Image RemovedImage Added

Server settings

  • line: TCP/IP-TCP(Host ALL, port 2404)
  • protocol: IEC 870-5-104 Server
  • parameters: none

Client settings

  • line: TCP (Host IPA1,IPA2, port 2404)
  • protocol: IEC 870-5-104
  • parameters: none

...

Example 2: Client communicating with the redundant servers SrvA, SrvB.

Image RemovedImage Added

Servers' settings

  • line: TCP/IP-TCP (Host myName or ALL, port 2404)
  • protocol: IEC 870-5-104 Server
  • parameters: SKO=TRUE; SWV=False; SSCF3=True;

Client settings

  • line: TCP/IP-TCP Redundant (Primary host IPA, Secondary host IPB, both ports 2404)
  • protocol: IEC 870-5-104
  • parameters: SKO=True;ICF3=True;

...

The client communicates both with the hot server and with the standby server, connection with the standby server continues to be open, but new values are send by the hot server.
Note: If symbolic myName is used, it should be defined in hosts file of 1-st server as IPA and in hosts file of 2-nd server as IPB.

Servers' settings

  • line: TCP/IP-TCP(Host ALL, port 2404)
  • protocol: IEC 870-5-104 Server
  • parameters: SKO=True; SWV=False;SSCF3=True;

Client settings

  • line: TCP/IP-TCP Redundant (Primary host IPA1,IPA2, Secondary host IPB1,IPB2, both ports 2404)
  • protocol: IEC 870-5-104
  • parameters: ICF3=True

...

The client communicates with both the servers. If one network segment drops out (e.g. IPA1 failure), the client establishes connection with the server SrvA using the address IPA2.


Example 4: The redundant clients ClientC, ClientD communicating with the redundant servers SrvA,

...
