Reading judgment values (P.V. values) from sensor amplifiers

Judgment values (P.V. values) are read from the IN area to which the ID number of

each sensor amplifier is assigned.

Device assignments:

"Monitor Data (84 Words (168 Bytes)) Assembly Instance

(Instance ID): 64H" (Page 3-9)

This example shows how to read the judgment values from the sensor amplifiers

ID01, ID02, and ID03.

(1)When the judgment value of a sensor amplifier is updated, the new judgment

value is entered into the IN area via cyclic communication.

If the judgment value is correct, the parameter range is -99.997 to +99.998.

If the current value is over range, under range, or invalid, the previous value is

retained without updating the current value. Use the value with the judgment

value property.

(2)The properties of the judgment value (Current Value n Over Range (each bit of IN

area [6]), Current Value n Under Range (each bit of IN area [8]), and Current

Value n Invalid (each bit of IN area [10]) are entered. If the judgment value of a

sensor amplifier is "over", "under," or "invalid," the bit corresponding to the ID

number of that sensor amplifier is set to 1.

*For the SK-1000 Series, the judgment value is stored in the current value 0.
