To establish communication with a device, the associated Board, Port and I/O Device need to be correctly configured in Plant SCADA Studio's Topology activity.
If you use the Express Communications Wizard to connect to a device, these settings will be automatically configured for you. However, if you need to configure the settings manually, use the values outlined below.
Board settings
The Boards view lists boards used in the Plant SCADA project. Each board record defines a separate board within the project.
The IEC870IP driver is a board-level driver, which means it requires a single board configured for each I/O server.

Port settings
The Ports view lists the ports used in the Plant SCADA project. Each port record defines a separate port within the project.
A separate port should be created for each IEC 870-5-104 device.
|
Field |
Value |
|---|---|
|
Port Name |
Any user-defined name (e.g. "Port1") |
|
Port Number |
The default port number for the IEC 870-5-104 protocol is 2404. |
|
Board Name |
Refers to the board defined in the Boards form |

|
Stop Bits |
Leave this field blank |
|
Parity |
Leave this field blank |
|
Special Options |
Use the address for the IEC 870-5-104 device using the following format: —I<device IP address> —P<port number> —<T (TCP)> For example: The default port number for the IEC 870-5-104 protocol is 2404 |

I/O Device settings
The I/O Devices view lists I/O devices used in the Plant SCADA project. Each device record defines a device within the project.
A Plant SCADA I/O device represents a single IEC 870-5-104 device.
|
Field |
Value |
|---|---|
|
Name |
Any user-defined name (e.g. "IODevice1") |
|
Number |
I/O device number needs to be unique for each I/O device, |
|
Address |
The address to use for an IEC 870-5-104 device is the common ADSU address. This value is configured on the device and will be a number between 1 and 65535. |
|
Protocol |
IEC870IP |
|
Port Name |
Refers to the port defined in the Ports form |
