Appendix A Isolated Analog I/O Module Tag Definitions
Ch[x].AlarmDisable BOOL Disables all alarms on the module. • 0 = Enabled
• 1 = Disabled (default)
Ch[x].ProcessAlarmLatch BOOL Latches all Process alarms if they are configured not clear
until explicitly unlatched.
• 0 = Latching disabled (default)
• 1 = Latching enabled
Ch[x].RateAlarmLatch BOOL Latches all Rate alarms when they are configured not to
clear until explicitly unlatched.
• 0 = Latching disabled (default)
• 1 = Latching enabled
Ch[x].Disable BOOL Disables the channel. • 0 = Enabled (default)
• 1 = Disabled
Ch[x]. TempEnglish BOOL Used with the TempAbsolute tag for the same channel to
determine the temperature units for the channel when
linearizing (non-zero sensor type).
• 0 = Standard (default)
• 1 = English
IMPORTANT: The combination of
this value with that of the
TempAbsolute tag value determine
the temperature unit used.
For example, if TempEnglish = 0
and TempAbsolute = 0, the
combination is 00.
Thus, Celsius units are used.
The following combinations are
possible:
• 00 = Celsius
• 01 = Fahrenheit
• 10 = Kelvin
• 11 = Rankine
Ch[x].TempAbsolute BOOL Used with the TempEnglish tag for the same channel to
determine the temperature units for the channel when
linearizing (non-zero sensor type).
• 0 = Familiar (default)
• 1 = Absolute
IMPORTANT: See the TempEnglish
tag Valid Values description for
more information on using this tag’s
value.
Ch[x].FourWireRTD BOOL Sets what type of RTD, that is, 3-wire or 4-wire, is
connected to the channel.
• 0 = 3-wire RTD (default)
• 1 = 4-wire RTD
Ch[x].SynchronizeSampling BOOL Determines if the sampling of the channel is synchronized
with other channels configured for synchronized
sampling.
• 0 = Not synchronized (default)
• 1 = Synchronized
Ch[x].TenOhmOffset INT Specific offset for 10 Ohm Copper Sensor Type.
Value is measured in Hundredths of Ω with 2 implied
decimal places.
-100…100 in hundredths of Ω
0 = default
