The properties of a port depend on the type of board installed in the I/O server, and on the I/O device connected to the port.
To add a port:
-
In the Topology activity, select Components & Mapping.
-
On the menu below the Command Bar, select Ports.
-
Add a row to the Grid Editor.
-
Type the required information in each column, or in the Property Grid (see below for a description of the properties).
-
Click Save.
Port Properties
General Properties
|
Property |
Description |
|---|---|
|
Server Name |
The name of the I/O server that hosts the board on which the port is located. |
|
Port Name |
A name for the port connected to your I/O Device(s). 31 characters maximum. Each port needs to have a unique name (i.e. you cannot assign the same Port Name to two ports in your system). You can use any name, for example, "Board1_Port1". If you have more than one board in your computer, you can use the port name to identify the board, for example, "Board2_Port1". |
|
Port Number |
The port number that the I/O device is connected to. 4 characters maximum. Avoid assigning the same Port Number to two ports on a board, unless connecting to a dial-up remote I/O device via a modem (see the note below). Ports on different boards can be assigned the same number. If you are using your computer's COM port enter the port number here - the port number is defined in the Ports section of the Windows Control Panel. Note: If you are connecting to a dial-up remote I/O Device (via a modem), you need to define a unique port name on the I/O server for each dial-up remote I/O device, and the port number needs to be -1 for each. |
|
Board Name |
The name you used for the board. 16 characters maximum. This is necessary to link the port to the board. For example "Server1_Board1". |
|
Baud Rate |
The baud rate of the communication channel (between the Plant SCADA I/O Server and the I/O Device). 16 characters maximum. Note: The I/O device hardware and serial board may support other baud rates. If you do choose an alternative baud rate, verify that both the I/O Device and serial board support the new baud rate. |
|
Data Bits |
The number of data bits used in data transmission. You need to set your I/O Device to the same value or a communication link cannot be established. |
|
Stop Bits |
The number of stop bits used to signify the completion of the communication. You need to set your I/O Device to the same value. |
|
Parity |
The data parity used in data transmission. |
|
Special Opt |
Any special options supported by the port. 32 characters maximum. Please check the Hardware Setup Help Topic for your specific I/O Device to see if specific options are necessary. |
|
Comment |
Any useful comment. 48 characters maximum. |
