PLC ARCHITECTURE & SELECTION

Allen Bradley Plc control decisions, documented before procurement

Define controller capacity, I/O topology, EtherNet/IP traffic, enclosure conditions, and migration constraints in one engineering conversation. Our specification-led process helps controls engineers and panel builders distinguish a viable platform from a convenient part number.

THREE-PART SPECIFICATION

Build the bill of material around the control task

PLC controller rack

Controller Platforms

Size memory, task execution, local expansion, and redundancy requirements without assuming that every controller family supports the same operating envelope.

CPU · Memory · Task load
distributed IO modules

Local and Distributed I/O

Map digital, analog, specialty, and safety signals to wiring distance, update rate, isolation needs, and maintenance access.

I/O count · Isolation · Topology
industrial network module

Network Interfaces

Confirm EtherNet/IP, Modbus TCP, gateway, ring, and switch requirements before software scope and cybersecurity controls are frozen.

Protocol · Ports · Segmentation

Turn an I/O schedule into a reviewable control architecture

Include signal counts, cycle-time expectations, network nodes, ambient temperature, panel rating, available DIN rail space, software baseline, and any installed-base constraints. We return questions and compatibility points in a form purchasing and engineering can review together.

  • Series and firmware assumptions recorded
  • Accessory and terminal requirements identified
  • Migration risks separated from new-build choices
