Mixed-plugins for actuators and viewers

[Ashwolaa]

Hi everyone,

I am currently developing a plugin for a LakeShore Controller (model 340).

This apparel consists in:

• a viewing part which effectively gives the temperature of up to four sensors
• a resistive heating part which will deliver a current to heat up some parts in the setup

Currently, I am able to connect with it through a serial connection and I am using some parts of the pymeasure library

Intially, I planned to make a DAQ_move giving it as an input a temperature setpoint to reach and monitoring the temperature evolution to decide if the motion has been achieved or not.

However, I though that it would also be interesting to use it also as viewer to measure the temperature in real time.

In conclusion, I would like to use it both as an actuator and a viewer but I have a single connection. I believe this type of approach could be generalized to many instruments and I would be interested to know your thoughts on the subject and if you have maybe some ideas on how to deal with it

Sure you can do it easily with the concept of master/slave that is also generalised for any control module that can share the same controller, the pymeasure driver in your case

Yes, one good example is the Keithley by NTappy which is an amperemeter and a voltage source at the same time!

Thanks for the fast answers, I will look through the example and the master/slave definition
