<div class="markdown_content"><p>No you can not save the online values, however you can save values on a sd card <br/> anytime the program is changed the values will be reset, see manual on retain.</p></div>

<div class="markdown_content"><p>You could also use the: 'Watch- and Recipe Manager'. Here you can add a new watch list and type in all the retained variables you like to save on your laptop. Now when you go online with your PLC, you can click: 'Read Recipe' and you have a copy of all the data in the PLC. </p> <p>Now when you lose all the data in the PLC you can easily restore it by writing the recipe back to the PLC.</p> <p>Good luck!</p></div>

<div class="markdown_content"><p>Hi<br/> For ABB AC500 the value of the retain variables could be saved and load from a SD card with help of "saveretain" and "restoreretain" in the PLC browser.</p> <p>You could then backup all values to a standard SD card and then restore them when needed. </p> <p>Check out chapter "13.2.5 Storing and Loading Retentive Data to/from an SD Card" in the "Target system" part of the help file.</p> <p>Regards<br/> Johan</p></div>

<div class="markdown_content"><p>Guys I need some help with this. I've again lost all parameters. <br/> It goes like this: at some point when I try to download I get a Communication Error (#0) logout performed. I can ping the plc, I can go online but if I try to download I always get this.<br/> I can reset the plc but it doesn't help. When I switch it off and on the previously loaded boot project doesn't run and I lose everything. Then I can download normally and everything works ok till next time that this problem starts (unknown cause).</p></div>

<div class="markdown_content"><p>Hi, I'm using an ABB 500 plc (PM591) and I've already lost a few times all my parameters.<br/> I set the variables I want to keep as "retain persistent" and I create an online boot project so in normal situation it's ok. But if something goes wrong (it already did more than once) I want to have a backup on my pc.<br/> Is there a way to save the online boot project also on my pc? Because I think the boot project created offline doesn't have the right values of the variables.</p></div>
