12.2 Replacing a non-redundant PGM
This procedure can be performed only while off-process.
We recommend that you proceed with extreme caution whenever replacing any component in a control system. Be
sure the system is offline or in a safe operating mode.
Component replacements may also require corresponding changes in the control strategy configuration through
Control Builder, as well as downloading appropriate data to the replaced component.
Perform the following steps to replace a non-redundant PGM
Loosen screws at each side of the module cover that secures the PGM to the IOTA board.
Loosen the plastic screw on the front of the PGM cover. Be careful not to strip the plastic screw head.
Carefully remove the PGM from the IOTA board and connector.
Insert the new PGM onto IOTA board making sure that the PGM circuit board mates properly with the IOTA
Secure the PGM to the IOTA board with two screws located at each side of the plastic cover.
Using a #2 Phillips screwdriver, hand tighten the plastic screw on the front of the module cover. Be careful
not to strip the plastic screw head.
The new PGM boots up to ALIVE or NODB state.
Load firmware which is the same version as was running in the old PGM.
From Control Builder, perform a 'Load with Contents' to the PGM.
