      How to run a function when a page is shown in PowerLogic SCADA v7.20; Using "On page shown" and "While page shown" properly

      To run a function when you click on a page in PowerLogic SCADA v7.20 (PLS), add the function to the Page Properties of the current page in Citect Graphics Builder. Select the Events tab, check the On page shown box and enter the desired function in the On page shown command box.

      If you add the function to the While Page Shown, the function will not run if it contains a blocking function.

      For example, consider the following function where cnt1 has been defined as a Local Variable.

      IF cnt1<1000THEN
      // cnt1=TagRead("MyPM870\MMXU1\Hz");

      Calling this function from the "While page shown command" box will work because there is no blocking function inside Test().

      Alternatively, consider the following modified Cicode with TagRead added, which is blocking function:

      // IF cnt1<1000 THEN
      // cnt1=cnt1+1;
      // END

      This will NOT work and until the tag will be available from the cache, it will generate a hardware alarm (System Alarms page)--"Foreground Cicode cannot block"--and the execution of the function will be cancelled. The alarm will disappear after the code execution has stopped.

      In the following screen capture of the Client Kernel, we can see that PageFG (page foreground cicode) is in the Stop state since Test() contained a blocking function.

      What to do if PowerChute Network shutdown configuration wizard displays blank Network Configuration page?

      After installing PowerChute Network Shutdown when the configuration wizard runs the PowerChute Setup: Network Configuration page display is blank.

      PowerChute Network Shutdown version 3.1

      All supported Windows OS

      Corruption in pcnsconfig.ini


      We recommend uninstalling PCNS 3.1 and installing PCNS 4.2

      If continuing with PCNS 3.1

      1 - stop PowerChute service
            Open command prompt as administrator and type net stop PCNS1

      2 - Open pcnsconfig.ini using wordpad or notepad
            The default path to pcnsconfig.ini is C:\Program Files\APC\PowerChute\group1

      3 - Enter the system ip information to [Networking] localHostAddress = for IP v4 or UnicastAddress = for IP v6

      protocol = https
      httpPort = 3052
      httpsPort = 6547
      NetworkConfig = IPV4
      ESXiVirtualInstall = false
      HyperVVirtualInstall =
      MulticastAddress =
      IPv6NetworkConfig = unicast
      localHostAddress = 192.168.1.X
      UnicastAddress =

      4 - Add user name, password, and NMC IP information to [NetworkManagementCard]

      mode = single
      IP_1 = 192.168.0.X
      port = 80
      protocol = http
      enrolWithNMC = true
      acceptCerts = false
      username = apc
      password = apc

      NOTE: user name and password are not visible. You need to enter username = along with password =. This information will be read and deleted from the ini file when the service is started. See Knowledge Base document FA159758 for assistance with PCNS user name and password. If port has been changed from 80 and protocol has been changed they will need to be adjusted accordingly.

      5 - Restart PowerChute service
           from command prompt type net start PCNS1

      6 - After restarting PCNS1 service log into PCNS web page and select Shutdown Settings to complete the configuration.
