Communication station configuration
...
- Communication protocol: Remia E3.
- Station address is set according to the address on a device (0 to 15).
...
Configuration dialog box of station - the tab "Protocol parameters".
Table 1
| Key word | Full name | Meaning | Unit | Default value |
|---|
| Retry Count | Number of retry calls when an error in communication occurs. | - | 2 |
| Retry Timeout | Delay between the retry calls if an error in communication occurs. | ms | 100 millisec. |
| Wait First Timeout | First waiting on the response after sending a call. | ms | 100 millisec. |
| Wait Timeout | Delay between the readings of a response until it is completed. | ms | 300 millisec. |
| Max Wait Retry | Number of retry response reading until it is completed. | - | 10 |
I/O tag configuration
...
I/O tag types: Ai, Ci, Co, Di, TiA, TiR.
The address is a number in the range from 0 to 300. The meaning of the addresses is stated in the Table 2:

| TiA | 6 | Time to reach peak NT. | R |
| TiA | 7 | Time of the last quarter-hour. | R |
You can obtain also the values from an archive of device per the current and previous month for both the main and secondary measurement. The reading of archive values may be started in the station dialog box or by Tell command
GETOLDVAL.
