Abstract
A control system contains a communications network, a host computer and a programmable logic controller (PLC). The host computer includes prioritized alarm queues for receiving prioritized alarms from the programmable logic controller. Alarms fall into either a local or a global category, and each category supports three types of alarms: warnings, alerts or faults.
Claims13
A control system for processing alarms in a data communication network, the control system permitting prioritization of said alarms, the control system comprising:
- (a) a host computer connected to said data communications network;
- (b) a memory in said host computer, said memory including a plurality of local and global alarm queues;
- (c) means in said host computer for writing an alarm to a selected one of said alarm queues;
- and
- (d) a plurality of other computer-based devices connected to said network, said computer-based devices including means for generating prioritized alarms on said network, wherein said plurality of alarm queues include a fault queue for storing fault alarms, an alert alarm queue for storing alert alarms and a warning queue for storing warning alarms.
A control system having a communication network permitting prioritization of alarms, the control system comprising:
- (a) a host computer connected to said network having a system task, a plurality of global alarm queues associated with said system task, a plurality of user tasks, a plurality of local alarm queues associated with said user tasks, said plurality of local and global alarm queues for receiving alarms from said network;
- and
- (b) means connected to said network for writing said alarms to selected one of said alarm queues.
