I would like to know if anyone can help me with a question that I have with Profibus running on a ControlLogix PLC.
We are looking into installing a Profibus network in our facility, running on a ControlLogix PLC. I have heard of the SST-PFB-CLX-RLL card and I know that there is also a card from ProSoft.
My question is this:
After the initial installation of the Profibus system, our process will run 24x7x364 days a year (we only go down one day a year). We do not get shutdown times to add devices to the Profibus network very often. We could be adding Profibus DP or PA devices as time goes on. Can devices be added to Profibus on the fly without interrupting the communications to existing devices? I don't have the luxury of putting the PLC into Program Mode when a device is added. This is a big issue for us. In the old days, you just wired the device to an I/O card, and away you go. But I need to understand how a Profibus Master functions.
Can anyone get me some specifics on these moudules?
Thanks,
