Hi, I have a problem with a cpu slc 5/05 (1747-L552), 32k Mem 0S501 series C, I am using the MSG instruction to ethernet communication, it works for a few days very well, but later the communication turns to slow, and sometimes stop for complete. The way that the communication is restablished its making a cycle power to the processor. Below appear a part of the logic that I am using to send and receive information to DVT system by ethernet. Somebody knows if there is another way to configure this instruction and never gets faulted?
