3.10 FA Link Configuration
To establish data links using the FA Link, it is necessary to set up the FA Link
configuration (hereinafter referred to as link information configuration). The
setting of “link information” here means the assignment of link devices for
each system to each station.
The Link Information configuration is carried out on the FA Link Station
Assignment and Monitoring window of the WideField3.
This setup is stored in the non-volatile memory of each FA Link module and
therefore, once set, does not need to be set again unless a FA Link module is
replaced.
The conditions for the setup values depend on the operation mode of the FA
Link module as shown in the table below.
Note
- FA Link Configuration (Hereinafter referred to as “Link Information
configuration”)
This refers to the information regarding the allocation of the link relays and link
registers to the various stations on a network on the FA Link.
CAUTION
Each FA Link module stores only the link device allocation data of its own (local)
station, but not the data of the other remote stations. Always perform the FA Link
configuration again when a FA Link module is replaced or added.

We describe below how to setup the link Information configuration using the
WideField3. For more details on the WideField3, read the FA-M3 Programming Tool
