PAC8000 PROFINET Scanner Power-up and Restart
Once PNS is powered up, the OK LED remains ON. If a fatal error occurs during powerup,
the LED blinks instead.
If the module encounters a hardware failure, invalid firmware image, or the powerup
diagnostics fail, the module will not become operational; it may enter firmware update mode.
Cycling power to the module should restore operation.
