This protocol supports the following Landis&Gyr devices:
Table 1
Device type | The version of the software in the device | Protocol version |
---|---|---|
PRU1.64, RWP80 | TOCCATA1 V.0 | |
PRU1.64, RWP80 | TOCCATA1 V.1 | |
PRU10.64, PRV2.128 | TOCCATA2 V.0 | |
RWP80 | AZA v. 07.10 | TOCCATA1 V.2 |
You can define the following parameters:
Table 2
Keyword | Full name | Meaning | Unit | Implicit value |
---|---|---|---|---|
RC | Retry Count | The number of request retries if the communication error occurs. | - | 1 |
RT | Retry Timeout | The delay between repeating the request if the communication error occurs. | ms | 1000 millisec. |
WFT | Wait First Timeout | The first waiting before reading the response after the request is sent. | ms | 300 millisec. |
WT | Wait Timeout | The delay between response readings until the response is completed. | ms | 300 millisec. |
MWR | Max Wait Retry | The number of response reading retries until the response is completed. | - | 12 |
WBR | Wait Before Request | The delay that is used before each request. | ms | 0 |
KPX | KPX Route | The communication via the communication concentrator. The station address is used. | YES/NO | NO |
MPI | Maximum PA Items | The maximum number of PA data in one data block. You must always define an even number. If communicating via concentrator, the maximum number is 10, otherwise, it is 24. | - | 10 |
LE | Log Events | It allows saving the text messages to TRACE.LOG from the device. This file is in the current working directory of the communication process. | YES/NO | NO |
KLRD | KL Read Delay | The time period to obtain the values of KL data. KL data are read when starting the communication process and again after elapsing of the KLRD period. | min | 30 minutes |
SACK | Send ACK | Sending ACK message (DLE-ACK) after the D2000 KOM receives the proper packet. A direct connection requires to set YES. Connection via concentrator (KPX=YES) requires to set NO (speeding up of communication). | YES/NO | YES |
SENAC | Send Enhanced ACK | Sending enhanced ACK message with station address (DLE-ACK-CR-LF-StationAddress-CR-LF) after the D2000 KOM receives the proper packet. | YES/NO | NO |
PRUV | PRU Version | TOCCATA protocol:
| 0, 1, 2, 3 | 0 |
PAF | PA First | At starting the communication, it gives priority to reading the PA instead of KL parameters. KL parameters will be read after PA ones are received from all stations. | YES/NO | NO |
FD | Full Debug | Activation of the debug information about received values. | YES/NO | NO |
A string containing the protocol parameters is defined as follows:
Key_word=value;Key_word=value; ...
Example:
RC=1;RT=500;KPX=YES;
If there is used a keyword with an invalid value in the initialization string, there will be used corresponding default value according to the table 1.
I/O tags: AI, AO, CI, CO, DI, DO, TIR, TOR, TIA, TOA.
In the configuration you must define the following parameters:
-
