Product Description:

The 4D1042.00-K02 text operator panel is built by B & R Automation and belongs to the 4D PanelWare Panels series. Designed for machine-level interaction, this unit combines a character display and keypad so technicians can enter parameters, view process results, and trigger predefined functions directly at the equipment. In an automation cell it acts as the local human–machine interface, forwarding values to the controller and presenting feedback without requiring a full graphical terminal. Its compact construction suits panel-mount installations.

Its display presents data in a matrix of 4 x 20 characters, giving four lines of twenty alphanumeric symbols for menus, status text, or variable values. Input is handled through 16 dedicated function keys that can be mapped to start sequences, acknowledge alarms, or navigate pages, while a block of 10 numeric keys supports direct value entry. The front panel and display remain active during power interruptions because the internal power source uses a Lithium cell; only 1 battery is required, cutting maintenance trips and shelf space. By integrating this energy reserve the panel can keep clock data and retain last-shown messages between machine cycles. The manufacturer name B & R Automation on the bezel signifies compatibility with the firm’s PLC families and programming tools.

For archival or label printing the panel offers a serial printer port that follows the RS232 signaling standard, so legacy ticket, dot-matrix, or slip printers can be linked with a simple null-modem cable. When a print command is issued the unit transmits records in ASCII coding, each line padded to a fixed width of 80 columns; this ensures the receiving device produces a uniform line length that matches common stationary formats. Together these communication features allow operators to capture batch totals, alarm histories, and parameter lists without relying on the central control network.
