pyhoff.devices.BK9100#
- class pyhoff.devices.BK9100(host, port=502, bus_terminals=[], timeout=5, watchdog=0, debug=False)#
Bases:
BK9000
BK9100 ModBus TCP bus coupler
Instantiate a new bus coupler base class.
- Parameters:
host (
str
) – ip or hostname of the bus couplerport (
int
) – port of the modbus hostbus_terminals (
Iterable
[type
[BusTerminal
]]) – list of bus terminal classes for the connected terminalsdebug (
bool
) – outputs modbus debug informationtimeout (
float
) – timeout for waiting for the device responsewatchdog (
float
) – time in seconds after the device sets all outputs to default state. A value of 0 deactivates the watchdog.debug – If True, debug information is printed.
Examples
>>> from pyhoff.devices import * >>> bk = BK9000('192.168.0.23', bus_terminals=[KL3202, KL9010]) >>> t1 = bk.terminals[0].read_temperature(1) >>> t2 = bk.terminals[0].read_temperature(2) >>> print(f"Temperature ch1: {t1:.1f} °C, Temperature ch2: {t2:.1f} °C") Temperature ch1: 23.2 °C, Temperature ch2: 22.1 °C
- add_bus_terminals(*new_bus_terminals)#
Add bus terminals to the bus coupler.
- Parameters:
new_bus_terminals (
Union
[type
[BusTerminal
],Iterable
[type
[BusTerminal
]]]) – bus terminal classes to add.- Return type:
list
[BusTerminal
]- Returns:
The corresponding list of bus terminal objects.
- get_error()#
Get the last error message.
- Return type:
str
- Returns:
The last error message.
- select(bus_terminal_type, terminal_number=0)#
Returns the n-th bus terminal instance of the given bus terminal type and terminal index.
- Parameters:
bus_terminals_type – The bus terminal class to select from.
terminal_number (
int
) – The index of the bus terminal to return. Counted for all bus terminals of the same type, not all bus terminals. Started for the first terminal with 0
- Return type:
TypeVar
(_BT
, bound= BusTerminal)- Returns:
The selected bus terminal instance.
Example
>>> from pyhoff.devices import * >>> bk = BK9050("172.16.17.1", bus_terminals=[KL2404, KL2424]) >>> # Select the first KL2425 terminal: >>> kl2404 = bk.select(KL2424, 0)
