Allen Bradley PLC2 Revived
Dungeness A is a legacy Magnox power station, that was connected to the National Grid in 1965 and has reached the end of its life. While it is now being de-commissioned some of its existing systems are required to run for a little longer. This includes a rather old Allen Bradley PLC2. The backup tape for this PLC is literally that, an audio tape. After a recent power spike, the PLC lost is program and the backup tape was so old, it disintegrated when it was used.
With our in house expertise and store of legacy software we were able to re-write the program from an old printed copy. Now the PLC is back in service and will see the station through to complete closure.
