Troubleshooting
Before You Begin
This chapter describes the utilities that come on the diagnostic/utilities disk
with the open controller CPU module. In addition to the open controller
diagnostic/utilities disk, you can also use standard PC troubleshooting
software packages, such as QAPLUS, on the open controller system.
Using the Diagnostics Utility
The diagnostic/utility disk has a menu system for selecting the utility you
want to run. You can either run the program
ocmenu
to start the menu
system or you can make the disk a bootable disk and use our
autoexec.bat
file that launches the menu system automatically.
Important: The diagnostic utility disk includes a
readme.txt
file that
contains important information. This file also contains
instructions for making the disk bootable.
We recommend that you make the diagnostic/utility disk bootable (use the
DOS
sys
command) so you can run diagnostic utilities from a remote PC
that is connected to the open controller CPU module.
Most of the diagnostic utilities come in two versions:
•
DOS, Windows 3.x, and Windows 95
•
Windows NT
The Windows NT version requires that you load the open controller runtime
API for Windows NT.
If you are using a different operating system, use a bootable DOS disk to
load DOS, and then use the
hostsvr
utility and to run the diagnostic
utilities.
When loading the Windows NT API, select “Yes” when prompted to load
the runtime software.
