Name of the connection
All connections are defined over their names. Most letters are allowed but [ ] and the dot. The names will be used as part of the item name in OPC access. Possibly some OPC clients do not accept all names. Details will show the manual of the client and the user operating system running it.
Network Transport protocol
The transport protocol is selected here, via which Ethernet network the communication is working.
Transport protocol
|

TCP/IP
|
This is mostly used.
The Transmission Control Protocol / Internet Protocol is routable and is now used for communication with PLCs and field devices. TCP/IP should be selected for RFC 1006 (OSI on TCP) communication.
|
OSI-H1
|
OSI OSI-H1-Protocol for connections to Siemens S5 oder S7. Older types may require this protocol.
|
Serial
|
On some devices, mostly Linux, the Serial communication is available.
