This item indicates when an I/O channel is open.
Item 85 - Channel Isolated
This item indicates when an I/O channel is isolated.
Item 86 - Normalized Process Variable
Normalized process variable holds the analog value read from the device as a floating point value. For devices
with adjustable ranges, values are calculated by using the zero and full scale range values.
Item 87 - Raw Process Variable:
Raw process variable holds the analog value read from the device as an integer value. For devices with adjustable
ranges, values are calculated by using the zero and full scale range values. When the raw integer format is used
values are in the range of 0 to 4095. Values for an ideal 4 to 20 mA sensor are:
DCU Process Variable
Input Output
0 mA 0
4 mA 682
12 mA 2048
20 mA 3413
24 mA 4095
Item 88 - AC Voltage
The AC voltage can be read with this variable.
Item 89 - Temperature
The temperature in degrees C can be read with this variable.
Item 90 - Battery Current
This variable represents the battery charge or discharge current level. Positive values indicate battery charging
while negative values represent battery discharge.
