Answer / raj anu raj

Every manufacturer issues catalogs, O&M manuals with their
products or download them from their respective site. Just
go through them. They will clearly explain you the error
codes which are visible(flashing leds) in the PLC. From
them trouble shooting will be easy.

plc trouble shootings? ..

Answer / ponnuswamy balakrishnan

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.

Answer / rajesh kumar rajesh

The programmable logic controller (PLC) is changing to
reflect the demands of sequencing and continuous processing
applications. The PLC can be thought of as a hardened
computer with high speed I/O and communications ports with
bus interfacing for multiprocessor or coprocessor
enhancements, and a BIOS that supports those features. PLC
manufacturers now retain control over both aspects of the
PLC which interoperate in a proprietary manner. Via the
delineation of the two may come a standard real time
operating system or real time kernel which would give rise
to true applications portability.
