Snapshot function

[Paras-Bajra]

Hi Jasper,

I wasn't able to create a snapshot. Is this function still under development?

I'm using the latest version v0.1.5 with PLCSIM Adv v6.0

Regards,

Hi @Paras-Bajra,

Thanks for creating an issue!

The snapshots functionality is implemented but the instance needs to be powered off.
Can you power off the instances you want to take snapshots from and try again please. If that does not work, can you elaborate with some printscreen on what you see.

Ps: don't hesitate to give feedback!
Reading back my last comment, I'm wondering whether snapshot is the best name for this feature.

Thanks for the quick response.

I can take snapshots while the instance is powered off but I'm not sure how to use this function properly. Is this snapshot function similar to snapshots in SIMIT?

I was expecting this function to be available while the instance was powered ON so i can save and restore the system to know state while being online to the PLC.

The idea is that it takes a "snapshot" of the SW+HW that is loaded in the PLC instance. This way you can e.g. download different versions of PLC code to the PLC instance, take a snapshot and easily switch between versions.

I can see why it is misleading and should probably rename it to archive or something similar..

I have no experience with the snapshot functionality of Simit, but I'm guessing it saves all the values of the variables at a certain point and you can then reload it afterwards? Is this the functionality you are looking for?

Ah ok. It makes sense how you've implemented the snapshot/archive function.

And yes, with snapshot function in SIMIT, it basically allows to save all the values so you can reload it afterward.
