We're a 90% mitsi site, and recently have been forced to purchase some 'off the shelf' machines with S7 PLC's in them.
To now, we have used contractors for any PLC work but recently we purchased a laptop and software to connect ourselves. Training is happening in 2017, but:
1. 1 machine we're trying to upload from as a back up has password protection - is there a way around this?
2. We're told that you can't upload a HMI program from a Siemens HMI, and you can only edit if you have the original/most recent software before hand - is this true, as we're in the state where we want to back everything up.
3. Is there anyone who's mitsi & siemens capable who would be willing to answer my silly questions over the next few months haha... thanks.
