Device Addressing and Message Routing 31007492 23
Here are examples of routing between peer, master, and slave devices.
From To Routing Path
CPU A (Primary) Slave A 5 2 0 0 0
50 5 3 50 0 0
CPU C 25 2 0 0 0
SA85 (Task 1) 25 30 1 0 0
Slave B 25 4 2 0 0
200 25 4 3 200 0
CPU C SA85 (Task 2) 30 2 0 0 0
Slave B 4 2 0 0 0
200 4 3 200 0 0
CPU A (Primary) 24 8 0 0 0
CPU B (Standby) 24 40 0 0 0
100 24 5 3 100 0
SA85 Slave B 4 2 0 0 0
150 4 3 150 0 0
CPU C 2 0 0 0 0
CPU A (Primary) 24 8 0 0 0
50 24 5 3 50 0
If Masters A, B, and C are programming panels such as the Modicon
P230, they can attach to various devices using Direct, Implicit, or MUX
addressing, or mapped routing:
From To Address Routing Method
Master A CPU A (Primary) 8 Attach Direct 8 0 0 0 0
Slave A 72 Attach MUX Internal Path
CPU C 252 Attach Implicit 252/10 = 25 2 0 0 0
50 50 Attach Mapped 0 3 50 0 0
200 200 Attach Mapped 25 4 3 200 0
Master B CPU C 2 Attach Direct 2 0 0 0 0
Slave B 72 Attach MUX Internal Path
CPU A (Primary) 248 Attach Implicit 248/10 = 24 8 0 0 0
200 200 Attach Mapped 0 3 200 0 0
50 100 Attach Mapped 24 5 3 50 0
Master C CPU A (Primary) 248 Attach Implicit 248/10 = 24 8 0 0 0
CPU B (Standby) 71 Attach Mapped 24 40 0 0 0
Slave A 72 Attach Mapped 24 5 2 0 0
Slave B 73 Attach Mapped 4 2 0 0 0
150 74 Attach Mapped 4 3 150 0 0
