I recently had a processor have a major fault due to a power failure (which is another concern of mine) and when I went to go online with it alerted me that the program I am trying to load with is different than the program currently on the processor. Now I am the last person on this processor and have the most current file. I uploaded this program off the processor because now my curiosity is peaked and it is completely different than the one that was running on it before this major fault??? My question is can a processor have more than one program loaded on it (since I was under the assumption it can only have one) at once and if so how can I direct it to put the program I want it to load in after a fault. Or can I remove this other program all together.  Next question is regarding this power failure fault... The processor is wired from a 24vdc panel and the panel is fed from a bank of batteries being charged from a La Marche battery charger constantly as long as there is line power. The battery bank gives enough time for the e-gen to start and give power back to the charger. With this set up the PLC never sees a power failure so how can the processor then fail?    If anyone has had any experience with this I would love to here how you corrected it or if there is even a correction to be made. Thanks :)

Hi, Im new to the Crimson software and need to configure the communications protocol for 485 modbus and Emerson Process ROC Protocol Enhanced TCP/IP. My question is for the 485 modbus do I need to create blocks for the holding registers I need to pull off the device or can I just map the tags to the modbus address? If I need the blocks, when I create the tags and reference the modbus address is it pulling from the blocks I created? As for the Emerson Process ROC Protocol Enhanced TCP/IP when I select it what is the Host Identification referencing? The Device under the protocol has its own Identification. Do I need to change both to the same group and unit number so it will address the device? I have attached screen shots of the Protocol for the TCP/IP device in question. Any help would be great. Thank You
