*2. Address selection rule is as follows.
*3. Allocate the System Area above the file number 7 integer file. It will not operate with file number 10 and above. You must construct an area
above the SLC 500 data table file that corresponds to the System Area Address set by WindO/I-NV2.
The input and output addresses are made up of the slot number and the word number.
- The address makeup is as follows:
Bottom digit: Word number
2nd and 3rd digits from the bottom: Slot number
- If the module in the slot has 16 or fewer points, the word number is 0, and if it is a 32-point module, the word number is 0
for the lower word
(bit 0 to bit 15) and 1 for the upper word (bit 16 to bit 31).
- In the case of a rack-type controller, the slot number is attributed as is, and in the case of a package-type controller, it is as
follows.
Package-type controller: 0
Left slot of the expansion rack: 1
Right slot of the expansion rack: 2
Example:
Address specification with SLC 500: I: 1.0
Address specification with WindO/I-NV2: 1 0
- You cannot directly write to inputs and outputs.
- A communication error will occur if you specify a file or element that is not allocated to the SLC 500 data table map.
