Mirroring 
Mirroring is used to configure whether the module should duplicate Ethernet packets on a given 
port such that they can be read from a device connected to that port, e.g., for test purposes. 
The following parameters define how a given port should work: 
This port does not participate to the mirroring process. 
Outgoing data of this port are duplicated. 
Incoming and outgoing data of this port are duplicated. 
This port is used to send duplicated data. 
Default setting: OFF 
4.3.2  Network Ports Used for Ethernet Communication 
UDP Ports / Use 
SNTP (time synchronization between PES and remote I/O, PES and external 
devices) 
Modbus salve (can be modified by the user) 
PES used to configure the remote I/Os 
Programming and operation with SILworX 
PROFINET endpoint mapper (required for establishing the connection) 
 
TCP Ports / Use 
Modbus salve (can be modified by the user) 
TCP SR assigned by the user 
 
All ports listed above are destination ports. The source ports of the communication modules are 
variable and cannot be affected. 
The ComUserTask can use any port if it is not already used by another protocol.
