Issue
How to recover I2 controller with auto started corrupt/bad PE program and flash backed up with this corrupt/bad program.
Environment
I2 Controller
Cause
If the program is in flash, and the ACCRestartMode is set to ACCWarmToCool and the ACCStatusFlash is set to AccValidFlash, you’ll find yourself in an endless loop when trying to power down and restart. What needs to be performed at this point is to get the corrupted/bad auto start program out of the backed up flash. The corrupted program can be one that has just been created/edited or imported and then saved to flash.
Resolution
Get the corrupt/bad program out of the controller and its flash:
- With the WS in offline edit, dump the corrupted program/s to file and then delete it/them from the controller. Now send the I2 controller to text file. Edit the controller and write down the parameters i.e.….Name, model #, commport, serial # and infinet ID. Then delete the controller.
- Bring WS online, manually create a new I2 with a temporary name, same serial #, same model #, same comport and an infinet ID that is not used… ie (if you have for example less than 100 infinet controllers use infinet id of 101) select apply. The temporary I2 just created should come online. Once online, delete it. (The reason for creating with a new temp name and Infinet ID, is that a newly created controller will create an empty controller and empty out the flash.)
- Now create a new I2 with the original name, commport, serial # and original infinet ID. Once online import the controller dump file we saved, reload and back up to flash if needed.
