Product Description:

The VCP20.1BUN-256PB-NN-PW is a panel-mounted operator terminal produced by Bosch Rexroth Indramat and placed within the VCP IndraControl Terminals series. In an automation cell, it serves as the local human-machine interface that collects operator commands, shows process data, and forwards instructions to drives and PLC nodes over its fieldbus link. The unit combines a graphic LCD, onboard processing, and field wiring points into a compact front plate that fits directly into machine enclosures, giving operators a clear view of machine status without opening the control cabinet.

Its 8-bit Z84 CPU runs at 10 MHz, a frequency sufficient for menu navigation, alarm handling, and simple logic preprocessing before data is sent to the controller network. Program code and recipes are retained in 256 kByte Flash application memory, while runtime variables reside in 128 kByte Static CMOS-RAM that is battery-backed to avoid data loss during power cycling. Screen content is rendered at 240 × 128 pixels across a transmissive display area measuring 131 × 72 mm, allowing clear depiction of bitmaps, trend curves, and multilingual text. Data exchange with higher-level systems occurs through a PROFIBUS-DP interface, enabling deterministic communication with drives, I/O modules, and supervisory PLCs.

As a machine-front component, the terminal must withstand shop-floor conditions. The aluminum bezel gives the front face an IP54 rating, protecting the keypad and display from dust ingress and water splashes, while the rear remains at IP20 because it is housed inside the cabinet. Illumination is provided by a cold-cathode backlight rated for 10,000 hours, and the LCD has a service life of 50,000 hours. The unit draws logic power from a single 24 V DC supply, simplifying wiring inside multi-axis drive racks and allowing the screen and electronics to remain operational during battery-buffered emergency-stop sequences.
