Eurotherm 2200 Furnace Controller

class nupylab.drivers.eurotherm2200.Eurotherm2200(port: str, clientaddress: int, baudrate: int = 9600, timeout: float = 1)

Bases: Instrument

Instrument class for Eurotherm 2200 series process controller.

serial: pySerial serial port object, for setting data transfer parameters.

Connect to Eurotherm and initialize program and setpoint list.

Parameters:

port – port name to connect to, e.g. COM1.
clientaddress – integer address of Eurotherm in the range of 1 to 254.
baudrate – baud rate, one of 9600 (default), 19200, 4800, 2400, or 1200.
timeout – timeout for communication in seconds.

property active_setpoint: int: Active setpoint. 1 = SP1, 2 = SP2.

property dwell_time: Dwell time after ramping from SP1 to SP2.

property end_type: Go to state at end of program.

property operating_mode: str: Control operating mode. Valid options are auto or manual.

property output_level: float: Power output in percent.

property process_value: float: Process variable.

property program_status: Program status. Writable values are`reset` or run.

read_float(registeraddress: int, functioncode: int = 3, number_of_registers: int = 2, byteorder: int = 0) → float: Convert to higher register to properly read floats.

read_time(register: int) → float: Read time parameters in seconds.

property setpoint1: float: Do not write continuously changing values to this variable.

property setpoint2: float: Do not write continuously changing values to this variable.

property setpoint_rate_limit: float: Ramp rate limit.

property target_setpoint: float: Target setpoint (if in manual mode).

property working_setpoint: float: Working set point. Read only.

write_float(registeraddress: int, val: float, number_of_registers: int = 2, byteorder: int = 0) → None: Convert to higher register to properly write floats.

write_time(register: int, val: float): Write time parameters in seconds.
