Thanks for quick reply. But I also wants to reset the toggle fb when I activete the alarm. Can its be done?
It is working to switch off when alarm i active. But the lights goes on again when alarm i off.
Hello @msoenen,
the Mervis mobile app is available for download in the official stores for Android and iOS. However, to use this app, you need Mervis IDE capable of deploying projects to Mervis SCADA. Currently we are working on release of such Mervis IDE, which, with any luck, will be released to public next month.
It was stable during > 2 months but now, I can reproduce the issue systematically with USB port 1 (after a few hours of operation), but not when connecting the same hardware to USB port 2.
Hi @mmcreativ,
the issue might arise, if you try accessing the IP 192.168.8.91 from another subnet. The WiFi interface doesn't have default gateway set, therefor it doesn't know how to reach different subnet. Could this be the issue?
Hello @matt90,
the speed of 1ms is very optimistic and in the real life, you will not be able to get it under 10ms with Mervis. The biggest impact on the overall performance has the Autogen functionality and as I can see from the example, you have it configured on all datapoints. Please, take a look at our tutorial about proper settings: https://kb.unipi.technology/en:sw:01-mervis:autogen-hidden
Also, be aware, that the speed is not deterministic, since the program of the PLC is running in the operating system, sharing resources with other processes.

Hi, thank you very much for your great tutorial. The board lives, and works well. I start to understand how to work with addresses. Previously I made the mistake of creating one group and trying to express all the relays with data points. Now I know it was nonsense. Thanks again very much. :-)
Hello @bart-delaere,
the easiest way is to use a simple DIV function block, via which you will divide the setpoint variable value by 10 before sending to AO:
Hello @nicola-mondinelli,
I just replied to you via email, I'll repost it here:
Mervis currently doesn't have such functionality. We are about to release an active 1-Wire gateway called xG18, via which you will be able to read 1-Wire sensors without the need of knowing their addresses. This will be released to public by the end of the March / beginning of the April.
The OWFS subsystem is able to detect the sensors, but you still need to know which address belongs to which sensor.
Hi @sindyk,
no, your PLC will work as expected. These messages are not valid and they are meant to be valid in next version of MervisIDE, where the licensing of the PLC will be mandatory. You can ignore those for now.
Sorry @jaros for the mystification. The blocks for PLC runtime are indeed called ''getevaltime" and "getevaltime4", depending on which data type you need.
Hello @msoenen,
so far we don't have a support for this platform. It would require to write a bridge between our API (Evok probably) and the API of the my-devices.
