Communication station configuration
...
- Communication protocol: L&G TOCCATA via UNIP2
- Station address is configured in KPX-02.
...
Communication station - configuration dialog box - "Protocol parameters" tab.
These parameters influence some optional parameters of protocol. You can set the following station parameters:
Table 1
| Parameters used for UNIP2 communication with KPX-02 (locally). |
| Key word | Full name | Meaning | Unit | Default value |
|---|
| Routing Address | The original address of the station for which the data was received by routing. | - | 0 |
| Retry Count | Number of repeat calls if the communication error occurs. | - | 2 |
| Retry Timeout | Delay between repeating the call if the communication error occurs. | ms | 100 |
| Wait First Timeout | First waiting for the response after sending the call. | ms | 100 |
| Wait Timeout | Delay between reading the response until it is completed. | ms | 100 |
| MTU For Sending | MTU (maximum transmission unit) for sending data. | bytes | 240 |
| MTU For Receiving | MTU (maximum transmission unit) for receiving data. | bytes | 240 |
| Max. Wait Retry | Number of retry response reading until it is completed. | - | 20 |
| Wait Response Delay | The period, after writing, during which D2000 KOM keeps communicating with the station to obtain the confirmation of successful write. | sec | 0 |
| Parameters that configures data acquisition by TOCCATA protocol in KPX-02 device (transported). |
| Key word | Full name | Meaning | Unit | Default value |
|---|
| Max PA Items | Maximum PA data in one data block. | 2 to 12 | 10 |
| KL Read Delay | Delay between the reading of KL points. | min | 2 |
| Max Errors | Maximum errors in communication with L&G device. When this value is exceeded, all data will become invalid. | - | 4 |
| Retry | Number of retries of one call for data from L&G device. | - | 2 |
| Timeout | Absolute time necessary to read the response form L&G device. | ms | 3000 |
| Tx Delay | Delay of sending the response from the communication device after receiving the call. Useful only for RMMBX radio modems. | x10 ms | 15 (150 ms) |
| PRU Version | Version of TOCCATA protocol. It is the same as in L&G TOCCATA protocol. | 0, 1, 2, 33 | 0 |
String containing the protocol parameters is defined as follows:
Key_word=value;Key_word=value; ...
Example:
WT=100;MWR=20;
If there is used a keyword with an invalid value in the initialization string, there will be used corresponding default value according the table 1.
