Process data telegram
The process data telegram consists of an
identifier and 8 bytes of user data.
11 Bit 8-byte user data
Identifier Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8
Identifier
Information about the identifier can be found in chapter 2.3.1.
(^ 2-2)
User data
The received 8 bytes of user data are assigned to several variables of a different data type at the same
time and can therefore - as required - be evaluated as
• binary information (1-bit)
• quasi-analog value (16-bit)
• phase-angle information (32-bit)
in the PLC program:
