4.10
Parameter Access Error Detection Function
This function allows parameter access errors to be detected.
• Slave module hardware error (error code: 0D2CH, 0D2DH)
• Parameter access target module ID error (error code: 0D2EH)
• Parameter value error (error code: 0D2FH)
• Parameter access error (error code: 0D30H)
• Slave module status error (error code: 0D31H)
• Same ID used error (error code: 0D90H)
• No ID setting error (error code: 0D91H)
• New ID error (error code: 0D92H)
How to check the parameter access error status
The following table lists parameter access error statuses.
*1 If multiple errors occur simultaneously, the latest error is displayed.
*2 If an error occurs in parameter access, data are stored in 'Number of the error IDs' (Un\G8192) and 'Error ID information storage area
(Un\G8193 to Un\G8320)'.
How to recover from the parameter access error status
How to recover from the parameter access error status is as follows.
■
Slave module hardware error
Take measures such as those against noise to remove factors causing errors. Then power off and on the AnyWireASLINK
system or turn on and off 'Error flag clear command' (Un\G27 b0).
■ Parameter access target module ID error, parameter value error
Remove factors causing errors (for example, parameter access program). Then power off and on the AnyWireASLINK system
or turn on and off 'Error flag clear command' (Un\G27 b0).
Error description Status when an error occurred
Status information Buffer memory
Slave module hardware error 'Slave module alarm signal' (Un\G28 b8) turns on. ■ 'Latest error code storage area' (Un\G10256)
The error code is stored.
*1
■ 'Latest error ID storage area' (Un\G10257)
The IDs corresponding to the error codes are stored.
■ 'Number of the alarm IDs' (Un\G9984)
*2
The number of IDs relevant to alarm occurrence is stored.
■ 'Alarm ID information storage area' (Un\G9985 to
Un\G10112)
*2
The IDs relevant to alarm occurrence are stored.
