3.3.2 Communication with UT Link Module

Communication with FA-M3 is achieved by simply connecting the M Series to a UT

link module using the PC link communication protocol. Set the communication

conditions of the M Series identical to those of the UT link module.

FA-M3

Model of UT link module: F3LC51-2N

A maximum of 1200 m; up to 31 slave stations

The UT link module supports the following two types of communication modes and com-

mand communication, which allow you to communicate with FA-M3 without being aware of

it. For more information, see the optionally available "UT Link Module User's Manual (IM

34M6H25-01E)."

1. Automatic mode

This mode enables the instrument's fixed devices (those that cannot be specified by

the user) to be constantly refreshed by reading from them. The fixed devices are

D0001 to D0004. They are read-only areas and cannot be written into.

2. Manual mode

This mode enables the instrument's devices (those that can be specified by the user)

to be constantly refreshed by reading from and/or writing into them.
