SIDIR Ports setting

Question

The SIDIR driver defaults to using 102 Port for data communication with Siemens PLC. Can the default communication port for this setting be modified at the driver layer? 
 Note: Some sites may use NAT gateways for IP and port translation due to PLC IP conflicts, so it may be necessary to use multiple different ports of the same IP to map multiple PLC addresses for communication.

Hi, Port 102 (S7 Protocol) cant be changed in Siemens PLC's. So regardless of whether it can be changed in the driver (Aveva SIDIR), you won't get any further when the PLC only listens on port 102.
