Hello guys,
I need to add in a few discrete and analog cards for an existing 1769 Compact Logix system at a local Treatment Plant for an expansion project. The existing rack has address reserve cards installed that I've never dealt with. In previous experiences, in order to add new cards, I would take the following steps.
1.) Save a copy of the existing project and power down the PLC.
2.) Pull off 1769 compact logic locking tabs for the end plate and insert new cards at the end of the rack as to avoid any address changes or conflicts on the program. (Make sure end plate gets put back on).
3.) Power the system back up and Hop online with the processor and edit the I/O config and the new cards firmware revisions to match the new cards.
4.) test out the I/O on the newly installed cards.
Since the address reserve cards are in the middle of the rack, is there anything special I need to know about them or am I basically just installing the I/O cards in the address reserve space instead of at the end of the rack as stated in step #2. The way I see it the address reserve cards are put in place to be able to add in new Discrete Input cards beside existing ones, Add in new Discrete Output cards beside existing ones, and add in new analog cards beside existing ones so they're more organized and not at the end of the racks.
Any input is much appreciated.
Regards,
Tex
