Calibrate/communication indicator. This indicator will
flash green when doing block transfers. It will flash red
duringcalibration.
Run/Fault indicator. This indicator will flash green
until the first valid block transfer write has been
received. If a fault is found initially or occurs later, the
RUN/FLT indicator turns red.
At power-up, an initial module self-check occurs. The RUN/FLT
indicator will be green when the check is completed satisfactorily. It
will flash green until the first valid block transfer write has been
received. If a fault is found initially or occurs later, the RUN/FLT
indicator turns red.
The bottom indicator is the calibrate/communication indicator. This
indicator will flash green when doing block transfers. It will flash red
during calibration.
Possible module fault causes and corrective action are discussed in
Chapter 7, “Troubleshooting.”
In this chapter you learned how to install your module in an existing
programmable controller system and how to wire to the remote
termination panel.
