All PLC or DCS will have a feature to print process alarms/events as they arise. In the 80s/90s this is how engineers used to analyze sequence of events. They have to read manually printed pages and pages of Alarms/Events, typically printed from dot matrix printers
. Today, Alarm/Events are recorded in databases. However, the facility to print alarms still exist in all Control Systems. Typically this feature can be configured from the Operator's console machine or HMI
This is how Open-Plant Connector's TCP Channel collects alarms/events from any process control system
This TCP/IP print allows printing directly into an application (such as the Open-Plant Connector) listening to a port. This is how Open-Plant Connector's TCP Channel collects alarms/events from any process control system.
