(12 BIT)
The module lights the green RUN indicator when operating
without fault, or lights the red FAULT indicator when it detects
fault conditions.
If the module is operating correctly, the module will
be receiving BTRs and sending BTWs. The indiĆ
cator light will indicate grenn/flashing green.
If the indicator is blinking green, the module
has not received a configuration block transfer
write.
