User data
The first 4 bytes of the 8 bytes of user data to be sent can be written to via several variables of different
data types at the same time. Data can therefore be transferred by the PLC program as
·
binary information (1 bit)
·
quasi−analog value (16 bits)
·
angle information (32 bits)
according to the requirements.

Tip!
Avoid simultaneous overwriting via different variable types to ensure data consistency.
·
Thus bytes 1 and 2 should only be written to
– by the variable AIF2_dnOutD1_p,
– by the variable AIF2_nOutW1_a or
– by the variables AIF2_bFDO0_b ... AIF2_bFDO15_b.
