Abstract:

Continuous equipment operation is facilitated despite disablement of an automation controller for controlling the equipment. A safe state in which equipment is to be maintained upon disablement of the automation controller is determined. Safe state data is provided for configuring an I/O module, through which the automation controller controls the equipment, with the safe state data to facilitate maintaining the equipment in the safe state during disablement of the automation controller. In one embodiment, upon subsequent enablement of the automation controller, a current state of the I/O module is evaluated and an automatic control state into which the equipment is to be transitioned is determined. The equipment is then transitioned to the determined automatic control state.
