Using WT30 Terminal as a Relay Station

Extending
Communications Distance
Note
60
The relay function extends the communications distance using an I/O Slave
Station as a Relay Station. Even if equipment is relocated, making communi-
cations between the Serial Master Station and I/O Slave Stations unstable or
resulting in a disconnection, the communications path can be switched,
enabling communications to continue automatically via a Relay Station.
When the Serial Master Station and I/O Slave Stations are separated by a
long communications distance, communications with stations for which radio
waves are difficult to reach can be made possible with the use of a Relay Sta-
tion. I/O Slave Stations are also registered through the Relay Station. Only a
single Relay Station can be used, but up to 64 I/O Slave Stations can be con-
nected to the Relay Station.

The I/O terminals and error output terminal settings on the I/O Slave Station
being used as the Relay Station are disabled. If an I/O Slave Station is within
the communications range for the Serial Master Station, communications with
the Serial Master Station can be performed directly even if a Relay Station is
installed. Relays are supported for only one stage, i.e., only for one Relay Sta-
tion.
