Please respond with guidance on where to find an interface to connect a Modicon Quantum PLC processor to the existing Allen-Bradley 1771 racks.

Looking for a product to preserve the wired I/O.
Contact your AB rep. AB has encompas(r) partners (3rd party certified solution providers) that have solutions for these kinds of problems.

Dear friend,

Take a look at The company SS Technologies has a product called X-LINK, which can be a bridge between many different networks.

They have Allen Bradley Remote I/O and Modbus TCP/IP, Modbus Plus or Modbus options availables.

He had already used here in Brazil Modbus Plus with Devicenet and it worked fine.
