1.4 Configuring the Programmable Models
Developing the Application
When you configure the customĆprogrammable models, you must
develop the entire BM85 application as a file and then download it into
the BM85. This includes the operating code for message handling,
buffer allocation, protocol conversion, and your serial port parameters.
You can create the application program on an IBM PCā/āAT or compatible,
using Modicon software development tools that are shipped separately
from the BM85. These require the use of a Borland Cā/āC++ development
environment which must be supplied by the user.
In addition to its internal configuration, the BM85's Modbus Plus node
address must be assigned. This is done in a set of hardware switches on
the rear panel.
Downloading the Application
The compiled application can then be downloaded to the BM85 using a
utility supplied with the Modicon tools. The download host can be the
same computer that was used for developing the application, or a
separate computer.
For downloading, the host must contain a Modicon SA85 Modbus Plus
network adapter (for an IBM AT-compatible host) or Modicon SM85
adapter (for an IBM Micro Channel-compatible host). If a network
connection is available for the BM85 in the vicinity of the host node, you
can download and debug your application locally. Otherwise, you can
download it to the BM85 at its installation site.
When the user application has been stored in the BM85, it will be
retained by the BM85 after power is removed. If the parameters are
correct for the intended installation site, the unit can be transported to
the site and installed there without reconfiguration.
