Communication between Beckhoff CX1020 and MonitorPro IEC104

[steve_88vd]

Hi everyone,
I've got the following task - build a project for controlling digital outputs, and reading from digital inputs using a Beckhoff CX1020.
For HMI I've got to use MonitorPro 7.2, as an intermediate stage the communication goes trough TriangleMicroworks OPC server, the project communication is made using IEC60870-5 104CE.
The problem is I can't seem to get it to work and I don't know where I'm missing something.
It will be great if someone's got a working project I could look at.
Thanks a lot
