with a straight line when converting the analog signals (voltage or current input) from
an external source of the programmable controller to digital values.
The offset value is an analog input value (voltage or current) at which the digital output
value is 0.
The gain value is an analog input value (voltage or current) at which the digital output
value is 4000.

3.3.5 Conversion speed
Conversion speed indicates time from channel changing to A/D conversion completion.
Conversion speed per channel of the AJ65SBT-64AD is 1ms.
Due to the data link processing time of the CC-Link system, there is a transmission
delay until the A/D conversion value is read actually.
For the data link processing time, refer to the user's manual for the master module
used.
Example) Data link processing time taken in the asynchronous mode when the master
module is the QJ61BT11 (normal value)

3.4.1 Sampling processing
The A/D conversion is performed successively for the analog input, and the converted
digital output values are stored in the remote register.
The processing time to store the digital output value into the remote register after the
sampling processing differs depending on the number of A/D conversion enabled
channels.
(Processing time)
Number of A/D conversion enabled channels) 1 (ms)
Maximum conversion speed
[Example] When three channels, channels 1, 2, and 3 are enabled for conversion:
3×1 = 3 (ms)
3.4.2 Moving average processing
The specified count of digital output values imported per sampling time are averaged to
find a value, which is then stored into the remote register.
Since average processing is performed with data shifted per sampling, the most recent
digital output value is available.
Average processing can be performed without changing the conversion speed.
Use moving average processing count setting (address RWwm+2) to set the number
of moving average processing.
The count can be selected from among four types: 4, 8, 16 and 32 times.

4.8 Wiring
This section provides the instructions for wiring the AJ65SBT-64AD and its wiring with
external equipment.
4.8.1 Wiring precautions
To obtain maximum performance from the functions of AJ65SBT-64AD and improve
the system reliability, an external wiring with high durability against noise is required.
The precautions when performing external wiring are as follows:
(1)
Use separate cables for the AC and AJ65SBT-64AD external input signals, in
order not to be affected by the AC side surge or conductivity.
(2)
Do not bundle or place with load carrying wires other than the main circuit line,
high voltage line or programmable controller. Noises, surges, or conductivity may
affect the system.
(3)
Place a one-point grounding on the programmable controller side for the
shielded line or shielded cable. However, depending on the external noise
conditions, it may be better have a grounding externally.

For the current input, be sure to connect the (V+) and (I+) terminals.
When noise or ripple occurs with the external cable, connect a condenser with
about 0.1 to 0.47µF (25V or higher voltage-resistant product) between the terminal
V and COM.
*5 Always perform grounding for FG1. When there is a lot of noise, it may be better
ground AG as well.
If the grounding wiring (grounding yes/no) is changed after the offset and gain are
set, perform the setting of the offset/gain values again.

SETUP AND PREPARATION BEFORE OPERATION
MELSEC-A
POINT
 A/D conversion values are fluctuated by self-heating within approx. 30 minutes
after power is turned ON.
 In an unused channel, if terminals remain open, an erratic digital value may be output.
To prevent this, take any of the following measures.
1. Select Prohibit in the A/D conversion enable/prohibit setting for the unused channel.
Note that changing the setting from Enable to Prohibit will reduce the sampling cycle.
2. Short-circuit the input terminals (terminal V+ and COM) of the unused channel.
3. Connect the AG terminal to the GND terminal of the external device.
4.9 Maintenance and Inspection
There are no special inspection items for the AJ65SBT-64AD module, but follow the
inspections items describes in the programmable controller CPU User's Manual so that
the system can always be used in the best condition.

[Corrected program]
RX(m+1)B and RX(n+1)B are remote READY.
RX(m+1)8 and RX(n+1)8 are initial data processing request flags.
Insert the remote READY and initial data processing request flags for all the
stations, to which the remote device station initialization procedure registration
has been made, into the program as an interlock.

The details of the errors which may occur when using the AJ65SBT-64AD and
troubleshooting are described.
6.1 Using the Remote Input Signals to Check Errors
In the AJ65SBT-64AD, occurrence of a write error turns on any of the following remote
input signals.
Device No.
Signal Name
RXn4
CH.1 range error flag
RXn5
CH.2 range error flag
RXn6
CH.3 range error flag
RXn7
CH.4 range error flag
RXnC
Description
Turns on when the value set for input range setting is outside the setting range.
Turns on if all channels are not set to any of "user range settings 1 to 3" at offset/gain
setting (in the test mode).
Turns on if value write failed due to excess of the E2PROM write count over its limit at the
time of offset/gain setting.
If this flag has turned on, this module itself has failed (hardware fault) and therefore this flag
cannot be reset (turned off) by the error reset request flag.
E2PROM write error flag
Turns on when CH.
RX(n+1)A
range error flag (RXn4 to RXn7) or E2PROM write error flag (RXnC)
has turned on.
This flag can be reset (turned off) by turning on the error reset request flag. However, for
the E2PROM write error which cannot be reset, this flag cannot be reset, either.
Error status flag
(1) For the input range error (RXn4 to RXn7), the "RUN" LED flickers at intervals of
0.1s and A/D conversion is not performed on all channels.
(2) For the E2PROM write error (RXnC), power on the AJ65SBT-64AD again.
2
If the E PROM write error (RXnC) turns on after the AJ65SBT-64AD was powered
on, a hardware failure might have occurred. Please consult your local Mitsubishi
representative.

Precautions for replacing the conventional product (AJ65BT64AD) with the AJ65SBT-64AD
In the existing system using the conventional product (AJ65BT-64AD), the
following instructions must be noted when changing the AJ65BT-64AD for the
AJ65SBT-64AD.
(a) Since the AJ65SBT-64AD occupies one station (the AJ65BT-64AD occupies
two stations), the station information setting in the network parameters must
be changed.
(b) As the remote I/O signals and remote register settings are different between
the two models, the program of the conventional model cannot be utilized.
(c) Because of the differences in shape and layout between the terminal blocks,
you cannot use the terminal block of the conventional module as it is.
(d) The offset/gain setting method differs. For details, refer to Section 4.4.
(e) The ways to set the station number and transmission speed setting switches
are different. For details, refer to Section 4.3.
