Limit Citect SCADA to one user

Brian

Hi All,

Citect 2016 R2 Update 21.


We have a Client only PC that auto logs in with Operator Privileges and Citect Client will auto start.
Recently someone logged in as Administrator which took the License and the Operator instance could not run.

Is is possible to disallow an instance of Citect to run under a user, is another instance is already running under another logged in user?

Citect cannot be run in Service mode as the customer is making use of SCADAPhone which requires a Citect Runtime opened on Startup.

Cheers

  • It is possible. Check if a Windows user group of Citect.RuntimeUsers or SCADA.RuntimeUsers was created on that machine. If a Windows logon user is not in this group, Citect runtime cannot be launched even for the local administrator. I am sure Plant SCADA 2020R2 (v8.3) and 2023 (v8.4) can restrict users from launching Citect runtime. I am not sure your version. If either of these group doesn't exist, you could create your own group and use this group to apply ACL to citect.ini file (remove all other access users). If citect.ini file is not accessible to a logon user, the citect runtime cannot be launched. Hope this would help.

    The prompt message for the user who is not in RuntimeUsers group.

    Thanks Jacky, that's a great option.
    Currently they are Running 2016 so we will have to follow the second method until they upgrade later this year.
