Prerequisites
• These procedures can only be performed 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.
• Note that all modules are keyed.
1 Loosen screws at each side of the module cover that secures the controller module to the IOTA board.
2 Carefully remove the Controller module from the IOTA board and connector.
3 Insert the new controller module onto the IOTA board making sure that the controller circuit board mates
properly with the IOTA board connector.
4 Secure the controller module to the IOTA board with two screws located at each side of the plastic cover.
5 The new controller will boot-up to ALIVE or NODB state.
6 Load firmware. Ensure that the version is the same as was running on the old controller.
