1. The alarm text extension is inserted into the alarm text file (e.g. alp_gr.com) as follows:
700000 0 0 "Attention: %1<DUMMY> failed!"
The %1 parameter evaluates the first parameter transferred from the PLC and is linked to
the "dummy_gr.com" file with <DUMMY>. This was done during the previous steps (the
entry in MBDDE.INI).
2. Calling the auxiliary value from the PLC via SFC17/18:
CALL SFC 18
SIG :=
ID :=
EV_ID :=
SD :=
RET_VAL:=
