Please can someone advise me on a way forward.

Thank you in advance for your assistance

Hi,

Can you give a little back story of what the history of the fault is? Did this appear during cycle or after a prolonged power down?

If the machine was working fine and was then powered down over the Christmas break and now you find this error on power up it is likely you have lost data from the CCU which will need reloading. Depending on the type of PCU hardware you have installed on your machine will determine if a data backup is likely to be held locally (PCU20 = internal flash memory only, no internal archive storage, PCU50 = Windows based industrial PC with hard drive, local archive storage possible).

Hope this helps

Luke

 Hi Luke

You are correct I had to reload the backups. I first had to do a NC/PLC clear which allowed me to boot up and then I reloaded my backup. 

The following threads were a big help to help me resolve the issue:
