3.2.7 Communication with FA-M3
Host computers that can use PC link communication protocol can communicate with
FA-M3.

Communication with FA-M3 (UT link module)
The UTAdvanced can communicate with FA-M3 simply by connecting to the UT link
module by PC link communication protocol.
Set the communication conditions on the UTAdvanced to the same conditions as those
on the UT link module.
Communication with UT Link Module
FA-M3
UT link module model name: F3LC51-2N
Up to 31 connected slaves with a maximum length of 1200 m
The UT link module supports two types of communication modes and command
communication. So, data transactions are possible without being aware of
communication. For details, see the "UT Link Module User’s Manual (IM 34M06H25-
01E)."
1. AUTO (automatic) mode
In this mode, fixed devices on the controller (not user-specifiable) are read and
refreshed.
Fixed devices are D registers D2001 to D2025. Fixed devices cannot be written as
they are the read area on the UTAdvanced.
2. MAN (manual) mode
In this mode, the devices (user-specifiable) on the UTAdvanced are read/written and
refreshed manually.
► "Devices" here refers to D registers and I relays.
