Configuring the Bridge

3.9.2Using Dynamic Routing

First setup the bridge for Host--based or Socket--based routing.

The bridge will now associate messages from the host’s IP address with the Modbus Plus path you established, when you address those messages to the Destination Index defined for the Host--based or Socket--based routing.

H Destination Index 0: Host-based routing After you setup the bridge for Host--based routing from a TCP/IP host to a Modbus Plus path, any messages from that host addressed to index 0 will be routed to that path.

The bridge maintains a cache of 10 associations between TCP/IP hosts and Modbus Plus paths using Destination Index 0. Thus up to 10 hosts may set associations and use them concurrently for transactions with Modbus Plus nodes. If all 10 cache locations are in use and another host establishes an association to index 0, the new association will overwrite the oldest one in the cache.

This routing option allows the bridge to be configured for simple addressing from TCP/IP nodes which do not support routing through gateways, such as programming panels.

H Destination Index 254: Socket-based routing After you setup the bridge for Socket--based routing from a TCP/IP host to a Modbus Plus path, any messages from that host addressed to index 254 will be routed to that path.

The TCP/IP host can initiate messages to the Modbus Plus destination for the duration of the host’s connection to the bridge. When the connection terminates, the Modbus Plus path no longer exists for that TCP/IP host.

The bridge maintains up to 16 available socket connections, corresponding to its eight Program and eight Data paths. For example, Modsoft panel software uses both a Program and a Data path during its connection with the bridge. The bridge will establish a socket for both paths during dynamic routing, and will close the sockets when the connection is terminated.

This routing option allows the bridge to handle concurrent sessions from multiple TCP/IP hosts using independent routing assignments. It provides a means for your application to manage routing dynamically in addition to the fixed routings you configure in the bridge’s TCP/IP to Modbus Plus mapping table.
