[Design Precautions]

WARNING" and " CAUTION".

CAUTION" may lead to

WARNING

• Install a safety circuit external to the programmable controller that keeps the entire system safe

even when there are problems with the external power supply or the programmable controller. Otherwise, trouble could result from erroneous output or erroneous operation. (1) The status of analog output changes depending on the setting of various functions that

control the analog output. Take sufficient caution when setting for those functions. For details of analog output status, refer to Section 3.4.5 ”Combinations of various functions”

(2) Normal output may not be obtained due to malfunctions of output elements or the internal

circuits. So build an external monitoring circuit that will monitor any single outputs that could cause serious trouble.

CAUTION

• Do not bunch the control wires or communication cables with the main circuit or power wires, or

install them close to each other. They should be installed 100mm(3.94inch) or more from each other. Not doing so could result in noise that would cause erroneous operation.

• At power ON/OFF, voltage or current may instantaneously be output from the output terminal of

this module. In such case, wait until the analog output becomes stable to start controlling the external device.

1. OVERVIEW MELSEC-A

1. OVERVIEW

1.1 Features

This user's manual describes the specification and handling of AJ65BT-64DAV digital analog voltage conversion module (abbreviated as AJ65BT-64DAV from here on) and AJ65BT-64DAI digital analog current conversion module (abbreviated as AJ65BT-64DAI from here on), which is used as the remote device station for the CC-Link system.

(1) AJ65BT-64DAV

This is a module which converts the digital values (16-bit encoded binary value) set in the programmable controller CPU to analog values (-10V to 0V to 10V voltage), and performs an external output to four channels.

(2) AJ65BT-64DAI

This is a module which converts the digital values (16-bit encoded binary value) set in the programmable controller CPU to analog values (4mA to 20mA current), and performs an external output to four channels.

In this manual, the name which refers to both AJ65BT-64DAV and AJ65BT-64DAI is abbreviated as “AJ65BT-64DAV/DAI.”

The AJ65BT-64DAV/DAI has the following features:

(1) One module can provide four channels of D/A conversion.

The AJ65BT-64DAV/DAI can produce output of analog values (voltage/current) to four external devices.

(2) The analog-output enable/prohibit setting is possible for each channel.

The sequence program can specify whether to enable or prohibit analog output to the external devices after the D/A conversion for each channel. Analog output from the channel where the analog output is prohibited will be 0V or 0mA.

(3) You can make the analog output hold/clear setting at a programmable controller CPU stop or link

error occurrence (all channels batch). Using the HOLD/CLR terminal, you can select whether to hold or clear the analog output at the instant the programmable controller CPU is set to a STOP status or a link error occurs.

(4) Offset and gain setting

When a fine I/O conversion characteristic is required, the offset and gain setting of each channel can be set without a volume control, enabling to modify the I/O conversion characteristic as desired.

3.4 Various Functions to Control the Analog Output

Various functions to control the analog output of the AJ65BT-64DAV/DAI are explained.

3.4.1 Function to specify hold or clear of the analog output when the programmable controller CPU is in the STOP status (HOLD/CLEAR setting)

Using this function, the HLD/CLR terminal on the module front panel can be used to set whether to retain or clear (i.e. to output the offset) the analog output value immediately before the programmable controller CPU enters the STOP status or before the AJ65BT-64DAV/DAI stops the D/A conversion due to an error. All channels are set simultaneously. (Including a time when link communications are shut off)

3.4.2 Function to specify executing or not executing the D/A conversion processing (Analog output enable/disable flag)

Using this function, whether to output the D/A conversion value or the offset value can be selected for each channel by turning on or off the Analog output enable/disable flag from the programmable controller program. However, the D/A conversion time (conversion speed) is constant regardless of the setting of the Analog output enable/disable flag.

ON: D/A conversion value OFF: Offset value

3.4.3 Function to specify enabling or prohibiting of the analog value external output (Analog output enable/prohibit setting)

Using this function, whether to enable or prohibit the external output of the analog signal can be specified for each channel by writing "0" or "1" to the remote register's address from the programmable controller program.

1: 0V/0mA 0: D/A conversion value or offset value

3.4.4 Offset/gain setting

When a fine I/O conversion characteristic is required, the I/O conversion characteristics can be modified arbitrarily by setting the offset and gain of each channel without a volume control, after entering the test mode by short-circuiting the test mode terminal. When it is not necessary, turning on the RYn4, which is the I/O signal to the master station, selects the factory-configured offset and gain values.

Factory-configured values:

AJ65BT-64DAV........ Offset value 0V, Gain value 10V

AJ65BT-64DAI ......... Offset value 4mA, Gain value 20mA

3.4.5 Combinations of various functions

By combining the functions explained above, the analog output when the programmable controller CPU is in the RUN status and when a module error occurs can be set as desired, as shown in Table

3.3.

Select each function depending on the analog output status of your choice.

After the power is turned on or after the hardware reset, the initial data processing request flag is turned on by the AJ65BT-64DAV/DAI in order to request the initial data setting. It is turned off when the initial data setting is complete (i.e. initial data processing complete flag RY(n+1)8 is turned on).

When there is an initial data setting request (i.e. RY(n+1)9 is turned on), it is turned on by the initial data setting completion. When the initial data setting request flag is turned off after the initial data setting completion, the initial data setting complete flag is also turned off.

This is turned on when an error other than the WDT error occurs on the AJ65BT-64DAV/DAI.

This is turned on when the initial data setting is complete and the AJ65BT-64DAV/DAI is in the READY status, after the power is turned on or after the hardware reset. It is turned off during the test mode. (This is used to interlock the read and write from the master module.)

These are the analog value output enable signals for channels 1 through 4. The analog output value from the corresponding channel is enabled when turned on. Turn it off to prohibit the output of the analog value.

"User settings" or "factory settings" of the offset and gain values are selected by switching the RYn4. To select the factory setting, keep the RYn4 set to on.

After the power is turned on or after the hardware reset, the initial data processing is executed by the initial data processing request, and this flag is turned on after the processing is completed.

Turn this on to set or modify the initial data.

When the error reset request flag (RY(n+1)A) is turned on, the error status flag (RX(n+1)A) is turned off and the error code of the remote register write area is cleared (0000

Precautions when wiring the AJ65BT-64DAV/DAI and how to wire to the external devices are explained.

4.7.1 Precautions when wiring

To obtain maximum performance from the functions of AJ65BT-64DAV/DAI and improve the system reliability, an external wiring with high durability against noise is required. The precautions performing external wiring for the AJ65BT-64DAV/DAI are shown below: (1) Use separate cables for the AC and AJ65BT-64DAV/DAI external input signals, in order not to be

affected by the AC side surge or conductivity.

(2) Do not bunch the control wires or load cables from other than the programmable controller with

the wires to the module, or install them close to each other. Doing this makes the wiring easy to accept the noise, surge or induction effects.

(3) Perform a one-point grounding for the shielded line or the shield of the shielded cable.

4.7.2 Wiring between the AJ65BT-64DAV/DAI and external devices

(1) Wiring example of the AJ65BT-64DAV and external devices is shown in Figure 4.1.

Note that the master module can register the initialization procedure of only the specified station out of the multiple remote device stations. The master module supporting this function is the QJ61BT11N which serial No's first 5 digits is 08032 or later. Fro details, refer to the CC-Link System Master/Local Module User's Manual, "CHAPTER 4 FUNCTIONS"

*2: Before the communication program is executed with remote device stations, the program

enclosed by the dotted line 1) enables the initial setting by using the SB0D (remote device station initialization procedure registration instruction) and SB5F (completion status of remote device station initialization procedure). Initialization processing can’t be made only by the parameter setting of GX Developer.

*3: The program enclosed by the dotted line 2) is necessary only when the initial settings are
