Item 6.11.1 Overview
Modified as follows
Before) NOTE
This system enable I/O data transfer between two independent FANUC I/O
Link master device. When the system is adjusted and maintained, the FANUC
I/O Link can be operated with the system power for one of the FANUC I/O Link
lines switched off, that is, the link operation is stopped. In this case, DI data
sent from a system at rest consists entirely of zeros. If one of the links is
stopped, either abnormally or normally, it takes up to several hundred
milliseconds for this function to take effect. During this period, that data which
exists immediately before the link stops is sent out. Take this into account
when designing your system.
After)
This system is enable to I/O data transfer between two independent FANUC
I/O Link master devices. When the system is adjusted and maintained, the
FANUC I/O Link can be operated with the system power for one of the FANUC
I/O Link lines switched off, that is, the link operation is stopped.
NOTE
Take the following point into consideration when you design your system.
1. If one of the links is stopped, the system power supply is turned off for
maintenance or adjustment, or the link is stopped due to a failure of CNC or
I/O Link slave module, the circuit of this unit is designed so that all DI
signals sent from a system at rest consists entirely of zeros.
2. If one of the links is stopped, either abnormally or normally, it takes up to
several hundred milliseconds for NOTE 1 function to take effect. During this
period, that data which exists immediately before the link stops is sent out.
Take this into account when designing your system.
3. It cannot be guaranteed that the operation described to NOTE 1 and
NOTE2 is carried out that way. Therefore, manage signals related to safety
by making a safety circuit outside this FANUC I/O Link connection unit.
Item 6.12.2 Specifications
Deleted the following description
1 All the DOs in the unit are designed to be turned OFF if the Power Mate i
generates a system alarm or if a communication alarm is generated during
communication between the Power Mate i and the unit. Consider this fully
when creating a machine sequence to ensure that the sequence is fail safe.
The DOs are also turned OFF when the Power Mate i or the unit is turned
OFF.
