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 5-2 Reference junction parameters
Parameters Module Range of values Explanation
Reference junction slot IM 151 None, 2 to 12
(IM151-1 BASIC)
None, 2 to 13
(IM151-1 COMPACT)
none, 2 to 63
(IM151-1 HIGH
FEATURE,
IM151-1 STANDARD,
IM151-1 FO STANDARD)
A slot with the channel for measuring
the reference temperature (determining
the compensation value) can be
assigned with this parameter.
Reference junction input IM 151 RTD at Channel 0
RTD at Channel 1
This parameter can be used 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
AI TC None, RTD This parameter allows you to enable
the use of the reference junction.
Reference junction number AI TC 1 With this parameter, you assign the
reference junction (1) containing the
reference temperature (compensation
value).
Example of assigning parameters of reference junctions
Setup: For simplification, only RTD and TC modules are shown in the following figure:
