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)

Note!
Avoid simultaneous overwriting via different variable types to ensure data
consistency.
E.g., for overwriting bytes 5 and 6, either only use the variable
CAN1_dnOutD1_p, only the variable CAN1_nOutW2_a or only the variables
CAN1_bFDO0_b ... CAN1_bFDO15_b!
