This chapter describes the troubleshooting methods and error status.

If analog data is not output, or if the proper analog value is not output, check the following items:

• Version number of PLC

• Wiring

• Special devices



C



• Programs



6.1



FX3U-4AD-ADP



• Error status



PLC Version Number Check

• Any versions (from Ver. 1.00 (initial version) to the latest version) of the FX3S Series are compatible.

• Any versions (from Ver. 1.40 (initial version) to the latest version) of the FX3GC Series are compatible.

• Any versions (from Ver. 2.20 (initial version) to the latest version) of the FX3U Series are compatible.



6.2



Wiring Check

Check the following items for wiring:



F



The 4DA-ADP needs driving power. Verify that the power supply line is properly connected. Also check that

the POWER indicator lamp of the 4DA-ADP is on.



2. Analog output line



Special Device Check



G

FX3G-1DA-BD



Use the 2-core twisted shielded pair cable for the analog output line. In addition, be sure to separate the

analog output line from other power lines or inductive lines.

→ For a detailed description of wiring, refer to Chapter 3.

• Check the version number of FX3UC Series. The version number should be 1.20 or later.

→ For a detailed description of the version check method,

refer to A. Common Items Subsection 5.1.2.



D

FX3G-2AD-BD



• Any versions (from Ver. 1.00 (initial version) to the latest version) of the FX3G Series are compatible.



H



Check whether the special devices for the 4DA-ADP are being used correctly:

Verify that the special device for switching the output mode is correctly set.

Turn off the device to set the output mode to the voltage output mode. Turn on the device to set the output

mode to the current output mode.

Program Check

Check the following items for the program:



1. Device for setting specified digital value

Check that different values are not written to this device using other programs.



6.5



Error Status Check

If an error occurs in the 4DA-ADP, the corresponding bit will turn on.

The bit which is turned ON due to the error status is held ON until overwritten to OFF by the program or the

power is cycled.
