Heidolph MR Hei-Connect

The Heidolph MR Hei-Connect magnetic stirrer can be controlled via RS232 using the HeiConnect device type. The implementation uses the extended interface protocol described in the official operating manual.

Configuration

Real hardware:

[device.hei-connect]
type = "HeiConnect"
port = "COM1"
connection_check = true

Simulation:

[device.hei-connect-sim]
type = "SimulatedHeiConnect"

Note

Serial connection parameters The following serial parameters are used by default:

  • timeout 1 s

  • baudrate 9600

  • parity even

  • stopbits 1

  • bytesize 7

Further parameters accepted by serial.Serial can be specified in the device configuration.

API methods

The device exposes three components:

  • stirring-control to set/query speed and start/stop rotation.

  • temperature-control to set/query temperature, start/stop heating, and select fast or precise heating mode.

  • control to query status and software version.

temperature-control-mode is read-only and reports whether the device is controlling temperature from the hotplate or from the external Pt1000 sensor.

The operating manual is available from Heidolph.
