8-2. 2-Wire High-Speed Bi-Directional Serial Interface SI/F II
SI/F II is the 2-wire high-speed bi-directional serial interface for operating multiple of
F805AT-BCs in master/slave mode.
Connection
SI/F II is a 2-wire interface extendable up to about 300 m and capable of networking up
to eight F805AT-BCs. It is a polar-interface: terminals with the same polarity must be
connected.
ID number
SI/F II is capable of connecting up to eight F805AT-BCs (up to four masters) in the
same network. F805AT-BCs can be grouped together (max. four groups) based on the
ID number: each group must have a unique ID number.
This scheme allows F805AT-BCs with different ID number to be linked in the same
network, contributing to reduce wiring cost and simplify maintenance.

The slave device, if it is not properly connected to its master, may generate
“Master error” at a regular interval. This message is automatically removed
once it establishes proper communication.
