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