Analog Electronic Modules
Parameter Assignment of the Reference Junction for the 2AI TC and the
Interface Module
You set the reference junctions for the 2AI TC electronic modules by means of the
following parameters:

Explanation
This parameter allows you to
assign up to 8 slots (none, 2 to
63) where the channels for
measuring the reference
temperature are found
(calculation of the compensation
value).
This parameter allows you to set
the channel (0/1) for measuring
the reference temperature
(calculation of the compensation
value) for the assigned slot.
This parameter allows you to
enable the use of the reference
junction.
This parameter allows you to
assign the reference junction (1
to 8) that contains the reference
temperature (compensation
value).
