LAUER PCS095 Complete Controller Display

Product Introduction

The LAUER PCS095 is a complete controller display unit that integrates a graphic operator panel with a powerful control logic core, providing an all‑in‑one solution for machine control and visualization. This panel is designed for medium‑complexity automation tasks where space is limited but a graphical user interface is required. It combines a 5.7‑inch STN graphic display with a membrane keypad, serial communication ports, and a built‑in PLC‑like logic engine, enabling standalone operation without an external controller.

Display and User Interface

The PCS095 features a 5.7‑inch (diagonal) graphic LCD with a resolution of 320 x 240 pixels and a bright white LED backlight (adjustable intensity). The screen supports both text and bitmap graphics, allowing the creation of custom screens with bar graphs, trend charts, and simple animations. A resistive touchscreen is optional (model variant). The front panel includes 24 tactile keys: 10 numeric keys (0‑9), decimal point, sign, and 12 programmable function keys (F1‑F12) with LEDs for status indication. The overlay is IP65 rated for water and dust protection.

Control Logic and Memory

At the heart of the PCS095 is a 16‑bit microcontroller (Infineon C167) with 512 KB of flash memory for user programs and 128 KB of SRAM for runtime data. The logic engine supports a subset of IEC 61131‑3 languages (ladder diagram and function block diagram) via the LAUER LogicBuilder software. The unit can execute up to 1000 logic instructions per millisecond, handling typical machine sequences, interlocks, and timer/counter functions. The application program can be stored in the internal flash or on an external memory card (optional).

Communication Interfaces

• Serial Port 1: RS‑232 (9‑pin D‑sub) – for programming and communication with external devices.

• Serial Port 2: RS‑422/485 (5‑pin screw terminal) – for multi‑drop networks.

• Protocol Support: Modbus RTU (master/slave), LAUER LCA protocol, and ASCII.

• Ethernet (optional): 10/100 Base‑T via plug‑in module, supporting Modbus TCP and OPC UA.

• Expansion Slot: For fieldbus modules (Profibus DP, CANopen, DeviceNet).

Electrical and Mechanical Specifications

• Power Supply: 24 V DC ±15 %, 500 mA max

• Storage Temperature: –20 °C to 70 °C

• Humidity: 10 – 90 % RH (non‑condensing)

• Housing: ABS plastic, flame‑retardant (UL94 V‑0)

• Mounting: Panel‑mount (cut‑out 166 mm x 126 mm) with screw clamps

• Dimensions: 190 mm x 150 mm x 55 mm (W x H x D)

• Weight: 0.9 kg

Configuration and Programming

The PCS095 is configured using two software tools: PCS‑Config for screen design and LogicBuilder for control logic. Both tools run under Windows and communicate with the panel via the RS‑232 port. The screen editor offers a library of pre‑defined objects (numeric input, selection lists, gauges, etc.) and supports multi‑language text (up to 5 languages). The logic editor allows the user to write ladder logic and define variables that are shared with the screen application. After development, the entire project (screens + logic) is compiled and downloaded to the panel in a single operation. The software includes an online monitor for debugging both the logic and the screen variables.

Installation and Commissioning

Mount the panel in the control cabinet using the provided screws and ensure the sealing gasket is correctly placed. Connect the 24 V power supply (two‑pin terminal) and the communication cables. For first‑time use, power on the panel – it will boot and display a default screen. Connect the programming cable to the RS‑232 port (use a null‑modem cable). Launch the configuration software and establish communication (auto‑detect baud rate). Download the project; the panel will restart and run the new application. If the panel does not communicate, check the COM port settings and cable wiring.

Maintenance and Troubleshooting

The PCS095 is designed for long‑term reliability. Periodic cleaning of the front screen with a soft cloth is recommended. The internal battery (CR2032) for the real‑time clock and data retention should be replaced every 5 years – accessible through the rear cover. If the panel exhibits erratic behavior, check the power supply for ripple (should be < 100 mV). Common errors: “No Logic” – the application may be missing or corrupted; reload the project. “Screen Freeze” – press the reset button (recessed on rear) to reboot. If the display backlight fails, the entire unit must be replaced as the backlight is not field‑replaceable.

Variants and Ordering

The PCS095 is available in several variants: with or without touchscreen, with different keypad legends, and with optional Ethernet or fieldbus interfaces. The standard part number for the complete controller display without touch is PCS095‑C. When ordering, specify the desired communication options and any custom screen pre‑loading.
