  Dobrý den @ogast, ani jedna z těchto komponent v HMI momentálně není. V příští verzi MervisIDE plánujeme tlačítko s odkazem. S pozdravem, Martin Kudláček

  Hello @Jan-Toth, that is currently not possible. But you can have a digital indicator with many values, each value can have its own color. But you cannot change the text. This is helpful if you draw pipes of your heating system and you want to change the color of the pipes based on the temperature. Each pipe will be a digital indicator. Different values of the temperature would display different elements of the digital indicator - which would display different images (blue pipe, red pipe etc) Martin

  Mervis a komunikace pres webova API

  Dobrý den @JVA, dovolil jsem si přesunout Váš dotaz do samostatného vlákna, protože se týká obecně komunikace přes webová API. Mervis takovou komunikaci nativně neumí. Obecně doporučujeme: Pokud umíte programovat v Pythonu, tak si můžete napsat službu, která bude parsovat dané API a ukládat data do ModbusTCP server kanálu v Mervisu Vyzkoušet například Node-RED, ve kterém je práce s API mnohem jednodušší. Více o Node-REDu na našich jednotkách se můžete dočíst zde: https://kb.unipi.technology/cs:sw:03-3rd-party:nodered?tns S pozdravem, Martin Kudláček

  Dimming funtion AO

  Hello @Martin-Kudláček , I have been able to solve the 1-10v dimming problem. It was a bit of a puzzle, but in the end it went well. I have created an extra node to a div. I solved the EQ problem by adding a LT compare function so that when the counter reaches 0 it automatically becomes 1 again. When I now click the dimmer button on the hmi, the LED lamp gradually rises and stops when I release it. I press it back in, it goes down again, etc. The LED lamp driver uses about 2 milliamps so i can connect enough drivers for the room lighting. I am very happy with this solution and would like to thank you for your support. Many regards John-paul

  Thank you for a replay. It is remote environment, and I am afraid to lost everything once I detached a PLC. Can I reattach PLC under porxy or remote connection ? Hopefully I would like to know UDP port number mervis using when finding connected PLC under the same LAN. thank you.

  @Matt Did you manage to write a better PID implementation in Mervis that you could share? When using the built-in PID logic for controlling hydronic underfloor heating valves (huge time delay), it only acts as a pure PI controller.

  Hello @Petr-Helebrant, you can use Digital Indicator for that. In the settings, you can assign different images to different states of an integer variable. Best regards, Martin

  Yeah , but i don't see in my case how put delay timer because my cycle finish if time and not action. to example "The object finish to move" i put delay with "TON" so boolean i understand how to make but not with time. I try this with DO WHILE but the program don’t block in the DO WHILE and the refresh of temps_1 and temps_2 is the same so diff_temp =0 I want maybe 30/50 ms of delay to have a good derivate of my temperature. Do you have idea how use delay timer to have 1 times of the PLC not refresh and one other refresh and when the sub is good the action is make ? i try getevaltime4,detdeltime4,plc time,..etc i'm block.

  Dobrý den @linex, na co nejspíš narážíte je pomalost vyčítaných hodnot. Ta souvisí s funkcí autogen. Zkuste si prosím projít tento tutorial: https://kb.unipi.technology/cs:sw:01-mervis:autogen-hidden S pozdravem, Martin Kudláček
