4.5 Control/Logic Tab
In addition to displaying data, the X-600M can execute logic and control actions. These settings are
made under the Control/Logic menu tab.
With the X-600M control logic it is important to understand the distinction between Events and
Actions. Events occur when certain criteria are met, such as a temperature reaching a certain value,
or a calendar schedule setting an event. Events are either true or false, true when the condition is
met, and false otherwise. The conditions which generate an event can be both simple and complex.
Events, in turn, trigger Actions. Actions are triggered whenever the corresponding event changes
state. An Action can include sending an Email, turning a relay on or off, or initiating a data log. An
Event can trigger more than one Action. For example, an Event can occur when the temperature
exceeds a certain value, the Event then can trigger two Actions. One Action could turn a relay on to
illuminate an alarm light and a second Action could send an Email alert. The scheme of keeping
Events and Actions separate and distinct allows for complex conditions and reporting which is
needed by many real world applications.
The X-600M makes a distinction between conditional events and calendar-based events. Actions can
be triggered by both event types. Calendar-based events are periodic in nature and occur based on
the current time. Conditional events are dependent on the status of I/O, or a more complicated Lua
script.
4.5.1 Control/Logic > Conditional Events
Conditional Events occur when certain criteria are met (e.g. a temperature exceeding a certain value).
The conditions which generate a conditional event can be either simple or complex.
The Conditional Events menu tab presents a list of the current conditional events. To add a new
conditional event, click Add New Event.
