It doesn't matter which brand of PLC you are hanldling
with. You should know the basics of electrical circuits and
able to read circuit drawings perfectly. PLC perform the
programme what we write for a specific objective.If it
ackowledges the inputs signals ( Sensors,switches etc)it
will automatically give o.k for output( motors and
temp.controllers etc.).So first check the input & output
signals in the plc for the broke down circuit. If it is
o.k.then proble should be in the hard wire line. May be the
wire groundeded or the defective component.
