Offline Diagnostics - Information is sent by a specific unit in response to an inquiry made locally or from another station.
2.7 FIRMWARE UPDATES
The Integra-TR firmware resides in flash EPROM and is designed to allow field updates.
Updates are done using a PC connected to the Integra-TR but do not require opening the unit. Updates will be coordinated
by DRL’s Technical Service.
2.8 NETWORK APPLICATION
Integra-TR is suited to a variety of network applications. Its primary design goal was to satisfy the needs of SCADA systems
using RTUs or PLCs in either point-to-point or point-to-multipoint service.
This section gives an overview of some common configurations. Selection of “master” or “remote” as well as data delivery
conditions is done using the Integra-TR Field Programming Software.
2.8.1 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 communications, the RF (radio frequency) path between stations should be studied by a competent professional
who can determine what antennas are required and whether or not a repeater is needed. Your CalAmp Sales
Representative can assist you.
2.8.2 BASIC CONNECTIONS
The connections required are shown in Figure 3.
While an RTU or PLC is shown in the diagram, master stations often use a PC running an application 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 connected at all times but is not required for normal operation once the unit has been configured.
