Data Array
Data array can store up to 800 data (0…799) with each data size of 32-bit. It can
be used to store the high-speed captured data and high-speed compared data as
well as E-Cam curves. Users have to segment the space for these three functions as
their individual spaces are not restricted in the default setting. This way data
being overwritten or changed incorrectly can be avoided. You can set ID193
(P2.008) to 30 and then 35 or use the KNX5100C configuration software to
write the data to EEPROM, otherwise, the data does not remain after power off.
A user-friendly setting screen is also provided in the configuration software for
reading / writing the data array. See Set Up Capture and Compare in
KNX5100C Software on page 329 .
With two channels provided, users can use panel, communication, or the
configuration software to read data from or write data to the data array. Channel
1 can be set by ID304 (P5.011), ID305 (P5.012), and ID306 (P5.013).
ID304 (P5.011) specifies the address for reading / writing of data array. ID305
(P5.012), and ID306 (P5.013) are the windows of reading / writing. Both can be
used to read / write, but the behaviors after reading / writing differ. See
Table 106 . Channel 2 can be set by ID304 (P5.011), ID388…ID391
(P5.100
…
103).
ID304 (P5.011) sets the address for reading / writing of data array. ID388
(P5.100) can read data from or write data to the data array address following the
address set by ID304 (P5.011). ID305 (P5.012), and ID391 (P5.103) work the
same way. If the address number has reached the max. 799, then the address
remains 799 instead of adding up. You can find more details in Table 106 .
Example: When using the drive panel or communication for reading from or
writing to the data array, add values to the data array address in this order:
• Data array #11 = 100,
• Data array #12 = 200,
• Data array #13 = 300.
