3. PC Link Communication

3.1 Overview

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

device such as a PC, graphic panel, or FA-M3's UT link module. Such a device can

be used in communication to read data from D registers or I relays, both of which are

internal registers of the VJ Series signal conditioners.

Maximum overall cable length of 1200 m

for a maximum of 31 substations

Hereafter, PCs are generally 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 VJ Series signal conditioner

with a communication address of 1 to 99.
