3. PC Link Communication

3.1 Overview

The use of PC link communication enables the M Series to communicate with a

device such as a PC, graphic panel and FA-M3 UT link module easily. In this commu-

nication, you can use such device to read/write data from/into D registers or I relays,

both of which are internal registers of the M Series.

A maximum of 1200 m; up to 31 slave stations

Figure 3-1 Example of Connection for PC Link Communication

Hereafter, PCs etc. are generically called "higher-level devices."

See Also

Chapters 6 and 7 for information on the D registers and I relays.

In PC link communication, a higher-level device identifies each M Series with an address

number, which ranges from 01 to 99.
