Data display screens allow you to monitor the value of registers in the SLC
or PLC. The DTAM continuously reads the registers to update (at a user-
defined rate) the displayed values.
This is how a data display screen may appear:
Tank Level = 33 Gallons
10% Full Press NEXT
To construct data display screens, you need to specify:
•
The type of screen as data display
•
The type of data stored in the PLC or SLC register
•
The register to access (address)
•
Any data format and display information
•
The display position for the data
•
Any additional text information that you want to display
Data in controller data files can be scaled to standard engineering units such
as gallons, pounds, feet, etc. Data is scaled by setting up a proportion
between the controller register data limits and the DTAM data display limits.
Refer to the description of scaling in Chapter 3.
Note: The 32 bit BCD data format cannot be scaled.
