Do you have a hardware error interrupt OB so when hardware is offline, the plc does not stop?

What time out for your communications are you using?

I cannot use dropbox.  Can you put the project here?  If it is too large, just remove big blocks that have nothing to do with the problem.  Just make sure it compiles after you rip out all the blocks to upload here.

We have a PLC-1214 DC/DC/DC v4.1 installed in a train that is moving, this plc is connected by ethernet to a router.

Ten we have another PC-1214 in the factory conectec to a point to point via ethernet. This one is conected to the router via wifi.

Then we have the computer that will be a pc-system and will conect via the other two via wifi through the router.

The comunication is working and the train is receiving the signal.

The problem is that the block send in the factory has a problem (I don't know wich one) and the plc goes to error (red led), the message of error says that there are some individual errors grouped in that message (so imposible to know wich one is it).

When I delete the block send then it says that everything is ok.https://www.dropbox.com/sh/xyqyiodrw1t5tg8/AADWVRAwAugQ9I67uTAtPWREa?dl=0
