How to recreate the state of an instrument in the station after it crashes

[marcosfrenkel]

Hello everyone, I am trying to make a recovery system for when an instrument crashes. Right now it is bringing my entire station down but I would like to implement a system where I can catch the failing instrument, re-instantiate it and keep my experiment running. However I am scared if I do that, the new re-instantiated instrument will not have the same values for all relevant parameters as I keep going. Any advice on how to handle this?

Could be instrument dependent, but generally re-instantiating an instrument shouldn't reset its parameter values. Should be the same as when you restart the kernel and bring up your station maintaining the state of the instrument parameters.
In any case, if you want to be sure that everything gets set to where it was, you can load the instrument state from the snapshot of the last dataset that was loaded onto the active database. The snapshot has all the values of all the parameters in the instrument at the time the dataset was created (i.e., at the start of the measurement)
