9. REAL & VIRTUAL MODE SWITCHING AND STOP/RESTART
9 − 3
(2) Output module check
(a) The items shown in Table 9.2 below are checked to determine the output
module status.
If an error is found, switching to the VIRTUAL mode will not occur, and the
corresponding system cannot be started. When an error exists, switch back
to the REAL mode and correct the error cause, then switch to the VIRTUAL
mode again.
(b) When an error is found, the corresponding output module's error detection
signal (M2407+20n) will switch ON, and the error code will be stored in the
minor/major error code register.
