User data
The first 4 bytes of the 8 bytes user data to be sent can be written via several variables of
different data types. According to requirements, data can therefore be transferred from
the PLC program as
ƒ binary information (1 bit)
ƒ status word/quasi−analog value (16 bit)
ƒ angle information (32 bit)
Note!
Avoid simultaneous overwriting via different variable types to ensure data
consistency.
Thus, bytes 1 and 2 should only be overwritten by
ƒ variable AIF3_dnOutD1_p,
ƒ variable AIF3_nOutW1_a or
ƒ variables AIF3_bFDO0_b ... AIF3_bFDO15_b.
