The second step in the setup process is to add an RTU.
Specify the fields as follows:
| Field | Description |
| RTU Name | This is the name used to identify this RTU. |
| Configuration | Select the configuration that this RTU should use. New configurations are added on the server. |
| Comms Protocol | Specify the communications protocol required to talk to the RTU. The following protocols are supported: Serial / TCP / Modem / Acquire. The selected protocol will determine the setup fields displayed |
| IP Address (TCP Only) | This is the IP address of the RTU. |
| TCP Port (TCP Only) | This is the TCP port of the RTU. For Modbus TCP this is normally 502. |
| Telephone No (Modem Only) | This is the telephone number to dial to contact the RTU. |
| Baud Rate (Serial / Modem) | This is the baud rate of the serial port used to connect to the RTU. |
| Data Bits (Serial / Modem) | This is the number of data bits of the serial port connection. It is normally set to 8. |
| Stop Bits (Serial / Modem) | This is the number of stop bits of the serial port connection. It is normally set to 1. |
| Parity (Serial / Modem) | This is the parity setting of the serial port connection. It is normally set to NONE. |
| Slave Address | This is the Modbus slave address that the RTU will respond on. It is normally set to 1. If you are using multi drop RS422 then each RTU will have its own unique Modbus slave address. |
| RTU Timeout | This is the length of time in seconds that Profile will wait for a response from the RTU. To use the default settings enter 0 in to this field. |
| RTU Connection Timeout | This is the length of time in seconds that Profile will wait for a connection to be made. To use the default settings enter 0 into this field. |
| RTU Stream | This bit will change on the final release. |
| Collect Alarms Every | This popup menu allows you to override the default rate that alarms are requested for the RTU. The default poll rate is 2 seconds although this default poll rate can be modified in the Profile preferences screen. |
| Collect Chart Data Every | This popup menu allows you to override the default rate that historical data is gathered for the chart etc. The default poll rate is 1 minute although this default poll rate can be modified in the Profile preferences screen. |
When you have specified the parameters as required:
| • | Click the 'Save' button to create the new RTU or the 'Cancel' button to cancel the creation of the new RTU. |
Once saved, the RTU screen is then displayed. From this screen you can click 'Add' to add extra RTUs to the site or click on the 'Profile' menu in the Module bar to choose 'Overview' to view real time information from the RTU.
