Good afternoon. I just wanted to get some clarification on compatibility.
If i purchase and install Control expert, i can use this on multiple M340 PLCs that have any old firmware versions. or do i need to get the specific software version. looking at the matrix it seems like just getting the latest version of control expert v15.3 will be compatible with 2.40 firmware on the m340.

i had a search for this topic but unable to see the correct information.

Yes you can. I have v15.3 program open right now with a 340 PLC running 2.50 firmware. There are options to change to older firmwares down to 2.00.
