| Subject: | Using SteepleChase on a EPSON RC+ system |
Purpose
This document contains instructions on using SteepleChase
on a EPSON RC+ system.
Initial testing has been completed at Epson America,
Inc. and it has been found that SteepleChase will run on a EPSON RC+ PC along
with EPSON RC+.
There are a few items that you need to be aware of as
described below.
System Startup
The SteepleChase VLC system uses the
INtime real time operating system. This system must be started first,
before starting EPSON RC+.
If EPSON RC+ is started before VLC, then when
VLC is started, an interrupt overtime message will be displayed and you will
have to restart the SPEL runtime drivers.
Once VLC has been started for the
first time, you can close and reopen both VLC and EPSON RC+.
VLC Scan
Rates
You
may need to increase scan time to allow more CPU time for Windows NT processes
(including EPSON RC+). This depends on how much time each system needs to
complete processing.
Live Video
You can display live video
while VLC is running with no problem. However, to minimize CPU usage
during runtime, it is recommended that vision sequences have their
RuntimeFreeze properties set to True (which is default) so that video is not
constantly live. Again, this depends on how much time each system needs
to complete processing.
Communication between EPSON RC+ and
VLC
VLC supports OPC, DLL,
and DDE communcations. You can use Visual Basic or Visual C++ to
communicate with VLC and with EPSON RC+ using the SPELCom ActiveX
controls. SPEL+ can also make DLL calls.
