1.10 Network Application
Integra-TR is suited to a variety of network ap-
plications. Its primary design goal was to satisfy
the needs of SCADA systems using RTUs or
PLCs in either point to point or point–multipoint
service.

1.10.1 RF Path and Communications
Range
Integra-TR is designed for use over distances up
to 30 miles (50 km) depending on terrain and
antenna system. To assure reliable commun-
ications, the RF (radio frequency) path between
stations should be studied by a competent pro-
fessional, who will then determine what anten-
nas are required, and whether or not a repeater is
needed.

While an RTU or PLC is shown in the diagram,
master stations often use a PC running an appli-
cation designed to communicate with remote
RTUs or PLCs.

The Setup PC is used for both configuration and
local and remote diagnostics. It may be left con-
nected at all times if desired, but is not required
for normal operation once the unit has been con-
figured.

1.10.3 Common Characteristics
The networks described below share a number
of common characteristics.
of common characteristics.
1. The network speed (4800 or 9600 b/s) must
be the same for all stations in a network.
2. Unless otherwise noted, the default setting
of station type is “master” and data delivery
is “all”.

3. Transmission of online diagnostics may be
enabled or disabled at any station or stations
without affecting their ability to commun-
icate with other stations.
