3.5How Mapping Works: TCP/IP to Modbus Plus

Each Modbus Plus message destination is defined by a five--byte Modbus Plus routing path. The use of the path is specific to each type of Modbus Plus device. Refer to the guidebooks supplied with your Modbus Plus devices for details, or refer to the Modbus Plus Network Planning and Installation Guide, part number 890 USE 100 00, for a general description of Modbus Plus routing paths.

Messages received by the bridge from Ethernet host nodes contain an embedded Destination Index byte in the range 1 ... 255 decimal. This byte corresponds to the dest_idx field in messages constructed by Modicon panel software such as Modsoft and Concept.

The bridge uses the Destination Index byte to determine the type of routing to be made.

3.5.1Destination Indexes 1 ... 249: Mapped Routing

The bridge uses Destination Indexes 1 ... 249 to map messages from a TCP/IP node to a Modbus Plus destination node.

The bridge maps Destination Indexes in this range to one of 249 possible Modbus Plus routing paths. Each Destination Index value maps to a location in a Modbus Plus mapping table, which contains a five--byte Modbus Plus routing path to the destination node.

Your configuration of the bridge must include entries into the bridge’s mapping table to correlate the Destination Indexes to your routing paths for Modbus Plus nodes in your application.

Section 3.6 describes how to set up the TCP/IP to Modbus Plus mapping table.
