Hi,
I have a question about a Modicon TSX 3721 processor. I am new to this type processor having only dealt with A/B, Rockwell. The processor has an LED for I/O that is red. Am I right in assuming this means an I/O fault? The reason I ask is I have PC/ monitor HMI that gets info from this PLC and some of the functions are not acting correctly. THis whole setup is French and I have no software or program, etc.. Any ideas if this does mean a problem and if so what to look for. I know its limited info, but its really all I got.\thanks
