Communication line configuration
...
- Communication protocols: UNIP, UNIP Input Only, UNIP Time Synchro, UNIP Input Only Time Synchro, UNIP SCAN.
- Station The station address is a decadis decimal number within the range 1...230, or a hexadecimal number with a hash at the beginning (e.g. #1A).
- The UNIP Time Synchro and UNIP Input Only Time Synchro protocols execute the real-time synchronisation synchronization for stations (time is included in pollthe request).
Note:
The UNIP SCAN protocol is a passive protocol that tracks the active communication of other another UNIP master/slaves system. It doesn't send polls , but decode decodes the tracking tracked communication.

Station protocol parameters
...
| Parameter | Meaning | Unit | Default value |
|---|
| Poll repetition Maximum count in case of of request retries. If no response returns after a request had been sent, the station's status will change to a communication error. | - | 3 |
| Delay between poll repetition in case of a communication errorTimeout before resending a request if no response has been received. | ms | 2000 ms |
| First waiting for response The delay after sending the request and before reading the pollresponse. | ms | 500 ms |
| Delay The delay between the response readings readings till its finalization. | ms | 500 ms |
| Repetition count of response readings till its finalizationThe maximum number of retries of the response reading. | - | 8 |
| First waiting for a response after writing, the ACK acknowledge is expected. | ms | 700 ms |
| Waiting for a response after a request to read archive data. | s | 1 s |
| In D2000 V5.00.017 Rel.A020430541, the interpretation of I/O tags of the AI and AO types of the forms of 3, 5, 6, and 7 has been modified to signed ones. The value of AIBC=YES enables backward compatibility and these I/O tags will be interpreted as unsigned. | - | NO |
| For the UNIP SCAN protocol only – time (in seconds) within which the response for a given station must be received, otherwise the station passes to a communication error. | s | 600 s |
Use Daylight Saving Time in TS Req. | Setting the parameter to YES activates the use of daylight saving time in the timestamped requests. | - | NO |
String A string containing the protocol parameters is being defined as follows:
Keyword=value;Keyword=value; ...
Example:
RC=1;RT=500;
If there is used a keyword with an invalid value in the initialization string , there will be used is used, a corresponding default value according the to table 1 will be used.
