Configuring the Bridge

3.9Dynamic Routing of Messages

In addition to the mapped routing of messages from TCP/IP to Modbus Plus, messages can be dynamically routed in this direction at runtime. Dynamic routing is available only to connections initiated fromTCP/IP.

The bridge reserves three Destination Indexes for dynamic routing. A TCP/IP host node uses index 255 to set the bridge for two kinds of dynamic routing from that host. Then the host uses indexes 0 (zero) or 254 to dynamically route messages. Index 0 provides Host--based routing for up to 10 TCP/IP hosts concurrently. Index 254 provides Socket--based routing for the duration of the host connection.

3.9.1Setting Up the Bridge for Dynamic Routing

You must setup the bridge for dynamic routing before you can use it. Note that dynamic routing is implemented at runtime and is not part of the bridge’s internal configuration.

To setup the bridge for dynamic routing, address the bridge using its Destination Index for an internal bridge command (255). Write the Modbus Plus destination node’s five--byte routing path as data into one of these registers:

HRegister 1 for Host--based routing

HRegister 255 for Socket--based routing.

The data portion of the write command must contain three words in the form:

<byte_count><5-byte_Modbus_Plus_path>

Example

The following example sets up a Host--based routing to a Modbus Plus node destination on the routing path 30.18.9.37.2:

Note that the five--byte routing path must be preceded with a byte (always containing 05) to show the length in bytes of the routing path.
