7.1 WAHT IS THE I/O LINK
The FANUC I/O Link is a serial interface, which passes input/output
signals between the PMC and each I/O device at a high speed.
For each channel, up to 1024 DI points and up to 1024 DO points can be
connected and controlled from the PMC.
The update cycle of the signals from I/O Link depends on the
combination with each PMC and each I/O Link channel. The update
cycle of the signals from I/O Link when each PMC uses each I/O Link
channel is shown in the following table.
