SLC Module - 1747-M13

Right now I'm looking at adding extra memory to a SLC 5/03 (1747-532) plc we have. What I need more memory for is recipes for data. I came across the 1747-M13 and am wondering if this could work for me. I'm not sure if it can because from what I have read about it, I don't belive you can update this memory while the PLC is in run mode which I don't want, correct me if I'm wrong on this.

My question is could I use this module store the extra data? I know I could upgrade the processor to the 532 (32k) but that still isn't enough.

Also, is there any other way of doing this? I know a more advanced way would be to store the information on our network server and using a database, but am wondering if there is something else out there I could do.

Leeroy,

from what i read about the module, this is an eprom module to store the program, not additional cpu memory. i may be wrong and hopefully someone will correct me if i am.

goto the ab website and search for that pert number.

James,

After looking at the ab website, yes you are right on storing the program. Since it's an eprom module, I think I was right about writing to it while the PLC is running.

Edit: I think I'll do just that Ken, we already have one way in mind.

James is right; those are nonvolatile storage, not memory expansion. In general, most PLCs have a fixed amount of onboard memory.

Your instinct to save recipe data on an external computer is, I think the right one. There are dozens of HMI and database connectivity programs that support A-B controllers. If you're interested in investigating that here on the Forum, go ahead and start a new thread and post some information about your recipe and HMI needs.
