4.3 Monitoring Data and

Configuration Register Values

Run the ReSource Programming Executive Software. Use the

MONITOR function in DCS 5000/ AutoMax systems or the POINT

MONITOR function in AutoMate systems to check the contents of the

registers. Note that you need to configure the channels before you

can monitor their contents.

Status register values are in hexadecimal format. All other register

values are in decimal.

4.4 Sample DCS 5000/AutoMax

Voltage Input Application Task

The sample DCS 5000/AutoMax voltage input application task in

figure 4.12 is written for a Voltage Input module in slot 2 which is

connected to three singleĆended, 0Ć10V transmitters, which are in

turn wired into a pressure polymerization process.

One transmitter is used to sense the level of the material in the tank.

The second transmitter has its span calibrated for 0 to 3000 psig

(gauge poundsĆperĆsquare inch) and is used during startup

operation. The third transmitter has its span calibrated for 1940 to

1960 psig and is used for process control.
