GE Mark VIe System Manual page 183

Perform the following troubleshooting steps if needed:
• It is not possible to connect to the designated controller if the controllers are set in the dc determination state. Going
online with each individual controllers is required.
• The ToolboxST application may not display any information in the Status tab for the faulty Mark VIe control if it is set
in the Power on/d0-MASTER_INITIALIZATION state. The other two controllers are suspended at d1-State Designated
Controller Determination state.
• If the controller halts before d0-MASTER_INITIALIZATION (at power on state), the problem could be with the
controller. If the controller halts at d0-MASTER_INITIALIZATION state, the controller may have lost its IP address.
• If the controllers halt at the d1-dc_DETERMINATION state, one of the controllers may be unable to communicate to
either IONet 1, 2, or 3 port.
• If all the controllers halt at the d3-INPUTS_ENABLED state, at least one of the I/O modules configured as a required
module may not be communicating with the controllers.
