5.2.4. Calculating the ICC ETH-1000 DB Addresses

One of the most important steps in configuring a service object is to determine the Database Address that needs to be entered. Since the ICC ETH-1000 DB is a “shared database” between EtherNet/IP and MELSEC protocols, one has to define carefully which way the data items will be written to and read from.

Figure 3 of this document in Section 5.1 shows the mapping of data from ControlLogix to the ICC DB. This mapping is then expanded to map from ICC DB to the Mitsubishi controllers connected to the ICC gateway in the system.

The following diagram illustrates an example of the mapping the ICC DB to Mitsubishi iQ system with an Built-in Ethernet port and an external Ethernet module. Each Ethernet port transfers 10 words of bit data and 20 words of word data.

The DB addresses configured in the MELSEL service objects are the beginning addresses of each block of data shown above. The ICC DB addresses are “Byte” addresses so that starting address locations need to be adjusted accordingly.

A Microsoft Excel-based database address calculation tool is available from Mitsubishi Electric Automation, Inc. upon request. The tool can be used to calculate the DB locations of MELSEC service objects to assist the configuration efforts. Please contact your MEAU representatives to obtain a copy of this tool.
