iq-heartbeat bug: Action OK is not called at program start

WebIQ v2.19.0 (and earlier)

  • The connection is established when the WebIQ project starts

  • The heartbeat variable is incremented by the PLC,

  • In the video you can see the variable changing

  • Action (OK) virtual:bPlcConnected = 1 (TRUE)

  • Action (Failure) virtual:bPlcConnected = 0 (FALSE)

    • The graphic "connected" is displayed correctly,

    • but virtual:bPlcConnected is FALSE
