Stream SCADA can be deployed in many ways. And it supports various Client/Server architectures. This section address the needed settings for the different possible scenarios.


From Stream Explorer, select Network.



Below are several scenarios:


Scenario (1)

  • Scenario description: Single machine running both as server and operator work station.
  • Required Settings:

       Mode: Single

       Address: localhost

       Port: 49110 (Only change it when this port is used by another application).

       Windows User: Everyone


Scenario (2)

  • Scenario description: Two machines; one is the server and the other is the client.
  • Required Settings:

       Mode: Single

       Address: Server IP address (Example: 192.168.1.1)

       Port: 49110 (Only change it when this port is used by another application).

       Windows User: Everyone


Scenario (3)

  • Scenario description: Two redundant servers on two redundant machines.
  • Required Settings:

       Mode: Redundant

       Server address: Server IP address of the local machine (Example: 192.168.1.1)

       Port: 49110 (Only change it when this port is used by another application).

       Windows User: Everyone

  • Required Settings (2nd Redundant Server):

       Server address: Server IP address of the other redundant machine (Example: 192.168.1.1)

       Port: 49110 (Only change it when this port is used by another application).

               

       Check interval (ms): time interval between each check. Both servers will check on each other using this time        interval

       Checking timeout (ms): time interval that each server will wait on the server to respond before declaring its        status as Unknown.

       

       Mode Status Tag: Select a TagName (usually Memory data source) to get the current status of the server as        the following:

       Value -1: Means that the server status is Unknown.

       Value 1: Means that the server status is Active (Executing commands to field).

       Value 2: Means that the server status is Standby (Reading field data without executing commands).


  • DMZ Mode: Using this mode, this server can't write data to Stream SCADA server. Use this mode when it's required to avail data securely without the ability to change data. For example, remote clients and 3rd party systems.
