      Hello @todward,
      tha IDE 2.0 is quite ancient and it dates to the times when the HMI editor and IDE has been separated and the API has been different. In current Mervis IDE 2.3.0, the API is working:

      0_1588855031312_2f0b6a41-a698-4be5-9cff-ea7b715b197c-image.png

      On a side note, you can make variables available over ModbusTCP or BACnet/IP server in the Mervis 2.3.0. Maybe it will be more convenient for your other system.

      Best regards,
      Martin

      Hello. The release contains updates that are not part of standard apt-get update process so it is recommended to re-flash the SD card and upload your project again.

      If you want to update the standard debian packages, then apt-get method is always possible after mounting the FS for writing.

      Hi,

      I think that you could connect the switchoff delay block behind the B31 as you suggest or a simple gt/lt (greater than/less then - but this will not solve the hysteresis as the B31does).

      As it is written in the documentation, X is the actual temperature from a sensor, W is the setpoint when the output will become True, Xp is the hysteresis - eg if set to 5, the out will become True once the teperature goes below 90-5=95 thus the relay will not switch that frequently. Take a look at the graph on the help file….
