Message Routing
890 USE 100 00
195
The routing path pointed to by the Modbus address is applied to the
message. Each path is five bytes in length:
4x Free-Running Timer
70 4x + 1 Routing Path 1, byte 1
4x + 2 Routing Path 1, byte 2
4x + 3 Routing Path 1, byte 3
4x + 4 Routing Path 1, byte 4
4x + 5 Routing Path 1, byte 5
71 4x + 6 Routing Path 2, byte 1
. . . . . .
4x + 50 Routing Path 10, byte 5
80 ... 255
If the address is in the range 80 ... 255 (Implicit Attach Address), it will
be divided by 10. The quotient and remainder of the division will
become the first two bytes of the five byte routing path. The remaining
three bytes of the routing path will always be zeros. This addressing
method allows two levels of addressing across Modbus Plus networks.
