7.C0MPUTER INTERFACING
7.1.
INTRODUCTION
Using the RS232 port on the chamber the Format 550 can be interfaced to PC compatible
computers.
Primarily there are at present two methods available to the user. However, this area of
application continues to develop rapidly. If this manual does not fully address your
application please contact SANYO Gallenkamp PLC or your dealer.
7.1.1 HOST SYSTEM
This is a software package that can be installed onto the hard disk of apersonal computer.
It enables the connection of up to 8 Format 550 controllers. Each can be addressed
individually to allow uploading and downloading of programs.
It can be ordered from SANYO Gallenkamp PLC or your dealer (part number E03554).
In fact this package can network a mixture of Format 500 & Format 550 controllers. The
following notes deal with only a single connection to a single Format 550.
7.1.2 COMPUTER INTERACTIVE
In this situation software is written by the user to enable his chamber to be "slaved" to
some other intelligent device. Typically this might be a system controller that is
managing a test procedure being conducted on the test piece within the chamber. The
system controller can make decisions and direct the operation of test device and/or
chamber.
At a simple level this can take the form of the system controller requiring data about the
chamber condition to add to a log already being acquired. A substantial protocol supports
these interactions, & is described in section 8.2.
