Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The BECKHOFF C9900-E527 is a dedicated push-button extension designed for integration with industrial operator interfaces. It is built specifically to expand the physical control options of BECKHOFF CP6xxx and CP7xxx Control Panels and Panel PCs equipped with 19-inch displays that do not feature integrated keyboards, including CP6x03-00xx and CP7x03-00xx configurations. This accessory is currently in its service phase, making it highly relevant for the maintenance and modernization of existing control architectures.
For installation on the right side of the panel, the BECKHOFF C9900-E527 features 20 Siemens Signum square (30 x 30 mm) push-buttons, each equipped with an integrated signal lamp to provide immediate operational feedback. In addition, a dedicated Siemens Signum emergency stop key is incorporated directly into the panel layout to ensure a reliable safety interface. The push-button caps are designed with clear insertable labels, enabling customized operator marking for clear system navigation.
Engineered with dual-channel wiring flexibility, the push-buttons transmit their states to the controller via USB with a standard normally-open (NO) contact. For integration with hardware-based interlocks or safety systems, every push-button includes a second, independent normally-open contact that can be directly hardwired to external automation systems using a terminal row. All signal indicators and lamps are driven exclusively via the USB connection.
