Modbus TCP Protocol
You can communicate with the ECO 208 PRO simultaneously via several data connections using the Modbus
TCP protocol.
The ports 502, 503, 504, 505 and 506 are preset for the Modbus TCP data connections.
Up to 10 simultaneous data connections are possible per port. In total, the number of data connections must be
limited to 20. The IP address is preset to DHCP operation.
The Modbus protocol has a standardised structure. The following is a small excerpt of the addressing overview.
The complete Modbus addressing overview can be found in the Programming Manual in the download area of the
ECO 208 PRO and within the Config Tool 3 software.

Your desired protocol not included?
The ECO 208 PRO is extremely powerful due to the Maxi data interface used. On request, we can also integrate
other interface protocols. We would be happy to provide you with a quotation for this. Contact us via the technical
support, [email protected].
Note
Up to 10 connections per port are possible via Modbus TCP, but the total number must be limited to a
maximum of 20 connections.
The IP address is preset to DHCP operation.
