Error Status
1. Description of setting
If an error is detected on 4DA-ADP, the error status data will be stored in the corresponding special data
register.
The following table shows the special data registers that store the error status data:
• FX
3U
, FX
3UC
 Series PLC
• FX
3G 
Series PLC
Check the ON/OFF status of each bit of the error status data register to check the description of the error.
Errors are assigned to the bits as shown in the following table. Create a program to detect errors.
*1.
The 4DA-ADP is supported from June, 2009 and later.
For using the 4DA-ADP, it is necessary to use a main unit whose version supports this function.
For the applicability of each combination of 4DA-ADP and main unit, refer to Section 6.5.
