# Address syntax for non-named addresses

Addresses without names can be addressed directly using the format:

    n:0xA [Format]

Part | Description
--- | ---
n | Table number. See the section below titled "Table types" for table descriptions and their number.
A | Address within the table (in hexadecimal).
Format | (Optional) Only used for Input and Holding register tables (3 and 4). If a format is not specified, the format defaults to IEEEFP.

For signal tags above 1,000, you must use hexadecimal addressing.

## Table types

ATTENTION: For controllers with a Data Table setting of Holding Registers Lower or Holding Registers Upper, you can only use Table 4.

Table Description | Table Number | Point Type | Address Type
--- | --- | --- | ---
Digital Output (also known as Coil)1 See the topic titled "Troubleshooting problems with specific controller models." | 0 | Status | Source/Destination2 See the topic titled "Digital output control strategies."
Digital Input | 1 | Status | Source
Input Registers | 3 | Status/Analog/Accumulator | Source
Holding Registers (Upper and Lower) | 4 | Status/Analog/Accumulator | Source/Destination

## Non-named address examples (for HC900)

Parameter | Point Type | Address Type | Point Table/Address/Format | Controller OFFSET Address3 Offset is not required for controllers with a Data Table setting of Holding Register.

Signal Tag 1001 | Analog | Source | 4:0x4330 IEEEFP | 4,000

Analog In, Slot 2, Channel 2, of Rack 24 For controllers with a Data Table setting of Holding Registers Lower or Holding Registers Upper, DO and DI cannot be used. See the sections "Digital Output values" and "Digital Input values" in the topic titled "Address syntax for named addresses." For controllers with a Data Table setting of All Tables, all I/O beyond Rack 1 in an HC900 must be addressed using hexadecimal addressing while all I/O in Rack 1 can be accessed using DI, DO, and AI named addresses. For example, D1 9, AI 18. See the HC900 Hybrid Controller Communications User Guide (part # 51-52-25-111) for a listing of I/O hexadecimal addresses.
