Product Description:
The SOT02-E1A-AS operator terminal is manufactured by Bosch Rexroth Indramat and belongs to the SOT Operator Panels series. Classified as a station operator terminal, it forms the human-machine interface in an automated line, allowing users to call up status messages, step through recipes, and issue start or jog commands without direct access to the main controller. Its construction as a station unit means it can be positioned away from the drive or PLC cabinet while still providing immediate interaction on the factory floor.
Its front face contains a 16-line display illuminated by a CCFL backlight. Each row accommodates 40 characters, and the viewing window measures 4.875 x 2.75 in, giving space for clear text diagnostics. Contrast is user-adjustable so readability can be set for different lighting conditions. A standard membrane keyboard shares the panel with dedicated control inputs for Mode Select, Jog, and Start/Stop/Resume, giving rapid access to common motion commands. The terminal exchanges data through a CLM serial port that supports RS-485 wiring runs up to 1000 m. Within that channel, transmission speed tops out at 19200 baud, letting the unit poll variables, acknowledge alarms, and refresh screen content without delay.
The electronics inside the station include 128 KB of battery-backed RAM, which stores active screens and variable tables created on a DOS-based PC with the ScreenManager development utility. Once compiled, projects are downloaded and executed locally, so the panel can keep presenting data even if the host PC is disconnected. The housing is intended for remote-mounted installation, allowing the faceplate to sit on a machine frame while the connecting cable routes back to the controller enclosure. This arrangement simplifies retrofit work when an additional operator point is required.
