Input Data
Output Data
Note Data can be allocated using other data combinations if an OMRON CS/CJ-
series Master Unit is used. The settings are made in the Master Unit.
Selecting
Temperature Data
The data can be selected from six calculated values to allocate as Tempera-
ture Data 1. Select one of the following: temperature input value, peak value,
bottom value, top value, valley value, or rate of change. The selected data is
allocated in the Master Unit alone or in combination with Status Flags.
Using the CX-Integrator
1,2,3... 1. Turn ON the power supply to the Temperature Input Unit.
2. Double-click the icon of the Temperature Input Unit to be set in the Network
Configuration Window or right-click the icon and select
Parameter - Edit .
The Configuration Window will be displayed.
3. Click the table for the input where the temperature data is to be selected
and select the data to allocated in the
Allocate Temperature Data 1 Field.
Input data Description
Temperature Data 1
Normal Display: 4 input words
(8 bytes)
1/100 Display: 8 input words
(16 bytes)
• Allocated to monitor temperature data.
• Select one of the following values: temperature
input value, peak value, bottom value, top value,
valley value, or rate of change. (The temperature
input value is allocated by default.)
Note The comparator function can be used with the
value allocated as Temperature Data 1.
Top/Valley Detection Timing
Flags (1 input word (2 bytes)) Top/Valley Detection Timing Flags are allocated to
one input word. These flags are allocated together
with the top/valley value and used to time the reading
of value held as the top or valley value.
Temperature Status Flags (2
input words (4 bytes)) These words contain the bits for the Comparator
Result Flag, Top/Valley Detection Timing Flag, and
Disconnected Line Detection Flag. The function of
each bit is as follows:
• Comparator Result Flags:
Allow control of the judgement results even if tem-
perature input value is not allocated.
• Top/Valley Detection Timing Flags:
These flags are allocated together with the top/val-
ley value and used to time the reading of value held
as the top or valley value.
• Off-wire Detection Flags:
Disconnections can be detected even when the tem-
perature input value is not allocated.
Temperature Data 1 + Top/
Valley Detection Timing Flags
Normal Display: 5 input words
(10 bytes)
1/100 Display: 9 input words
(18 bytes)
These words contain Temperature Data 1 followed by
the Top/Valley Detection Timing Flags.
Output data Description
Hold Flags
1 output word (2 bytes)
These flags are used with the hold functions (peak,
bottom, top, and valley) to control the execution tim-
ing of hold functions from the Master Unit.
