### Address Format

> AREA ADDRESS\[.BIT]\[.LEN\[H]\[L]]

#### AREA ADDRESS

| AREA | TYPE | ATTRIBUTE  |  REMARK                                  |
| ---- | -------- | ----- | -------------------------------------- |
| X    | bit      | read/write | Input relay (FX3U)                |
| Y    | bit      | read/write | Output relay (FX3U)               |
| M    | bit      | read/write | Internal relay (FX3U)             |
| S    | bit      | read/write | Status relay (FX3U)               |
| TS   | bit      | read/write | Timer Contact (FX3U)              |
| CS   | bit      | read/write | Counter Contact (FX3U)            |
| TN   | all      | read/write | Timer Current value (FX3U)        |
| CN   | all      | read/write | Counter Current value (FX3U)      |
| D    | all      | read/write | Data register (FX3)               |

#### .BIT

Only available for **non-bit type area**, means read the specified binary bit of the specified address, the binary bit index interval is [0, 15].

| Address  | Data Type |  Description                      |
| ----- | -------- | -------------------------- |
| D20.0 | bit      | D Area, address 20, bit 0 |
| D20.2 | bit      | D Area, address 20, bit 2 |

#### .LEN\[H]\[L]

When the data type is string type, **.LEN** indicates the length of the string; you can optionally fill in **H** and **L** to indicate two byte orders, and the default is the byte order of **H**.
