Error Status Automatic Recovery Function; Slave Information Acquisition At Start-Up Function - Mitsubishi Electric MELSEC iQ-F FX55-ASL-M User Manual

4.11

Error Status Automatic Recovery Function

This function allows for automatic error reset for DP/DN disconnection errors and parameter errors after the error status is
cleared.
(Usually, if an error has occurred, eliminate the error cause, and power off and on the AnyWireASLINK system or turn on and
off 'Error flag clear command' (Un\G27 b0).)
Error that can be automatically recovered
The following shows the errors that can be automatically recovered.
Error code Error description
0CCAH DP/DN disconnection
error
0D30H Parameter access error
*1 The error causes must be eliminated from all the slave modules in which errors have occurred.
*2 If the errors 0CCAH and 0D30H have occurred in one slave module, the causes of both the errors must be eliminated.
Setting method
Set the error status automatic recovery function in "Error status automatic recovery" of "Basic setting". (Page 52 Error
status automatic recovery)

Slave Information Acquisition at Start-up Function

This function allows for automatic acquisition of information of slave modules when the CPU module is reset or the power is
turned off and on.
The slave information acquisition at start-up function eliminates the needs for reading parameters from slave modules.
For the parameters of the slave module stored, refer to the following.
Page 35 Slave Module Parameter Read/Write
Setting method
Set the slave information acquisition at start-up function in "Startup operating mode" of "Basic setting". (Page 52 Startup
operating mode)
Operation at start-up
When communication of the FX5-ASL-M is normally established after the CPU module is reset or the power is turned off and
on, the parameters of all the registered slave modules are read all at once. The read parameters are then stored in the buffer
memory.

4.11 Error Status Automatic Recovery Function
Status when an error occurred
• 'DP/DN disconnection error' (Un\G28 b4) turns on.
• Error ID information is registered in the buffer
memory address. (Page 30 How to check the
transmission cable disconnection status)
• 'Parameter access error' (Un\G28 b10) turns on.
• Error ID information is registered in the buffer
memory address. (Page 32 How to check the
parameter access error status)
Status when an error is cleared
• 'DP/DN disconnection error' (Un\G28 b4) turns off.
• The error ID information registered in the buffer
memory address is cleared. (corresponding ID
*2
only)
• 'Parameter access error' (Un\G28 b10) turns off.
• The error ID information registered in the buffer
memory address is cleared. (corresponding ID
