Help on Updates

[Crazy35111]

It has be a long time since I have updated the firmware on my unit. Can I do the very latest update and be good, or do I need to go through at install all the missed updates?

you can go the the latest one.
Just load the FW with the old PLC and then connect with the new plc to the new FW

going from FW 4.X to 5.X you can't use the settings file since they are not compatible. so then you have to do reconfigure by hand.
if you stay within the 5.X you can have some error when importing the setttings files , but if you do a quick check of the settings you will be ok.
