2 Network System Diagram

The diagrams shown below are the examples of CIMON-SCADA network system configuration.

(1) CIMON Net (Ethernet)

In the diagram shown below, the Client (CIMON) considers the Server #1 and Server #2 as the subordinate I/O Devices. The Server #1 and Server #2 are configured as CIMON-Enet Server (FEP), which transmit the data from subordinate I/O Devices to the Client

(2) CIMON FEP, Server Redundancy, and Client

In the diagram shown below, the network system is configured with FEP, Servers and the Clients. The system is configured with FEP, Server and Line Redundancy.

(3) CIMON Net (RS232/MODEM)

In the diagram shown below, one of the CIMON-SCADA can operate as either a Server or a Client. When the CIMON-SCADA operates as both Server and Client, the Peer-To-Peer connection is also possible.

3. Settings

Select [Tools] – [Network] or icon to bring up the [Network Configuration] window.

3.1 Node Setup

‘Node Setup’ is a section where the user can configure the nodes to be connected to the CIMON-SCADA.

You can add, edit and delete the Server/Client nodes.

New Node	You can add a Server or Client nodes to be connected to the CIMON SCADA.
	Node Name	Enter the name of the node.
	Primary IP Addr.	Assign the primary IP address of the node.
	Secondary IP Addr.	Assign the secondary IP address of the node. This field is activated only when the ‘Line Redundancy’ option is selected.
Edit		Edits the selected node. When you press the button, [Node Setup] window will appear.
Delete		Deletes the selected node.
OK		Applies the network configuration to the project and returns to the graphic page.
Cancel		Cancels the network configuration and returns to the graphic page.

3.2 Features of Node

In the [Features of Node] tab, you can determine the role of the CIMON-SCADA in the network system. You can assign one of the provided functions to the CIMON-SCADA; Client, Primary Server, Secondary Server and Stand-Alone

Function	Stand-Alone	Assigns the CIMON-SCADA as a sole Server. When you select this option, all functions and data for the system operation can be managed in the CIMON-SCADA. You can use CIMON Net to provide tag data to the superior system. (FEP)
	Client	Assigns the CIMON-SCADA as a Client. When you select this option, the CIMON-SCADA will be operated only when the active server is executed. CIMON-SCADA will perform functions using the database provided by the Server. The Client can be connected to the superior system through CIMON-Net.
	Primary Server	This node type includes all of the functions of Stand-Alone and also provides a real-time database to the other system (CIMON-SCADA Client). When you select this option, ‘Server Redundancy’ option is activated. When the ‘Server Redundancy’ option is selected, CIMON-SCADA operates as the Active node.
	Secondary Server	This node type only available in case of the ‘Server Redundancy’. The Secondary Server has an identical specification as the Primary Server and used as a substitute of the Primary Server. The Secondary Server is usually operated as Standby node. However, if the Secondary server is executed before the Primary Server, it can be operated as an Active node. When this node type is selected, ‘Server Redundancy’ option is activated and selected forcibly. You cannot deselect the ‘Server Redundancy’ option
Server Redundancy	Select this option when the server is redundant; Primary Server and Secondary Server. When the Secondary Server is selected, this option is activated and selected forcibly.
Line Redundancy	Select this option when there are more than two IP addresses (two Ethernet cards) in the PC, and use one of the IP addresses as a backup. If this option is selected, the ‘Secondary IP address’ in the [Local Setup] tab must be filled in. In case of the Stand-Alone node, you cannot use this option unless the CIMON-SCADA operates as FEP or View/Control Server.
FEP (CIMON-Net Server)	Select this option to transmit the tag data to the other SCADA through CIMON-Net. You can use Ethernet or RS-232C (Modem) as a communication method. If this option is selected, you must configure the [FEP] tab. FEP communication uses port number ‘UDP 1609 + Value assigned to the Port’.
View/Control Server	Select this option to access CIMON-SCADA through CIMON-View. View/Control Server uses the port number ‘UDP 51000 + Value assigned to the Port’. This option cannot be used with ‘Web Server’ option.
Web Server	Select this option to access CIMON-SCADA through CIMON-Web Client. Web Server uses Http port number 80, UDP 7000 as a default. The port number can be changed. This option cannot be used with ‘View/Control Server’.

3.3 Local Setup

In this tab, you can configure the parameters of the communication between the CIMON-SCADA and the Client (or Server). If the CIMON-SCADA is configured as a Stand-Alone, this tab is disabled.

Primary IP Address	Enter the Primary IP Address of the CIMON-SCADA installed PC.
Secondary IP Address	Enter the Secondary IP Address of the CIMON-SCADA installed PC. This option is enabled only when the ‘Line Redundancy’ option is selected. If the ‘Line Redundancy’ option is selected, the Secondary IP Address must be filled in

Use Dynamic IP	Select this option to use domain name through DNS. When you select this option and press button, you can assign MAC Address to the ‘Primary IP Address’ or ‘Secondary IP Address’.
Port No.	You can assign a port number for TCP/IP communication between the Server and the Client, in range of 0 to 99. Unless the occurrence of the communication error, you are not required to change the default port number. The port number must be same in the Server and Client.
Time-Out	When the communication is not connected in the assigned time, this feature considers that the connection is disabled. If the disconnection time exceeds the value assigned to the Time Out, the Client considers that the Server has an error. In case of the Server redundancy, the Client will try to connect to the Standby server. You can only assign from 1 to 59 seconds

(1) Communication Port

According to the node function selected in the [Features Of Node] tab, the Server uses different Port Number.

If the selected node is an FEP Server, you will assign the port number from 0 to 99 in the [Local Setup] tab. However, the actual port number is from UDP 1609 to 1708.

If the selected node is a Control/View Server, you will assign the port number from 0 to 99 in the [Local Setup] tab. However, the actual port number is from UDP 15000 to 15099.

In case of the Web Server, Http communication port uses TCP 80, and the communication port number for CIMON-SCADA is UDP 7000.

Port No. in [Local Setup] tab	FEP Server	Control/View Server
0	1609	15000
1	1610	15001
2	1611	15002
…	…	…
99	1708	15099

3.4 FEP

In the [FEP] tab, you can select the network type and the parameters for the communication with the superior device. This tab is enabled only when the ‘FEP (CIMON-Net Server)’ option in the [Features Of Node] tab is selected.
