Abstract:
A process control device may include a controller having a remote device trip initiation input, a local device trip initiation input, a remote trip condition input, and a local device reset input. The process control device may also include a device trip source determination module configured to determine a device trip source based on at least one of: the remote device trip initiation input and the local device trip initiation input. The process control device may further include a device reset determination module configured to: automatically generate a device reset when the device trip source determination module determines that the device trip source is a remote device trip and based on the remote trip condition input; or generate the device reset when the device trip source determination module determines that the device trip source is a local device trip and based on the local device reset input.
