13. Program Support Functions
Modal information variables (#4401 to #4520)
Modal information when control passes to the user macro interrupt program can be known by
reading system variables #4401 to #4520.
The unit specified with a command applies.

The above system variables are available only in the user macro interrupt program. If they are
used in other programs, program error (P241) results.
M code for control of user macro interrupt
The user macro interrupt is controlled by M96 and M97. However, these commands may have
been used for other operation. To be prepared for such case, these command functions can be
assigned to other M codes.
(This invalidates program compatibility.)
User macro interrupt control with alternate M codes is possible by setting the alternate M code in
parameters "#1110 M96_M" and "#1111 M97_M" and by validating the setting by selecting
parameter "#1109 subs_M".
(M codes 03 to 97 except 30 are available for this purpose.)
If the parameter "#1109 subs_M" used to enable the alternate M codes is not selected, the M96
and M97 codes remain effective for user macro interrupt control.
In either case, the M codes for user macro interrupt control are processed internally and not output
to the outside.
