Hi,

 

We are currently working on the proposal of OPC connections, below is
the situation

IRS PLC

PLC Siemens S7 300 series, TCP/IP

Cut Size PLC

PLC Siemens S7 300 series, TCP/IP

Winder PLC

PLC Siemens S7 300 series, TCP/IP

Roll Handling PLC

PLC Siemens S7 300 series, TCP/IP

Roll Wrapping PLC

PLC Siemens S7 300 series, TCP/IP

Folio Sheeter PLC

PLC Siemens S7 300 series, TCP/IP

Rewinder PLC

PLC Siemens S7 300 series, TCP/IP

Pallet Shrink PLC

2 Siemens S7 400 Series, 1 Siemens S7300 Series, Profibus

Core Cutter PLC

Siemens S7 400 series, TCP/IP


For the PLCs marked in blue, since they support TCP/IP, we need to find
a 3rd party OPC Server for data retrieval, but not very clear on which
OPC Server is preferred.
For the PLC marked in red, TCP/IP is not supported, and using Profibus
as interface, we don't know how to connect for now.

Could anyone give us some advice on this, or existing scenario/solution would be much preferred. Especially for Profibus PLC connection, an reference soluction would be better and highly appreciated.

 

Thank you.
