Somebody has surely tried this since 2008. Any updates?
I have a couple PV+ terminals that I need to upgrade the memory/cf on. I have been thinking about just spending the $50 and ordering a 256mb SO-DIMM and a 256mb cf card and give it a shot. AB wants like $800 for the 128mb versions.
How much will it cost if the cheap stuff fails?
For HMI stuff, I will use generic parts, but for say a CF card in a controller, give me the hardened vibration and high temp. tested A/B brand. The extra $100 could be gone in seconds should the PLC fall over and die because I used a $17 memory card.
So if this HMI is one that you have a spare and isn't going to kill the whole plant due to a problem, then go cheap, otherwise, pay now instead of later.
Just my opinion.
