12 + ## Usage
13 +
14 + ABex is a GenServer-based implementation to expose tags and can be summarized by:
15 +
16 + 1. Start a Tag process use `start_link/1`.
17 +
18 + The following options are available:
19 + - `ip` - IP PLC address (string).
20 + - `path` - The path to the device containing the named data (string).
21 + - `cpu` - AB CPU models (string): plc,plc5,slc,slc500,micrologix,mlgx,compactlogix,clgx,lgx,controllogix,contrologix,flexlogix,flgx.
22 +
23 + 1. Send requests `get_all_tags/1`, `read/2`, `write/2`.
24 +
25 + ### Get Tags paths.
26 +
27 + To get all available tags use `get_all_tags/1`.
28 +
29 + ```elixir
30 + iex> {:ok, tag_pid} = ABex.Tag.start_link(ip: "20.0.0.70", cpu: "lgx", path: "1,0")
31 + iex> {:ok, tag_list} = ABex.Tag.get_all_tags(tag_pid)
32 + ```
33 +
34 + ### Read tag data
35 +
36 + Use `read/2`. The following options are available:
37 + - `data_type` - Expected data type (string).
38 + - `elem_size` - Expected data type size in bytes (integer).
39 + - `elem_count` - Number of items to request (integer).
40 + - `name` - Tag's name (string).
41 +
42 + ```elixir
43 + iex> {:ok, tag_pid} = ABex.Tag.start_link(ip: "20.0.0.70", cpu: "lgx", path: "1,0")
44 + iex> {:ok, values} = ABex.Tag.read(tag_pid, name: "Some_tag", elem_size: 8, elem_count: 1, data_type: "uint8")
45 + ```
46 +
47 + ### Write a value to a tag
48 +
49 + Use `write/2`. The following options are available:
50 + - `data_type` - Expected data type (string).
51 + - `elem_size` - Expected data type size in bytes (integer).
52 + - `elem_count` - Number of items to request (integer).
53 + - `name` - Tag's name (string).
54 + - `value` - Value to be written on the tag.
55 +
56 + ```elixir
57 + iex> {:ok, tag_pid} = ABex.Tag.start_link(ip: "20.0.0.70", cpu: "lgx", path: "1,0")
58 + iex> :ok = ABex.Tag.read(tag_pid, name: "Some_tag", elem_size: 8, elem_count: 1, data_type: "uint8", value: 103)
59 + ```
