[Date of Issue] Apr., '06
[Relevant Models] Q64RD/Q64RD-G/Q64TD/Q64TDV-GH
Thank you for your continued support of Mitsubishi programmable logic controllers, MELSEC-Q series.
New function, "Conversion setting for disconnection detection" has been added to the
Q64RD/Q64RD-G/Q64TD/Q64TDV-GH. Also, "Moving average" and "Primary delay filter" have enhanced the
functionality of the Q64RD.
Refer to Section 1.1 for a list of the functions added, Section 1.2 for the serial No. and product information of supported
modules, and Section 1.3 for relevant models. When replacing an old model by an upgraded one, modification of the existing
programs may be required. Then, modify the programs referring to Section 1.4 "Changes arising from addition of the
conversion setting for disconnection detection" and Section 1.5 "Compatibility with old models".

This section explains the new functions.
1.1 New functions
The following table lists the new functions.
Item
Conversion setting for
disconnection detection
Description
The corresponding set value is stored in the CH measured temperature
buffer area, when disconnection detection occurs. The actual corresponding
value can be selected from the following, "Up scale (each range’s upper
limit value +5%)", "Down scale (each range’s lower limit value -5%)",
"Given value" or "Value immediately before disconnection".
Moving average
Digital output values that are measured for the specified number of times
are averaged at sampling time intervals.
Primary delay filter
By setting a preset time constant, digital output values are less volatile
(smoothed).

[Title] New additional functions for the Q64RD/Q64RD-G
/Q64TD/Q64TDV-GH
[Date of Issue] Apr., '06
[Relevant Models] Q64RD/Q64RD-G/Q64TD/Q64TDV-GH
The background of the changes is explained below.
(1) The Up and Down scale functions have been added, by which a measured temperature value is changed to the
highest or lowest value in the case of cable disconnection.
To utilize these functions, the measured temperature value needs to be read from the sequence program when
disconnection is detected.
Therefore, the previous specifications have been changed so that the conversion completion flag (XnE) and
conversion completion flag (buffer memory address 10: Un\G10), which will be used as interlocks in read
programs, do not turn off in such application.
(2) In older models, the conversion completion flag (XnE) turns off when a channel is disconnected.
If the conversion completion flag (XnE) is used as an interlock in a read program, measured temperature values
of other channels are unable to be read.
In the upgraded models, the conversion completion flag (XnE) does not turn off at the time of disconnection, and
thereby measured temperature values of other channels can be read.
(3) In other analog modules, signals indicating conversion completion (equivalent to XnE and Un\G10) do not turn
off when cable disconnection is detected. Therefore, the relevant upgraded models have been designed to behave
the same as those analog modules.
1.5 Compatibility with old models
When replacing an old model with an upgraded one (See Section 1.2 (1)), please pay attention to the following and
modify existing programs as necessary.
• The default for the additional function, conversion setting for disconnection detection, is "Value immediately
before detection" which is the same as for old models.
• There is compatibility within the allowable setting range of the Averaging processing specification (buffer
memory address 9: Un\G9).
Note that, in the upgraded models, the conversion completion flag (XnE) and conversion completion flag (buffer
memory address 10: Un\G10) do not turn off when disconnection is detected.
Modifying a program with reference to Section 2.1.1 enables to use both the old and upgraded models. If the
conversion completion flag (XnE) is not used as an interlock for disconnection detection, both the old and upgraded
models can be used without program modification.

2. Details of the new functions
The details of the new functions are explained in this section.
2.1 Conversion setting for disconnection detection (Q64RD/Q64RD-G/Q64TD/Q64TDV-GH)
(1) The corresponding set value is stored in the CH measured temperature buffer area, when disconnection
detection occurs. The actual corresponding value can be selected from the following, "Up scale (each range’s
upper limit value +5%)", "Down scale (each range’s lower limit value -5%), "Given value" or "Value
immediately before disconnection".
(2) This function can be utilized only for channels where temperature conversion is enabled.
(3) When "Up scale" or "Down scale" is set, an Up scale value (each range’s upper limit value + 5%) or a Down scale
value (each range’s lower limit value - 5%) of the individual range is stored respectively.

2.1.1 Precautions when replacing old models
(1) Disconnection detection
Use the disconnection detection signal (XnC) and disconnection detection flag (buffer memory address 49:
Un\G49) for disconnection detection (Refer to Figure A).
When a program is created as the Figure A, both the old and upgraded models (Refer to Section 1.2 (1).) can be
used without program modification.
Figure A
Note that, in the upgraded models (Refer to Section 1.2 (1).), the conversion completion flag (XnE) and
conversion completion flag (buffer memory address 10: Un\G10) do not turn off when disconnection is detected.
Moreover, when the conversion completion flag (XnE) is used for disconnection detection as the Figure B, it
does not turn off when disconnection is detected. Therefore, the detection will not be correctly performed.
Since the conversion completion flag (XnE) and conversion completion flag (buffer memory address 10:
Un\G10) are not fault finding signals, modify the program so that the disconnection detection signal (XnC) and
disconnection detection flag (buffer memory address 49: Un\G49) are included.
Modifying the program as the Figure A enables to use both the old and upgraded models.

(2) Resetting the disconnection detection signal (XnC)/disconnection detection flag (buffer memory address
49: Un\G49)
After confirming the disconnection has been recovered, reset the disconnection detection signal
(XnC)/disconnection detection flag (buffer memory address 49: Un\G49) using an external signal.
When they have been reset using an external signal, both the old and upgraded models (Refer to Section 1.2 (1).)
can be used without program modification.
When using the upgraded model, the conversion completion flag (XnE) does not turn off in case of disconnection
detection. Accordingly, if the program is for performing the Error Clear Request (YnF) at the start-up of
conversion completion flag (XnE) as the Figure C, the program does not operate normally.
Create the program as the Figure D to automatically clear the disconnection detection signal (XnC) and
disconnection detection flag (buffer memory address 49: Un\G49) on the sequence program of both the old and
upgraded models.
Figure C
Since not turning off in case of disconnection detection,
the conversion completion flag (XnE) does not turn on
when disconnection is recovered
