Posted 12 Apr 2022 Hi all, My customer is looking to upgrade a HE iFIX SCADA V5.5 to V6.5. The PLC is to remain which is an Allen Bradley CompactLogix L33ER CPU. I am finding it difficult to get information in terms of compatibility - i.e is iFIX V6.5 compatible with the L33ER CPU or are there any known bugs. If anyone has any info on this it would be greatly appreciated. Thanks Share this post Link to post Share on other sites
