D.1 RESTRICTIONS RELATED TO ETHERNET AND DATA
SERVER BOARDS
There are restrictions on the number of sockets for the Ethernet board
and data server board. The socket is a logical communication line used
to communicate with the host computer.
The number of sockets that can be used is limited to within 24. An
attempt to communicate using more than 24 sockets ends in an error.
The number of sockets used by each function is as follows:
FACTOLINK function
One socket is consumed when the optional FACTOLINK function is
set up.
DNC1/Ethernet function
FOCAS1/Ethernet function
Three sockets are consumed when the optional DNC1/Ethernet or
FOCAS1/Ethernet function is set up. Two more sockets are consumed
by each application connected to the CNC.
Data server function
Six sockets are consumed when the optional data server function is set
up. In the FTP or buffer mode, two more sockets are consumed for
each CNC system.
NOTE
Basically, sockets are used only when
communication is taking place. In some cases,
therefore, communication is possible even if the total
of the consumed sockets exceeds the maximum
permitted number. In this case, communication may
become impossible abruptly, however.
