Analog I/O Tag Definitions
The set of tags associated with any module depends on the module type and
the communications format. For each operational mode, integer or floating
point, there are three sets of tags.
• Input
• Output
• Configuration
Integer Mode Tags
The following tables list the tags that are available on ControlLogix analog
modules operating in integer mode.
Integer Input Tags
You can view tags from the Controller Organizer in RSLogix 5000 software.
To access the Tag Editor, right-click Controller Tags and choose Monitor Tags.
IMPORTANT
Each application’s series of tags varies but no input module
application contains any tags that are not listed here.
Integer Input Tags

Modules
Definition
ChannelFaults
INT
All
Collection of individual channel fault bits in one word. Can address individual
channel fault via bit notation: ex. ChannelFaults 3 for channel 3.
Ch0Fault
BOOL
All
Individual channel fault status bit. Indicates a ‘hard’ fault has occurred on the
channel that means: calibration is ongoing; or if an input, an overrange or
underrange condition is present; or if an output, a low or high clamp condition
is occurring. These bits also are set by the controller if communication is lost
with the I/O module.
ModuleFaults
INT
All
Collection of all module level fault bits.
AnalogGroupFault
BOOL
All
Indicates if a channel fault has occurred on any channel.
InGroupFault
BOOL
All inputs
Indicates if a channel fault has occurred on any input channel.
Calibrating
BOOL
All
Indicates if a calibration is currently in progress on any channel.
CalFault
BOOL
All
Status bit indicating if any channel has a ‘bad’ calibration. ‘Bad’ calibration
means the last attempt to calibrate the channel failed with an error.
CJUnderrange
BOOL
1756-IT6I and
1756-IT6I2
Status bit to indicate if the cold junction reading is currently beneath the
lowest detectable temperature of 0.0 °C (32 °F).
