(70)CH Temperature process value (PV) for input with another analog module
(Un\G689 to Un\G692)
Digital input value of the current/voltage converted in another analog module (such as A/D conversion module)
connected to the system can be used as a temperature process value (PV).
Store digital input values of current/voltage converted by another analog module (such as A/D conversion
module) in this area.
For details, refer to the following.
Page 221, Section 4.16 (1)
If a stored value is out of the set input range, the value to be used in control is fixed to the upper limit value or the lower limit
value of the input range.
(71)CH Temperature conversion setting (Un\G695 to Un\G697)
In the heating-cooling control (normal mode) or the mix control (normal mode), only the temperature
measurement can be performed using temperature input terminals of unused channels.
The following table lists the settable buffer memory addresses for each control mode selection.
When the combination of the control mode and the buffer memory address is not the setting target in the above
list, the combination is invalid even if it is set.
For details on the temperature conversion function (using unused channels), refer to the following.
Page 262, Section 4.27
(a) Setting range
• 0: Not use
• 1: Use
(b) Default value
The default values are set to Not use (0) in all channels.
● When this setting is set from Not use (0) to Use (1), after completion of the first temperature conversion, Temperature
conversion completion flag (Un\G786) is set to First temperature conversion completed (1
H
). Before referring to the
temperature process value (PV) of each channel, check Temperature conversion completion flag (Un\G786) has been set
to First temperature conversion completed (1
H
).
● When the following control mode is selected, this setting is invalid.
• Standard control
• Heating-cooling control (expanded mode)
• Mix control (expanded mode)
