Rules

General

There are different rules for tags and devices. Rules can only exist in a workspace and relate to a tag or device.

Creation

Inside a workspace you can create a new rule. After creation you can select the type of rule after which more relevant configuration is shown.

Rule types

Device connection time checker

This rule will create an event if a device doesn't connect within a given interval. For example a device should connect every X interval. If the device doesn't connect every 60 minutes an alarm event will be created.

Thresholds

This rules can be used when some alarm must be raised when some value is crossed by a datapoint of a ag. For example maximum temperature alarm events or tank low level alarm events. There are two different types of thresholds; High level and low level. Both types are the same but work inversely. For example a tag with a threshold/setpoint value of 50 and a type of High level, will cause an alarm event when current value is 40 but then goes to 51.This alarm event will get solved when the value goes back to lets say 47 depending on set hysteresis of the rule.

Severity For each setpoint a severity must be selected. The severity means the impact of the alarm. This severity level is used and shown in alarm events and can be used to notify only specific users of different severity channels.

For example think of a user that only wants to know about critical alarms while another might want to receive all alarm events.

If the type is high alarm the setpoint values must go from low to high in severity, for the low alarm the inverse is the case.
