When I change a hardware structure, Can I save the variables the old hardware?
The replacement of Ethernet sources and modules have succeeded, but to replace clusters (CI830 by CI840), I have to delete all of the tree clusters and insert the module I / O again. So far so good, except that in doing so I am losing all variables and description allocated to each channel of each I / O module.
Is there any way to export the list of variables, treat Structure Hardware and then import again? Or some other way without me having to allocate the inputs and outputs one by one again?
I assume You are using the gsd file configuration, right?
If all You need to copy is the IO configuration, then I would suggest copy-paste method. It's not very nice, but as You can't move entire module configuation, this at least will move the IO editor configuration.
Add the new cluster and it's modules according to configuration in old one.
Open the IO Editor for the old IO module > select all rows > right-click > Copy > close the IO Editor > delete the OLD module > open IO Editor of the newly added module, that corresponds to the deleted one > right-click > Paste.
You need to delete the old module before pasting the configuration, because one variable cannot be assigned to multiple IOs. Make sure You made a copy correct before deleting!
Hope this will help a little,
