IC697BEM713
Status Indications
Three green LEDs at top of module provide module
status information as described below.
The top LED (MODULE OK) LED is ON when the
CPU software completes its power-up configuration
of the BTM, and has polled (or attempted to poll) each
expansion rack in the system. It is OFF when any of
these conditions are not met.
The middle LED (Programmer Port Enabled) is the
Programmer Port Active LED. This LED is either blinking or ON when the programmer and the PLC are
communicating. It is OFF when they are not communicating. Note that this port is not used in communications between the Windows programmer and the
PLC.
The bottom LED (Expansion Port Enabled) provides
the status of the expansion bus. This LED is either
blinking or ON when the BTM is communicating with
the Bus Receiver Modules connected to it through the
parallel I/O bus link. It is OFF when they are not communicating.
