5-1.7 Initial Tests
Initial tests of the system involve the use of the Focus soware to perform a thorough check of the
system. The basic approach to performing these tests is to use the soware to apply simulated inputs
to the controller and to check the eect on the output circuits. The following paragraphs describe the
Focus soware and the checks to be performed as part of initial tests.
5-1.7.1 Omni Web Server
Tests of the system are simplified by use of the on-board web server. The web server allows the
operator to trace the flow of control and to view the various values within a configuration residing in
a controller. Each controller can be monitored one at a time in real time. Therefore, what appears on
the screen is what is actually happening inside the controller.
5-1.7.2 Performing Initial Tests
Because of the Omni system’s flexibility, the various configurations can be vastly dierent from each
other. For this reason, it is not practical to provide detailed procedural instructions for performing
initial tests that apply to all configurations. However, this paragraph describes the general
methodology for performing the initial tests.
Initial tests using the on-board web server are divided into three separate phases; these tests should
be performed on each controller in turn:
•In the first phase of testing, power is removed from all output circuits and the web server is used to
monitor the states and input/output values of the various configuration blocks using variable input
stimuli. This phase serves two purposes: It checks the configuration of the controller and it helps
to familiarise the operator with the operation of the system.
•In the second phase of testing, the controller’s primary output circuits, such as motor controllers
and relay circuits are energised but the output machinery (fans, pumps, compressors, etc.) are
de-energised. In this phase, the controller inputs are stimulated just enough to cause the output
circuits to operate or change state. This phase checks the operation of the output control circuits
without operating the plant machinery.
•In the third phase, the primary output control circuits as well as the plant machinery are
energised. In this phase the controller inputs are carefully stimulated just enough to briefly test
the operation of the plant machinery. This phase should involve the minimum of controller input
stimulation required to operate the machinery.
