| The start address of Event data. The data is 4 words in length, the data are 32-bit binary numbers (containing 10-bit SPACOM Unit Number, 7-bit Channel Number and 5-bit Event Number which can be specified in the I/O tag configuration) with a time stamp. | - | 2400 |
| The size of the block of data specified in the BLOCK_READ data request sent by the KOM process (2-244 bytes). | bytes | 100 |
| A period (10-1440 minutes) in which the D2000 KOMprocess performs readout of all data (integrity readout). | min | 15 |
Diagnostic Request Timeout | A period (10-60 sekúndseconds) in which the D2000 KOMprocess sends a diagnostic request (DIAG_LOOP) to verify line functionality. | s | 5 |
String A string containing the protocol parameters is defined as follows:
...
If a keyword with a valid value is not found in the initialization string, there a corresponding default value will be used (see the table above).
...
- Word Address: 16-bit data address in device memory (0-65535) used during readout of all data (see Read Data Timeout).
- SPACOM Unit (Di tags only): optional 10-bit address of SPA Unit (0-1023) within the SPACOM system.
- Channel (Di tags only): optional 7-bitová adresa bit address of SPA Channel (0-127) within the SPACOM system.
- EventNr 0->1 (Di tags only): optional 6-bit number of Event (0-63), that will cause transition to True value True.
- EventNr 1->0 (Di tags only): optional 6-bit number of Event (0-63), that will cause transition to False value False.
Note: Optional address items SPACOM Unit, Channel, EventNr 0->1, EventNr 1->0 are used when the Di I/O tag§s tag's value is to be set after the arrival of Event Data.
