EV_ID INPUT DWORD I, Q, M, D, L,
constant
Message number (0 not permitted)
EV_ID is only evaluated at the first
call. Subsequently, the message
number used for the first call applies
to every call of SFB 33 with the
corresponding instance DB.
STEP 7 assigns the message number
automatically to ensure consistency of
the message numbers. The message
numbers within a user program must
be unique.
SEVERITY INPUT WORD I, Q, M, D, L,
constant
