Controller Not In Controlling State - GE Mark VIe System Manual

8.3 Controller Not in Controlling State

Pre-requisites for attaining a controlling state include:
• The controller should have the base load, firmware, and application code downloaded.
• All controllers (in dual or TMR) should communicate with each other over the IONet.
• All I/O modules (if configured as required) should be able to communicate with the controllers.
Note The Mark VIe control system may not reach a controlling state due to faults in either the I/O module, the IONet switch
or the controller itself. A single faulty controller can prevent the other two controllers from reaching a controlling state.
Perform the following procedures if the controller is not attaining a controlling state.
