[🔗](https://github.com/Ultraluv/ex_iec60870/blob/main/lib/iec60870/apci_parameters.ex#L1)

APCI (Application Protocol Control Information) parameters for IEC 60870-5-104.
Corresponds to `sCS104_APCIParameters` in `lib60870-C`.

- `k`: Maximum number of unacknowledged I-format APDUs sent (default: 12)
- `w`: Latest acknowledge after receiving `w` I-format APDUs (default: 8)
- `t0`: Timeout of connection establishment in seconds (default: 10)
- `t1`: Timeout of send or test APDU in seconds (default: 15)
- `t2`: Timeout for acknowledges in case of no data messages (`t2 < t1`, default: 10)
- `t3`: Timeout for sending test frames in case of a long idle state in seconds (default: 20)

# `t`

```elixir
@type t() :: %IEC60870.APCIParameters{
  k: pos_integer(),
  t0: pos_integer(),
  t1: pos_integer(),
  t2: pos_integer(),
  t3: pos_integer(),
  w: pos_integer()
}
```

# `new`

```elixir
@spec new(keyword()) :: t()
```

Creates a new APCI parameters struct with optional custom overrides.
