Replacement & Compatibility FAQ
Q: Can I replace IC697CPU771 with IC697CPU782 without changing the rack?
A: Yes. The IC697CPU782 is a direct slot-compatible upgrade. You will need to re-download your program and update any Ethernet configuration.
Q: Is IC697CPU771 still in production?
A: GE Fanuc has discontinued active production of the Series 90-70 line. Konmask.com supplies new-surplus and refurbished units with full testing.
Q: What programming cable is required?
A: Use an RS-232 serial cable (IC690ACC901 or equivalent) with Proficy Machine Edition or Logicmaster 90-70 software.
Q: Can IC697CPU771 communicate with modern SCADA systems?
A: Yes, via SNP/SNPX protocol or by adding a dedicated Ethernet module (IC697CMM741) to the same rack.
Q: What is the difference between IC697CPU771 and IC697CPU772?
A: The IC697CPU772 doubles the user memory to 1 MB. All other hardware and backplane interfaces are identical.
