1715-IF16 This section describes the tags that are associated with the 1715-IF16 module.
ModBFieldPowerVoltage2 DINT
Reports the voltage from the field power supply for the specified module and field power input.
Accuracy is ± 500mV
Ch AB_1715_ChStatusStruc:I:0[8]
Current / Voltage
Status Array
Each element of the array
comprises
Current: REAL
Reports the current for the channel in
milliamps and with an accuracy of ± 2
mA and ± 10% of measurement
Voltage: REAL
Reports the channel voltage at the
output terminals in units of millivolts
and with an accuracy of ± 500 mV (The
voltage element cannot report values
below 0 mV
