Request of Information about Citect license


Thread Starter

Wilfredo G

Dear Sirs:

I am developing an application in which we need to acquire information for the managerial level.

There are several zones of the plant that possess a 5000-point Citect license. There are other zones of the plant where we need to acquire data and it is enough with a 1500- point Citect license.

The question is the following:
Should all the licenses have to be 5000-point in order to acquire data for the managerial level?

Thanks for your helps

Hi Matos,

It is not necessary to have all the licenses for 5000-points Citect license. The license to purchase depends on the maximum number of points you wish to configure at a particular HMI station.

You should post this one to the Citect users list at [email protected] - its a great resource.

It doesn't completely answer your question, but in case you weren't aware, Citect Manager licenses only come as 5,000 points or 150,000 points.

The IO_Server part of Citect does not seem to care how many points a Licence has - it only looks to see that a Licence exists. A Trend_Server, Alarm_Server, Report_Server, or Display_Node does count IO points & checks with the Licence_Point_Count.

The result is that you could have CitectComputer#1 on a network that is an
IO_Server & Display_Node with a 1500 point licence, this display node can only access 1500 points - this is the TOTAL IO from all IODevices anywhere on the network. CitectComputer#2 on the same network can have a 5000 point licence, and read 3000 points from the IODevice attached to CitectComputer#1 and 2000 points from another IODevice.

The trade-off is that your system will be more difficult to maintain, as you would need to run different Project databases for each area of the plant.

I would think your CiTect Distributor would be the proper source for the information you are asking about. In most cases the manufacturer's allow for different tag sizes to accommodate such a scenario. I am quite familiar with Wonderware's Intouch 7.0 and our Distributor (Insource Software Solutions) has many options and solutions to meet these types of Scenario's.
