4.4 Wiring

The wiring precautions and examples of module connection are provided below.

4.4.1 Wiring precautions

In order to optimize the functions of the D/A conversion module and ensure system reliability, external wiring that is protected from noise is required. Please observe the following precautions for external wiring:

(1) Use separate cables for alternating current and the external output signal for the

D/A conversion module in order to avoid AC surges and induction effects.

(2) Do not mount the cables close to or bundle them with the main circuit line, a high-

voltage cable or a load cable from other than the PLC. This may increase the effects of noise, surges and induction.

(3) Perform a one-point grounding for shielded lines and the shields of sealed cables.

(4) A solderless terminal with insulating sleeve cannot be used for the terminal block.

Covering the cable- connection portion of the solderless terminal with a marked tube or an insulation tube is recommended.

POINT

When using Q68DAV or Q68DAI, if it is difficult to wire FG terminals due to the limited installation space, use FG terminal L-shaped metal fitting.

5.2 Installing and Uninstalling the Utility Package

See "Method of installing the MELSOFT Series" attached with the utility package regarding the install and uninstall operation for the utility package.

5.2.1 User precautions

The following are precautions when using GX Configurator-DA:

(1) Important safety information

Since GX Configurator-DA is add-in software for GX Developer, read "Safety Precautions" and the basic operati ng procedu res in GX Developer's ope rating manual.

(2) About installation

The GX Configurator-DA is an add-in package for GX Developer Version 4 or later products. Therefore, install GX Configurator-DA in a personal computer in which the GX Developer Version 4 or a later product has been installed.

(3) About display-screen errors while usi ng the i ntelligent function

module utility

There may be cases in which the screen will not properly display while the intelligent function module utility is being used, due to a lack of system resources. If this occurs, close the intelligent function module utility first and then GX Developer (program, comments, etc.) and other applications. Next, restart GX Developer and the intelligent function module utility.

(4) To start the intelligent function module utility

(a) In GX Developer, select "QCPU (Q mode)" for the PC series and specify the

project. If something other than "QCPU (Q mode)" is selected for the PC series, or if the project is not specified, the intelligent function module utility will not start.

(b) Multiple intelligent function module utilities can be started.

However, the [Open file]/[Save file] intelligent function module's parameter operations can only be performed by a single session of the intelligent function module utility. Other intelligent function module utilities can only perform [Monitor/test] operation.

(5) How to switch screens when two or more intell ig ent function

module utilities are started

When two or more intelligent function module utility screens cannot be displayed side by side, use the task bar to change the intelligent function module utility screen so that it is displayed on top of other screens.

Example) Counting the number of parameter settings in the automatic refresh

setting

The number of settings in this one line is counted as one setting. The number of settings is not counted by columns. Add up all the setting items in this setting screen, then add them to the total for the other intelligent function modules to get a grand total.

Is power being supplied?

Confirm that the supply voltage for the power supply module is within the rated range.

Is the capacity of the power supply module adequate?

Calculate the current consumption of the CPU module, I/O module and intelligent function module mounted on the ba se unit to see if the power supply capacity is adequate.

Has a watchdog timer error occurred?

Reset the PLC CPU and verify that it is lit. If the RUN LED does not light even after doing this, the module may be malfunctioning. Contact the nearest distributor or branch office with a description of the problem.

Is the module correctly mounted on the base unit? Check the mounting condition of the module.

7.2.2 When the "ERROR" LED is on or flashing (1) When on

7.2.3 When an analog output value is not output

Check item Action to be taken

Is 24VDC external power supply being supplied?

Verify that 24VDC voltage is being supplied to the external power supply terminals (Q62DA, Q64DA: terminal numbers 16, 17

Q68DAV, Q68DAI: terminal numbers 17, 18). Is there any fault with the analog signal lines such as broken or disconnected line?

Check for any abnormality on the signal lines by doing a

visual check and performing a continuity check. Is the CPU module in the STOP status? Set the CPU module to the RUN status.

Are the offset/gain settings correct?

Verify that the offset/gain settings are correct (see sections

4.6 and 5.6.2).

If the user range setting is being used, switch to a different

default input range and check if D/A conversion is correctly

performed. If it is correctly performed, redo the offset/gain

settings.

Is the output setting range correct?

Verify buffer memory address 20 and 21 (Un\G20 and

Un\G21) in GX Developer monitor. If the output range setting

is incorrect, redo GX Developer intelligent function module

switch settings (see Section 4.5).

Is the resolution mode setting correct?

Check the ON/OFF status of the high resolution mode status

flag (X8) in GX Developer system monitor.

If the resolution mode setting is incorrect, redo the GX

Developer intelligent function module switch setting. (See

Section 4.5.)

Is the D/A conversion enable/disable setting for the channel to be output set to Disable?

Check the D/A conversion enable/disable setting using

buffer memory 0 (Un\G0) in GX Developer monitor and set it

to Enable using the sequence program or utility package

(see Section 3.4).

Is the D/A output enable/disable setting for the channel to be output set to Disable?

Verify ON/OFF for the output enable/disable flags (Y1 to Y8)

in GX Developer monitor.

If the output enable/disable flags are OFF, review the initial

setting for the sequence program or utility package (see

Section 3.3). Is the digital value being written to the channel to be output?

Verify buffer memory addresses 1 to 8 (Un\G1 to Un\G8) in

GX Developer monitor (see Section 3.4).

Has the operating condition setting request (Y9) been executed?

Set the operating condition setting request (Y9) from ON to

OFF from GX Developer and check to see if the analog

output is normal.

If normal analog output is obtained, review the initial setting

for the sequence program or utility package (see Section

3.3).

(1) Incorporation into an existing system

Wiring used for function version A can be incorporated as is in the function version B D/A conversion module.

(2) Program utilization

A program created for function version A can be used as is with the function version B D/A conversion module.

(3) Switch setting for Intelligent function module

Setting of the offset/gain setting mode differs from function version A to function version B. Perform the offset/gain settings after checking the RUN LED flashes in offset/gain setting mode. If the RUN LED does not flash, check to see if the switch 4 setting is correct. (See Section 4.5 for intelligent function module switch settings for function version B).
