S7 1500 To Kepware OPC - without having the direct connection to the PLC

My client not going the provide any access to get the S7 1500 PLC data to my kepware OPC. They are telling that, through the IPC127E collect the s7 1500 data with only the read access.

Here my question is, 

Is there of any possibilities available to have the s7 1500 data to kepware OPC without having the direct connectivity with the PLC?

Note: I have suggested to put new s7 1500 PLC to collect the data using the PUT/GET function. but they are not allowing to go with this solution. 

Hello ,

The TCP/IP driver of Siemens possibilities the connection with KEPServerEX for communication between the OPC clients and the S7-1500 by using TCP/IP Ethernet protocol.

Use the link for further informations to Kepware.
