# devices.horst:HTMC11


Instrument class for the Horst HTMC11 bakeout controller.


Usage

``` python
devices.horst:HTMC11(
    portname,
    slaveaddress,
    baudrate=115200,
    request_delay=0.02,
    write_delay=0.1,
    startup_delay=0.5,
)
```


connection is made via a RS485 serial line which uses the Modbus RTU protocol.

### \_\_init\_\_()


Initialize Horst HTMC11 bakeout controller.


Usage

``` python
__init__(
    portname,
    slaveaddress,
    baudrate=115200,
    request_delay=0.02,
    write_delay=0.1,
    startup_delay=0.5,
)
```


#### Parameters


`portname: str`  
Name of the serial port to connect to

`baudrate: int = ``115200`  
Serial communication speed in baud. Default is 115200

`request_delay: float = ``0.02`  
Minimum time in seconds between Modbus requests. Default is 0.02.

`write_delay: float = ``0.1`  
Minimum time in seconds between Modbus writes. Default is 0.1.

`startup_delay: float = ``0.5`  
Time in seconds to wait after opening the serial connection before the first register request. Default is 0.5.
