Hello,
I have an application running at one of my customers, which there is a V1040 PLC communicating via Canbus with 7 EX-RC1 nodes of which two modules have been installed recently.
Each EX-RC1 has a couple of expansion modules connected to it and exchange digital and/or analog data with the PLC.
I have followed all the instructions on how to install and configure all the devices, and my application was working fine with 5 EX-RC1 nodes. The problem is, when I installed the others two nodes, my application started behaving strangely: The data (only MI's) coming from two specific nodes (the nodes with analog expansion modules) started oscillating between right and ramdom values. However, the communication among nodes was apparently ok, as I could notice it by watching the values of MI Status Message (between 0 and 1);
The problem only stops if I disable the Unican send blocks that are sending analog input values. Moreover, this oscillattion only happens on my PLC. If I get online on the EX-RC1, I do not observe any oscillattion;
Do you guys have any idea of what is going on?
