Automatic Control Module
Overview
Automatic Control Module automatically sends commands depending on certain conditions. Unless you register the module, it works in the demo mode. The duration of a full functional demo is limited to 10 minutes after restart. The module operates under control of the Server application. The form shown below is designed to configure the module.
Conditions required for sending commands specified as triggers of several types:
- Channel data trigger. The trigger fires if value or status of the input channel satisfies the condition.
- Channel data change trigger. The trigger fires every time when value or status of an input channel changes.
- Event trigger. The trigger fires if an event satisfies the condition occurs.
- Time trigger. The trigger fires on the specified dates and times.
- Command trigger. The trigger fires if the Server application receives the specified command.
Each trigger contains a set of commands which are sent if the trigger fires. The information about firing of the triggers is accessible on the Log page or directly from the ModAutoControl.log file. This file is located in the Server logs directory C:\SCADA\ScadaServer\Log
