Configurable Parameters
The default parameters of the Thermocouple Input module can be used in many
applications. The module can be software-configured when it is installed in a
VersaMax PLC system, or an I/O Station controlled by a NIU that is version 2.0
or above.

Description
Word length of the module's analog input
data.
Starting offset for the module's analog input
data.
Word length of the module's optional
Reference Compensation data.
Starting offset for the module's optional
Reference Compensation data.
Specifies the line frequency. The module
uses this data to control the sampling rate.
Determines whether or not the module will
suppress Open Thermocouple diagnostics on
the input data.
Specifies if the channel should return data
and alarms. If a channel is "inactive" space is
still allocated for it.
Specifies how the module will report input
values
The type of thermocouple present on each
channel.
For millivolt inputs only, the range for each
channel in millivolts.
Specifies how or whether the channel will
perform Cold Junction compensation.
The low alarm limit for the channel, in
engineering units.
The high alarm limit for the channel, in
engineering units.
Specifies a reference value, in engineering
units, if the RJ Type, Fixed, is selected.
Specifies optional amount to be added to
compensated and linearized input value
when a Conversion Type in degrees has
been configured.
Specifies analog input returned upon error
(including open circuit errors).
