15-10 C79000-G7076-C526-01
External access uses only the array element followed by the name of the structure
element.
Note:
The array index is the internal transition number and not the number assigned by
the user.
• G7T[1].TT
• G7T[3].CRIT
"Individual structures" Option
If you have selected the "Individual structures" option, the structures of the
transitions are entered as separate sections in the instance DB, one after the other
as follows:
Structure Name Length in Bytes
<Transition1> 16
...
<Transition2> 16
Internal access uses the transition number or the transition name followed by the
name of the structure element.
This means that the following access is possible in conditions or actions:
• T003.TT
• T017.CRIT
• VALVE_ON.TT
External access uses only the transition name (structure name) followed by the
name of the structure element.
• VALVE_ON.TT
• VALVE_ON.CRIT
