User data
The 8 bytes of 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)
Byte Variable (1 bit) Variable (16 bit) Variable (32 bit)
1, 2 CANaux1_bFDO0_b
...
CANaux1_bFDO15_b
CANaux1_nOutW0_a
3, 4 CANaux1_bFDO16_b
...
CANaux1_bFDO31_b
CANaux1_nOutW1_a
5, 6 CANaux1_bFDO32_b

CANaux1_bFDO47_b
CANaux1_nOutW2_a
CANaux1_dnOutD1_p
7, 8 CANaux1_bFDO48_b

CANaux1_bFDO63_b
CANaux1_nOutW3_a
)
Note!
Avoid simultaneous overwriting via different variable types to ensure data
consistency.
If you want to describe e.g. the bytes 5 and 6, either use only the variable
CANaux1_dnOutD1_p, only the variable CANaux1_nOutW2_a or only the
variables CANaux1_bFDO32_b ... CANaux1_bFDO47_b!
