3-12 / Service CI-ControlWave Express
4. Select the module to be tested. Enter any prompted parameters (slot #, etc.). WINDIAG
will perform the diagnostics and display pass/fail results.
5. After all diagnostic testing has been performed, exit WINDIAG program and then exit
the NetView.
When you close Netview, you will be prompted as to whether or not you want to close
OpenBSI; select Yes.
6. Set ControlWave Express CPU/System Controller Board Switch SW2-8 to the ON
(Open) position. The ControlWave Express should resume normal operation.
3.5.1 Diagnostics Using WINDIAG
ControlWave Express electronics can be tested using the WINDIAG program. From
WINDIAG’s Main Diagnostics Menu (see Figure 3-8) the following diagnostic tests can be
performed:
CPU & Peripherals Diagnostic: Checks the CPU/System Controller Board [except for
RAM & PROM (FLASH)].
PROM/RAM Diagnostic: Checks the CPU/System Controller 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 a loop-back plug.
Analog Output Diagnostic: Checks AOs on the Process I/O Board.
Analog Input Diagnostic: Checks AIs on the Process I/O Board.
Discrete I/O Diagnostic: Checks DIs or DOs on the Process I/O Board.
High Speed Counter Diagnostic: Checks HSCs on the Process I/O Board & Pulse Counter
Inputs on the CPU/System Controller Board.
Keyboard & Display Diagnostics Checks Keyboard/Keypad & Display hardware
3.5.1.1 Communications Diagnostic Port Loop-back Test
WINDIAG’s Communications Diagnostic Menu (see Figure 3-10) 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, a special loop-back plug is required as follows:
Port 1 - RS-232 use a 9-pin female D-type loop-back plug (see Fig. 3-8).
Port 2 - RS-232 use loop-back wires (see Figure 3-8).
Port 3 - RS-232 use loop-back wires (see Figure 3-9)
Port 3 - RS-485 use loop-back wires or CPU Switch SW3 (see Figure 3-9).
This group of tests verifies the correct operation of the Communication Interface. COM1,
COM2 and COM3 can be tested with this diagnostic. The ControlWave Express
communication port that is connected to the PC (local or network and used for running
these tests) cannot be tested until diagnostics has been established via one of the other
ports, i.e., to test all ControlWave Express 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 Express communication port that is
connected to the PC (RS-232, RS-485 or Ethernet) must be good for WINDIAG to run the
Communications Diagnostics
