2.1.2Routing to Host Based Network Adapters

￿or host based network adapters, the byte following the adapter's network node address specifies a task number (1 ... 8) to which the message is assigned. Subsequent bytes are not checked by the adapter, and are available for custom use to the application - for example, for message counts or status information.

2.1.3Routing to BM85 Bridge/Multiplexers

Routing to Serial Ports on BM85 Programmable Models

￿or the programmable models, the user application stored in the BM85 defines the addressing between Modbus Plus and the serial ports.

Routing to a Single Slave Device on BM85 Modbus Models

￿or a single slave device at a Modbus port, two bytes are used to address the device. The next-to-last non-zero byte addresses the BM85 node (1 ... 64). The last non-zero byte specifies the Modbus port (1 ... 4), and therefore specifies the single slave device.

￿igure 5 shows an example of routing to a single slave device.

Routing to a Networked Slave Device on BM85 Modbus Models

￿or a slave device on a Modbus network at a Modbus port, three bytes are used to address the device. The third byte from the last non-zero byte addresses the BM85 node (1 ... 64). The next-to-last non-zero byte specifies the Modbus port (1 ... 4). The last non-zero byte specifies the Modbus address of the slave device (1 ... 247).

￿igure 6 shows an example of routing to a networked slave device.
