NOTE
1 The embedded Ethernet function supports fewer
FOCAS1/Ethernet clients that can be connected
simultaneously than the option board.
2 Communication using the embedded Ethernet function is
processed by the CPU of the CNC. This means that the
CNC operation status may affect embedded Ethernet
communication performance and that embedded Ethernet
communication may affect CNC processing.
The embedded Ethernet function operates with lower
priority than automatic operation processing and
processing performed for each axis such as manual
operation. Therefore, when automatic operation is in
progress or when there are many controlled axes, the
communication speed may lower.
Contrariwise, the embedded Ethernet function operates
with a higher priority than CNC screen display processing,
the C executor (except high–level tasks), and the macro
executor (except execution macros). As a result,
communication using the embedded Ethernet function may
lower the performance of such processing.
3 When the embedded Ethernet function is connected to a
network using a large amount of broadcast data such as an
intranet, processing on broadcast data requires too much
time, which can affect the performance of CNC screen
display processing and so forth.
