Hi Goutham,
According to the documentation available from Mettler Toldedo, the option to implement Ethernet/IP also includes the option to implement Modbus TCP. You can use Modbus TCP with an OPC Server that provides a Modbus TCP driver (Kepware or MatrikonOPC both have this). SAP Plant Connectivity (PCo), and SAP MII are the SAP components needed to integrate the scale and the OPC Server to SAP MES or ERP systems.
Another option would be to implement the communications via the scale Serial Port if present. This would require an external Hardware Serial-Ethernet server to put the serial port on the plant network, and then PCo and MII for the SAP integration components. there is an internal Ethernet port on the IND780 main board, but I did not investigate whether you can communicate with the scale using the same protocols as the serial port, If this is possible, then the Hardware Serial-Ethernet server is not required.
Either solution will require detailed knowledge of the communication protocols to determine the OPC Server, PCo and MII configuration, and MII transaction requirements, to implement the interface.
I would recommend against trying to directly attach to the SQL CE database on the scale.
