Question: How many unique privilegs levels are there in Citect? 

A lot of other software packages have a very simple method of providing security with a single linear privilege control. With this method you may have say privileges 1 to 16 on your system. You place the required users in each privilege level and they only have access to commands in that level. This give you 16 unique security levels. Users who have used these software packages then assume that Citect operates in the same way and then ask why Citect only has 8 privilege levels.

With Citect security scheme you would normally only need 3 privileges levels, however we decided to provide 8 for any user with unusual requirements. You only need 3 privilege levels because the privileges are used in associated with the areas and you may have up to 256 areas in your Citect project. This gives you a matrix of security which is must more useable than a single linear system. You should also note that a user may belong to more than one privilege and more than 1 area. This gives a huge number of security levels combinations. The total number of security levels is 2 to the power of 256, times 2 to power of 8 which is a number in the order of billions of billions.
