Hi Steve,
Thanks for reply.
It looks complex for my experience because I have only done one implementation level 3 to level 4 from MES to ERP integration.
The plant i visited have only one terminal which is connected to a pc as mentioned earlier.They are sending the orders through excel file to the scale and again they are importing data to excel file after process completion.
The user wants to send orders from ERP to the scale and updated data from scale to ERP. So can i achieve this by implementing OPC server(OPC server to ERP and vice versa ). Can this be achieved by using pco and sap mii?
It looks like i need to study more on communication protocols to determine OPC server and PCO as i am new to these scales and have no knowledge on these scales.
Thanks for your wonderful help and sharing your knowledge.
Regards,
Goutham
