The four serial ports on these models are programmable by the user to support custom RS232 or RS485 serial devices.

These models must be downloaded with an executable BM85 application program across the Modbus Plus network. The downloaded image contains all of the internal operating code used by the BM85, including communication protocols for the serial ports: handshaking, protocol translation between ports, message packaging, buffer space, data conversion, and error handling. Each serial port indicator is individually programmable to show the port's status in the application.

The image can contain all of the serial port parameters (for example, baud rates and parity) as fixed parameters. Alternatively the image could provide a local protocol (default parameters and a menuing system) for the user to locally configure the serial ports through a terminal at one of the ports.

In addition to standard serial devices, Modbus master or slave devices could be attached at RS232 serial ports if the user4defined code includes a Modbus protocol handler.

You can create the BM85 application program on an IBM PC3/3AT or 100% compatible, using Modicon BM85 software development tools. These are available from Modicon Customer Service and are shipped separately from the BM85. Details of the development tools are provided in Section 1.4.1.

The BM85 can operate as a fully4programmed processor in the user application. The unit can locally manage processes at its serial ports,
