I have a slc5/05 writing to a plc5/40 processor ( using message), everythings works ok for hours sometimes days then it gives error 37 and stops sending information, the error bit sets I have cleared the error bit in the set up screen but it does not fix problem so far the only way I have been able to clear fault is to reload a program with no faults in it , I am assuming there is an easier way I just have not found it, any suggestions would be appreciated
