Configuring the Bridge

3.8Setting the Mapping: Modbus Plus to TCP/IP

Each message from a Modbus Plus node contains a five--byte routing path field (See Section 3.7). The bridge uses the third byte to index into its TCP Mapping table, extracting an IP address from that entry.

You can edit the table to map the Modbus Plus routing path’s third byte to specific IP addresses in your application.

3.8.1TCP Mapping Table Layout and Default Entries

The TCP Mapping table contains 255 fields, labeled TCP_1 through TCP_255. These fields define IP addresses for messages (from Modbus Plus nodes) which contain 1 through 255 decimal in byte 3 of the Modbus Plus message routing path.

By default the bridge automatically sets the first three bytes of each IP address to match the first three bytes of the bridge’s IP address. (See Figure 14 and Section

3.4.3for an example of configuring the bridge’s IP address.) The bridge sets the fourth byte of the IP address mapping to the range 1 ... 255.

For example, if you configure the bridge’s IP address as:

205.167.7.65

the TCP Mapping table’s 255 locations will automatically default to:

TCP_1:

205.167.7.1

TCP_2:

205.167.7.2

. . .

. . .

TCP_255:

205.167.7.255

Figure 18 shows an example of typical default TCP mapping, with one custom routing entry made by the user.
