4.3 Monitoring Data and
Configuration Register Values
Run the ReSource Programming Executive Software. Use the
MONITORfunction in DCS 5000/ AutoMax systems or the POINT
MONITORfunction 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.
