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:
Table 12-66Reference Junction Parameters for the IM151-1 STANDARD, IM151-1 FO STANDARD
Parameters
Module Value Range Explanation
Reference junction
slot 1 to reference
junction slot 8
IM151-1
STANDARD/
IM151-1 FO
STANDARD
None, 2 to 63 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).
Reference junction
input 1 to reference
junction input 8
IM151-1
STANDARD/
IM151-1 FO
STANDARD
RTD at
channel 0
RTD at
channel 1
This parameter allows you to set
the channel (0/1) for measuring
the reference temperature
(calculation of the compensation
value) for the assigned slot.
Reference junction E0
and reference
junction E1
2AI TC None, RTD This parameter allows you to
enable the use of the reference
junction.
Reference junction
number
2AI TC 1 to 8 This parameter allows you to
assign the reference junction (1
to 8) that contains the reference
temperature (compensation
value).
