Self-diagnostic

Stores the self-diagnosed error number in BIN. (Refer

22

error

to page 22 for the error codes.)

 

 

 

 

 

 

 

 

 

Operation error

Stores the step number in BIN, at which an instruction

 

execution error occurred. After that, data is updated

step

each time operation error occurs.

 

 

 

 

 

 

 

 

 

 

 

 

Stores the step number in BIN, at which an instruction

 

Operation error

error occurred. Since data is stored into D9011 when

step

M9011 turns from off to on, D9011 data is not updated

 

 

unless M9011 is cleared by the user program.

Minimum scan

Stores the scan time at every END that is smaller than

BIN.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Maximum scan

Stores the scan time at every END that is greater than

 

time

D9019 data, i.e. stores the maximum scan time in

(10ms units)

BIN.
