? PURCHASING FAQ

1771-DXPS Procurement Checks

01 / MAIN MODULE
Can Allen-Bradley 1771-DXPS run without a 1771-DMC family module?

No. It expands a compatible 1771-DMC, DMC1 or DMC4 control coprocessor and requires the adjacent chassis position.

02 / PORT DATA
What serial settings must be captured before replacing Allen-Bradley 1771-DXPS?

Capture electrical mode, baud rate, framing, handshaking, device addresses, timeout behavior and exact cable pinouts for both ports.

03 / CHASSIS SPACE
How much chassis space is required for Allen-Bradley 1771-DXPS?

The main coprocessor occupies one slot and DXPS uses the adjacent slot, so the assembly requires two slots.

04 / PHYSICAL FIT
What compatibility checks matter for Allen-Bradley 1771-DXPS?

Confirm series, chassis placement, main-module type, front connectors, cable gender, RS-232/RS-422/RS-423 wiring and grounding.

05 / ACCEPTANCE
How should Allen-Bradley 1771-DXPS be accepted after replacement?
Verify power-up state, the four-character display, reset keyswitch, transmit and receive traffic on both ports, fault recovery and the main coprocessor application response.
