System Tags

Description

The following System Tags are included in the Productivity Suite Programming Software. The Table provided below contains all the Tags organized by their Purpose. The following are the

Tags included in the Table:

Run/Stop Tags: These Tags indicate Run or Stop Modes, as well as the Run/Stop switch position.
Various Boolean Tags: The I/O Error Tag indicates that a module in the system has a Module Status Bit set. Examine the Module's Tags or the Logs for more detailed information.
Battery Tags: These Tags allow monitoring the status of the CPU's Battery.
>CPU and Project Tags: These Tags provide information about the CPU and about the Project.
Scan Tags: These Tags provide Scan information of various sorts. Note: The Total Scan Count Tags update once per second. If fresh Scan Count information is needed on each Scan, use a Counter in ladder instead of these Tags.
I/O Configuration Tags: These Tags allow for detecting a Configuration Error and inspecting the installed hardware. Since Configuration Errors are reported one at a time, clearing one Error could result in another Error being reported. When Errors occur, it can also be useful to examine the Logs for additional information.
Array Error Tags: These Tags allow for reporting of Array Index Errors.
Time Tags: These Tags are all related to Time. Most are used for reading and setting the Date and Time of the Real Time Clock. The RTC auto-adjusts for leap year, but not for daylight savings.
Log Tags: These Tags allow for detecting the presence of Errors and retrieving descriptions of the Errors.
