Area Block Name Type No. Byte S7 Name
C[1] M MD20090:
SPIND_DEF_MASTER_SPIND
int 20090 1 C1SpindDefMasterSpind
S7 (ALIAS) names have been selected in order to:
• Incorporate the channel designation into the name
and
• Remove the characters [ ], which are not legal in a STEP 7 symbol.
Entry of the name in the S7 SYMBOL table (e.g., NCVAR for DB 120):
Symbol Operand Data type
NCVAR DB120 DB120
File DB120.AWL must be compiled and transferred to the PLC.
Parameterization of FB 2 with instance DB 110:
DATA_BLOCK DB 110 //Unassigned user DB, as instance for
FB 2
FB 2
