Address

Enter the point address of the data as follows:

region[record].attribute

Where:

region specifies the point type from the table.

record is the index within the region.

attribute specifies what information about that record is to be processed.

For example, to access the value of the Analog Input 3, configure a point with the address:

AI[3].VALUE

If you do not specify an attribute, the current value is assumed. Thus, the previous example is equivalent to:

AI[3]

For Unitary Controllers, the record range is 1–256. See Point Types for the record number ranges in each DX9100 region.

Update Criteria

The update criteria determines how the data will be requested.

Select On Change or On Scan for points whose values should be polled by Johnson Controls N2 Bus Communications at regular intervals.

Select On Demand On Scan or On Demand On Change for points whose values should be polled by Johnson Controls N2 Bus Communications at regular intervals while users are viewing them.

Address Offset

Enter the bit offset that corresponds to the bit position within the word.

The valid range for bit offset is 0-15, where 0 is the least significant bit. The bit offset must be specified as a decimal value.

For binary I/O on Unitary Controllers, the bit offset for a point is always 6.

For binary inputs on a DX9100, the bit offset is one less than the remainder from dividing the record number by 8. For example, BI[1] is at bit offset 0 and BO[45] is at bit offset 4 (45 % 8 = 5. 5 – 1 = 4).

For the first 8 binary outputs on a DX9100, consult the table on page A­3. For binary outputs 9 and above, the bit offset is one less than the remainder from dividing the record number by 8.
