Product Description:

The 3CP260.60-1 is a central processing unit produced by B & R Automation for the System 2005 Controllers series. Acting as the control core in an automated cell, it executes user programs, coordinates I/O, and maintains deterministic timing so that conveyors, actuators, and sensors follow defined sequences on the factory floor. By combining fixed onboard memory with plug-in storage options and a service serial port, the module supports mid-range machine tools, packaging lines, and process skids that demand cycle-accurate operation.

Internal data handling is organized around two program caches of 2 × 256 bytes that stage critical instructions before they reach the main DRAM bank of 4 MB. Application code is retained in a 512 KB FlashPROM area, while execution is paced by an instruction cycle time of 0.2 µs; this timing shows how quickly ladder steps or structured text statements can toggle outputs. The CPU carrier offers 2 interface module slots and a main rack geometry of 3 + 4 positions, but it does not support an expansion rack, so all fieldbus, power supply, and safety cards must remain local. This fixed architecture helps keep signal propagation predictable.

Removable storage and diagnostics are handled through a single PCMCIA slot. The permitted card height is 3 mm, and the slot accepts a Flash card with 16 MB of nonvolatile capacity for recipe sets together with equal battery-backed SRAM capacity for high-speed data logging. Asynchronous service laptops connect through the RS-232 port, which lacks galvanic isolation yet reaches a throughput of 64 kBaud. Time stamping of events is driven by a real-time clock that resolves to 1 s. An onboard SRAM pool of 850 KB safeguards retentive machine variables across power cycles.
