Description
Application Scenarios
Imagine a system integrator retrofitting a 1990s-vintage B&R 2003 cabinet on a bottling line: the original 7CP430 has run out of memory for the expanded recipe-handling logic, and the line needs more local I/O than 64 digital points. Swapping the controller for a 7CP474.60-1 instantly unlocks 512 KB of FlashPROM for the larger program, four physical slots for screw-in I/O modules, and a maximum I/O envelope of 208 digital or 80 analog points—all without rewiring the 24 VDC cabinet bus or re-architecting the CAN network. In a typical distributed control setup, the 7CP474.60-1 acts as the intelligent drop head, talking to upstream 7EX-series remote I/O bus controllers over CAN while running the local control logic autonomously, so a temporary network interruption never stalls the machine.

Technical Principles and Innovative Values
- Innovation Point 1 – Double-width 2003 footprint with 4 screw-in slots. Unlike the single-slot 7CP430/7CP470, the 7CP474.60-1 occupies two rack positions but delivers four local I/O slots, letting a single controller host a full mix of digital, analog, and specialty modules right next to the CPU.
- Innovation Point 2 – Electrically isolated, network-capable CAN. The integrated CAN interface on the 7CP474.60-1 is galvanically isolated and network-ready, allowing multiple CPUs and 7EX remote-I/O controllers to coexist on one bus without ground-loop noise—a critical feature on large distributed systems.
- Innovation Point 3 – Balanced memory architecture. With 100 KB SRAM for fast variable access and 512 KB FlashPROM for program and recipe storage, the 7CP474.60-1 hits the sweet spot for mid-complexity automation tasks without the cost premium of the 750 KB / 1.5 MB 7CP476 tier.
- Innovation Point 4 – Automation Studio programmability. The 7CP474.60-1 is fully supported by B&R Automation Studio (including the V4.0 HW Upgrade package released 19-Apr-2016), giving engineers a single development environment across the entire B&R CPU family and protecting the customer’s software investment.
- Innovation Point 5 – Industrial-grade certifications. CE, UKCA and cULus listings mean the 7CP474.60-1 can be deployed in control cabinets worldwide without additional compliance engineering—a hidden but significant cost saver for global machine builders.
