5. After all diagnostic testing has been performed, exit the WINDIAG program and then
exit the Netview Program if there aren’t any other ControlWave XFC units to be
tested. When you close the Netview program you will be prompted as to whether or not
you want to close the OpenBSI program; select Yes
6. Set ControlWave XFC CPU Switch SW1-8 to the ON (Open) position and then cycle
the power (OFF then ON). The ControlWave XFC should resume normal operation.
3.5.1 Diagnostics Using WINDIAG
ControlWave XFC electronics can be tested using the WINDIAG program. From WIN-
DIAG’s Main Diagnostics Menu (see Figure 3-4) the following diagnostic tests can be per-
formed:
CPU & Peripherals Diagnostic:
Checks the CPU Board [except for RAM & PROM
(FLASH)].
PROM/RAM Diagnostic: Checks the CPU Board’s RAM and PROM (FLASH)
hardware.
Communications Diagnostic: Checks Comm. Ports 1, 2 and 3 - The External loop-back
tests require the use of loop-back wires.
Analog Output Diagnostic: Checks AOs on the System Controller & I/O Board.
Analog Input Diagnostic: Checks AIs on the System Controller & I/O Board.
Discrete I/O Diagnostic: Checks DIs or DOs on the the System Controller & I/O
Board.
High Speed Counter Diagnostic: Checks HSCs on the the System Controller & I/O Bd.
Display Diagnostics Checks Display hardware
3.5.1.1 Communications Diagnostic Port Loop-back Test
WINDIAG’s Communications Diagnostic Menu (see Figure 3-7) provides for selection of the
communication port to be tested. Depending on the type of network (RS-232 or RS-485) and
the port in question, different loop-back wires are required as follows:
Port 1 - RS-232 uses a single loop-back wire (see Figure 3-5).
Port 2 - RS-232 uses three loop-back wires (see Figure 3-5).
Port 3 - RS-485 doesn’t require loop-back wiring.
This group of tests verifies the correct operation of the Communication Interface. COM1,
COM2 and COM3 can be tested with this diagnostic. The ControlWave XFC com-munication
port that is connected to the PC (local or network and used for running these tests) can’t be
tested until diagnostics has been established via one of the other ports, i.e., to test all Con-
trolWave XFC communication ports (via WINDIAG), communications with the PC will
have to be established twice (each time via a different port). It should be noted that the
ControlWave XFC communication port that is connected to the PC (RS-232 or RS-485)
must be good for WINDIAG to run the Communications Diagnostics
3.5.1.2 Serial Comm. Port External Loop-back Test Procedure
Connect external loop-back wire(s) (on the Terminal Plate) to the Communications Port to
be tested (see Figures 3-5). Note: The RS-485 port doesn’t require loopback wires.
1. Type "1," "2," or "3" for the port to test.
2. Set baud rate to test to 115200 baud or ALL ASYNC and the number of passes to 5.
