Example of Assigning Parameters of Reference Junctions
Analog Electronic Modules
Explanation
This parameter allows you to
assign a slot (none, 2 to 12 or 2
to 63) where the channel for
measuring the reference
temperature is located
(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)
that contains the reference
temperature (compensation
value).
