Analog Input Examples

The process input is a 4 to 20 ma signal that represents a flow measurement range of 0 to
200 gallons per second. Therefore, the VCI block output range is configured to 0 and 200. The
totalizer input is the VCI block result.

DIRECTION = UP
RATE = SECOND
SCALE FACTOR = 1.0
Current time = 8:00 AM
Current Total Count = 0

IF:

Input = 100% (20 mA) constant for one hour

THEN: At 9:00 AM, total count = 720000

IF:

Input = 50% (12 mA) constant for one hour

THEN: At 9:00 AM, total count = 360000

IF:

SCALE FACTOR = 100.0 and Input = 100% (20 mA) constant for one hour

THEN: At 9:00 AM, total count = 7200
