the Tesys-T modules, the EGX100 gateways being uses, or with my program setup in Unity.  I've stripped down my program to one gateway and one Tesys-T, but still cannot establish communications.  I don't get any errors.  I just don't get any response at all.  Any experts out there who might be able to help me out?

What are you using to communicate with the tesys? Io scanning or read_var write_var function blocks?

lonegator, how did you resolve this? I´m currently doing the same: I have to read/write drives on Modbus RTU throught the EGX100
