FANUC Series16i /18i /21i
FOCAS1/HSSB PORT2 function
A-77931E
1999.11.05 E.Genma H.Kozai
1. Outline
In the past, it was possible to attach only one HSSB board. But by this function, it is possible to connect 2
personal computers by attaching 2 HSSB boards to one CNC. On the each personal computer, it is
possible to read and write the various CNC data by using data window libraries, which are provided by
FANUC.
This specification describes the setting method, functions and notes of 2nd HSSB board on the hardware
with the 2 HSSB boards.
2. Setting method of 2nd HSSB board
It is possible to use the same specification’s HSSB board on 1st and 2nd board. In case of using 2nd
HSSB board, set the rotary switch on HSSB board to “6” for 2nd board.
3. Functions on 2nd HSSB board
