1.4 Configuring the Programmable Models

Developing the Application

When you configure the custom/programmable 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 PC./.AT or compatible, using Modicon software development tools that are shipped separately from the BM85. These require the use of a Borland C./.C++ 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.
