5.4 WINDIAG Diagnostic Utility
Caution
The ControlWave GFC Plus cannot execute your control strategy while
it runs diagnostic routines; place any critical processes controlled by
the ControlWave GFC Plus under manual control before starting this
procedure.
WINDIAG is a software-based diagnostic tool you use to test the
performance of I/O, CPU memory, communication ports, and other
system components. .
WINDIAG is a PC-based program, so the ControlWave GFC Plus must
be attached to and communicating with a PC running WINDIAG.
Establish communication between the ControlWave GFC Plus
(with/without an application loaded) and the PC with a local or network
port under the following conditions:
 Set CPU module switches SW2-3 to OFF and SW2-8 to OFF.
Turning these switches off sets all serial ports on the ControlWave
GFC Plus to 9600 baud in preparation for diagnostic testing and
prevents the boot project from running and also places the
ControlWave GFC Plus in diagnostic mode.
 Connect any ControlWave GFC Plus serial communication port to
the PC provided their port speeds match. Use a null modem cable to
connect RS-232 ports between the ControlWave GFC Plus and the
PC; use an RS-485 cable to connect the RS-485 port of the
ControlWave GFC Plus and the PC. See Chapter 2 for information
on cables.
 Reserve the port running a diagnostic test for exclusive use; you
cannot use that port for any other purpose during testing.
Follow these steps:
1. Start OpenBSI communications using NetView, TechView, or
LocalView, and select the RTU you want to test.
2. Select Start >Programs > OpenBSI Tools >Common Tools >
Diagnostics. The Main Diagnostics menu (Figure 5-5) opens.
