5.3.3 WINDIAG Diagnostic Utility
Caution
The ControlWave ExpressPAC cannot execute your control strategy
while it runs diagnostic routines; place any critical processes
controlled by the ControlWave ExpressPAC 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 ExpressPAC
must be attached to and communicating with a PC running WINDIAG.
Establish communication between the ControlWave ExpressPAC
(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
ExpressPAC to 9600 baud in preparation for diagnostic testing and
prevents the boot project from running and also places the
ControlWave ExpressPAC in diagnostic mode.
 Connect any ControlWave ExpressPAC serial communication port
to the PC provided their port speeds match. Use a null modem cable
to connect RS-232 ports between the ControlWave ExpressPAC and
the PC; use an RS-485 cable to connect the RS-485 port of the
ControlWave ExpressPAC 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.
