The table below defines CitectSCADA projects specifications:
|
Configuration Projects |
1022* |
|
Number of Variable Tags defined in CitectSCADA |
4,194,303 (but no more than 500,000* is the recommended) This is a system wide limitation for a running system. Tags in every project included in the project you are currently compiling and running will contribute to this figure, regardless of clustering. Be aware that if you are using one or more tag based drivers in your project, the figure depends on the bit length of your variables defined for the driver(s). This is due to the need for these drivers to use OIDs to identify each tag. For example, a tag based driver that uses 32-bit digitals may reduce the number of possible variables by 32 (i.e. if your project contains only 32-bit digitals, you can have a maximum of 131,072). If no bit size is defined for digitals by for the driver, it defaults to 16. |

*There is no actual limit to these values; they are maximum recommended values only. However, exceeding this number can impact the Trends Server performance (CPU loading) and the CPU loading of the Client displaying the Process Analyst.
