The number of elements for structured I/O tags with configured Destination column. Every read element (1,2,3 .. items) will be written to one item of the destination column.
Note: All "items" elements are read at once. If e.g. 100 elements of device type (device code) which has data of word type (e.g. address D10, WORD, 100), are configured, it means reading of a block of 200 bytes. If the number of objects is greater than the value of the Max Points, parameter, or the data size is greater than the Max Data Bytes, the reading will not be performed and an error message Too many elements in point < I/O tag name> will be added to the line log.
Configuration examples:
- X10 - Input 10, interpreted as a BIT (default)
- D0 - Data register 0, interpreted as a WORD (default)
- M12, WORD - Internal relays 12-27, interpreted as a WORD
- D4, REAL - Data registers 4 and 5, interpreted as REAL
- Y10, BIT, 20 20 - Inputs 10-29, interpreted as BIT (default), assigned to 20 items of the Destination column
- D4, REAL, 10 - Data registers 4-23, each couple interpreted as REAL, assigned to 10 items of the Destination column
- D4, WORD, 10 - Data register 4-13, interpreted as WORD, assigned to 10 items of the Destination column
