Description
Imports temperature data.
Sets whether to enable/disable a
conversion per channel.
Detects a disconnection of the connected
thermocouple of each channel.
Stores imported temperature data in the
buffer memory.
Sets an input type for each channel.
Outputs a warning when the temperature
exceeds the set temperature range.
Processes the detected temperature by
specified method.
Converts a measured temperature value
into a percent value (%) in set width.
Sets whether the cold junction
compensation using the Pt100 attached to
the terminal is performed or not.
Performs linear correction by individually
compensating any given 2 points (offset
value/gain value) within the effective range.
For all input ranges, the function allows
compensating the temperature
measurement value by part of the
compensation value the errors
compensation value.
Replaces a module without stopping the
system.
A616TD Q64TD Precautions for replacement
On Q64TD, the channel set
conversion enable automatically
performs the disconnection
detection.
For the Q64TD, this function is
set with the intelligent function
module switch setting.

Q64TD.
Replaceable modules during
- online are the Process CPU and
the Redundant CPU.
