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 the WINDIAG program and then
exit the Netview Program if there aren’t any other ControlWave EFM 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 the ControlWave EFM CPU Switch SW2-8 to the ON (Open) position. The
ControlWave EFM should resume normal operation.
3.5.1 Diagnostics Using WINDIAG
All ControlWave EFM Modules except the System Controller Module 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 Module (except for RAM & PROM).
PROM/RAM Diagnostic: Checks the CPU’s RAM and PROM hardware.
Communications Diagnostic: Checks Comm. Ports 1, 2, 3, 4, 5, 8 and 9 - The External
loop-back tests require the use of a loop-back plug.
Analog Output Diagnostic: Checks AOs on AI/O & Mixed I/O Modules.
Analog Input Diagnostic: Checks AIs on AI/O & Mixed I/O Modules.
Discrete I/O Diagnostic: Checks DIs or DOs on DI/O & Mixed I/O Modules.
High Speed Counter Diagnostic: Checks HSCs on HSC & Mixed I/O Modules.
3.5.1.1 Communications Diagnostic Port Loop-back Test
WINDIAG’s Communications Diagnostic Menu (see Figure 3-11) 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:
Ports 1, 2, 4 & 8 - RS-232 use a 9-pin female D-type loop-back plug (see Fig. 3-9).
Ports 3, 5 & 9 - RS-485 use a 9-pin female D-type loop-back plug (see Fig. 3-10).
This group of tests verifies the correct operation of the Communication Interface. COM1,
COM2, COM3, COM4, COM5, COM8 and COM9 can be tested with this diagnostic. The
ControlWave EFM communication 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 ControlWave EFM 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 EFM communication port that is connected
to the PC (RS-232, RS-485 or Ethernet) must be good for WINDIAG to run the
Communications Diagnostics
3.5.1.2 Serial Comm. Port External Loop-back Test Procedure
Connect an external loop-back plug to the CPU Port to be tested, i.e., J3 of CPU for COM1,
J4 of CPU for COM2 2, J5 of CPU for COM3, J1 of ECOM1 for COM4, J2 of ECOM1 for
COM5, J1 of ECOM2 for COM8 or J2 of ECOM2 for COM9 (see Figures 3-9 through 3-11).
