  • CitectSCADA 5.xx
Summary:
Interact is an HMI-package from CTC (Computer Technology Corporation). In Europe Getronics Belgium, Geveke Electronics Netherlands, IQ automation Germany, and IP Systemes France know this package well. It is designed for fast integration , for example for machine builders,... The development is done in Win , the runtime application is DOS.

How can Citect be setup to communicate via DDE to Interact?

 

Solution:
Requirements:
  • Interact 5.1 run on DOS-PC : Powerpack ( PTM/AMM/GMM )with NetBIOS ( NET )
  • Interact DDE - license on WIN-PC : DDE SERVER, KA-82303-500
  • Citect 5.0 on the same WIN-PC

Step 1: try CTC-Interact demo-files

  1. Run on Interact Dos PC the demo from CTC ( with demo DRV + NetBIOS )

    Interact NetBIOS setup : PWSTATION
    DDEPC any privilege

  1. Connection to second WIN PC with NetBIOS
  2. Install DDE-server on Win PC

    node-name = DDEPC
    updates/sec= 50
    RUN DDE SERVER

  1. Excel on WIN PC

    RUN EXCELL APPLICATION CTC

  1. DDE

    SERVICE NAME = INTERACT
    TOPIC NAME = VALUE numeric
    TEXT string
    ITEM NAME = the driver for interact

e g =Interact|VALUE!'PWSTATION\MITA\0$D6141

Step 2 : Citect

If the Excel-DDE-Interact works , Citect will work in 3 minutes

  1. Run on Interact Dos PC a small project with MITA-driver

    Interact netbios setup : TESTDOS
    DDEPC any privilege

  1. New project
  2. DDE-driver Express I/O setup
    I/O Device Address = Interact|VALUE ( service name | topic name )
  1. Tags variables
    Tags Address = testdos\MITA\0$D6141
    Value from - 32768 till +32767
  1. Page
    testpage graphics builder with 1 tag ( see 3 )

This works fine and also very fast ( driver Citect )
