Appears to be about the same code as what I downloaded from the PLC to make changes and upgrades to.</div>

I think you will find Cleo_V4.acd that I passed along to be well advance in HX controls and valve naming.</div>

As the code is only having to control one magnet instead of five, I have reduced the HX controls routine from the SHMS controls. I'm sure there will be further changes as the project moves along. I can see that JT7 (sheet31) can be simplified as it only needs
to respond to temperature but how this valve needs to respond to interlocks remains to be determined.</div>

It is rather simple to upload a different code, test and verify, then re-upload the code that was previously in the PLC.</div>

Where can I get a copy of the latest code, just downloading it from the PLC , may not bring in all comments and descriptions.</div>

If your Cleo_V4 acd file contains all changes on which DSG has being working on, there should be no problems.</div>

Unless is something necessary which can not be made online, I would suggest to upload your changes online, import routine instate of replacing the current acd file running in the PLC, so then we can ensure that nothing is missed.</div>
