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)
Byte Variable (1 bit) Variable (16 bit) Variable (32 bit)

Note!
Avoid simultaneous overwriting via different varianle types to ensure data
consistency.
If you want to describe e.g. the bytes 1 and 2, either use only the variable
CAN3_dnOutD1_p, only the variable CAN3_nOutW1_a or only the variables
CAN3_bFDO0_b ... CAN3_bFDO15_b!
