Group functions of the monitoring systems
To significantly limit the total number of rules and automatic actions stored in the "Logical Schema," the smart monitoring systems from Didactum offer a "Group Function." Here, you can add a large number of intelligent sensors or potential-free (dry) contacts to a group.
Note from the technical editors: The screenshots shown depict the responsive web GUI of the Didactum Monitoring System 300 with the final firmware from June 2020.
Didactum example: Group function for dry contacts
In our example, we want to group the input contacts located on the dry contact expansion unit. If one of the 64 digital/potential-free dry contacts changes its status from "Normally open" (NO) to "Normally closed" (NC), the responsible IT administrator must be informed immediately by email.
Set up email alert when the dry contact is triggered
Let's now create an email notification together. The email alert for switching the potential-free contacts should include the Didactum macro functions. The Didactum macro functions %5, %6, and %7 automatically output the message of the affected dry contact. Macro function %8 reports the ID of the switched dry contact.
As the trigger for the email alarm, we select the "Alarm (High)" state of the potential-free contacts below. We now click "OK" to apply the settings. The newly created group "Fault Reporting Contacts Building Services" now appears in the web interface under "System Tree." By clicking the floppy disk icon, we permanently save the settings to the non-volatile memory of our smart measurement and monitoring system.
Creating a group of dry contacts / potential-free contacts
You can create a new group in the German-language web interface under "System Tree". Click on the "+" symbol in the upper right corner and select the "Group" element.
