User data
The first 4 bytes from the 8 bytes of received user data are assigned to several variables of
different data types. According to requirements, they thus can be evaluated by the PLC
program as:
ƒ binary information (1 bit)
ƒ quasi−analog value (16 bit)
ƒ angle information (32 bit)
Byte Variable (1 bit) Variable (16 bit) Variable (32 bit)
