Product Description:

The 0GH-CP260 CPU module is produced by B&R Automation for the 0GH PLC Modules series. The unit functions as the central processing component in a modular programmable logic controller, coordinating sequencing, arithmetic, and serial communication tasks for automated machinery and plant cells. By combining onboard memory resources with field-ready interfaces, the module provides deterministic control and data exchange between I/O carriers, HMI terminals, and supervisory networks. Its design supports compact system layouts where space, removable media, and low-latency program execution are required.

The processing core is a 2005 CPU, delivering deterministic ladder and structured text execution cycles. Working memory is divided into 4 MB of DRAM for dynamic code execution, 512 kB of FlashPROM for stored system data, and 850 kB of battery-backed SRAM that retains critical variables during power loss. Program and diagnostic data can be transferred through the onboard RS-232 service port, and this interface supports transmission speeds up to 64 kBaud, allowing fast downloads without external converters. This memory layout supports multitasking, recipe storage, and high-frequency interrupt routines without overrunning the internal cache of 2 x 256 bytes.

Removable media options expand the base capacity. One PCMCIA slot accepts linear Flash or SRAM cards up to 16 MB each, and the card must have a maximum height of 3 mm and comply with the JEIDA V4.0 or PCMCIA 2.0 standard. Two additional insert slots accommodate proprietary option boards for fieldbus or analog I/O adaptation. Real-time data logging remains time-stamped by an integrated clock that updates with a resolution of 1 s. For serial wiring, the RS-232 channel terminates on a 9-pin D-Sub plug, which simplifies cable changes inside control enclosures while supporting a reach of 15 m at 19,200 baud.
