LAUER PCS600 Operator Panel PG 600.105.2

Product Overview

The LAUER PCS600 (version PG 600.105.2) is a compact graphic operator panel designed for small to medium industrial machines. It provides a clear, high‑contrast graphic display and a tactile keypad, enabling operators to monitor processes, adjust parameters, and handle alarms efficiently. The panel is cost‑effective yet feature‑rich, making it ideal for packaging, textile, and woodworking machinery.

Display and Graphics

The panel is equipped with a 5.7‑inch STN graphic LCD with a resolution of 320 x 240 pixels and a white LED backlight. The display supports text, bitmap graphics, and simple animations – allowing the creation of bar graphs, trend indicators, and mimic diagrams. The contrast is software‑adjustable, and the screen is protected by a hard‑coated polyester overlay that resists scratches and chemicals.

Keypad and User Input

The front panel includes a 20‑key membrane keypad with 10 numeric keys (0‑9), decimal point, sign, and 8 programmable function keys (F1‑F8) with LED status indicators. The keys are tactile, backlit, and rated for 500,000 actuations. The overlay is IP65 rated for protection against dust and water spray.

Communication and Connectivity

The panel provides two serial ports: Port 1 (RS‑232, 9‑pin D‑sub) and Port 2 (RS‑485, screw terminal block). Baud rates from 1200 to 115200 bps are supported, with parity and data format configurable. Protocols supported: Modbus RTU (master and slave), LAUER PCS protocol, and ASCII transparent. The RS‑485 port allows multi‑drop networks with up to 31 devices.

Memory and Data Management

• Flash Memory: 256 KB – stores up to 200 user‑defined screens.

• SRAM: 128 KB for variables and runtime data.

• Variables: 1000 internal registers (bit, byte, word, double word, float).

• Alarms: 100 alarm messages with priority levels and a 50‑event history log (battery‑backed).

• Recipes: 30 recipe records, each with up to 50 parameters.

• Languages: Up to 5 languages, switchable via key or external variable.

Electrical Specifications

• Supply Voltage: 24 V DC ±15 % (19‑33 V DC)

• Power Consumption: 250 mA typical (approx. 6 W)

• Isolation: 500 V between power and serial ports

• Protection: Reverse polarity and transient suppression

Mechanical and Environmental Data

• Housing: ABS/PC blend, UL94 V‑0, front IP65, rear IP20

• Mounting: Panel‑mount with spring clips (cut‑out 166 mm x 126 mm)

• Dimensions: 190 mm x 150 mm x 45 mm (W x H x D)

• Weight: 0.6 kg

• Operating Temperature: 0 °C to +50 °C

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

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

Configuration and Software

The PCS600 is programmed using the LAUER PCS‑Config software (version 3.0 or higher). The software provides a drag‑and‑drop screen editor with a library of standard objects (numeric input, selection lists, bar graphs, and text fields). It also includes a tag database, alarm editor, recipe manager, and communication wizard. The project is downloaded via the RS‑232 port using a null‑modem cable. The software offers online monitoring, allowing the user to view and modify variables in real time while the panel is running.

Installation and Commissioning

Prepare the panel cut‑out, insert the unit from the front, and secure with the spring clips – ensure the gasket is evenly compressed. Connect the 24 V power supply (two‑pin terminal block) with 0.75‑1.0 mm² wires. For RS‑232, use a shielded cable to the 9‑pin D‑sub (pin 2: RX, pin 3: TX, pin 5: GND). For RS‑485, connect A, B, and GND to the screw terminals – enable the internal termination if at the end of the bus. Apply power – the panel will show a startup message. Download the application using the configuration software. After download, restart the panel – the new screens will be active. Test all keys and communication with the PLC. Adjust contrast via software if necessary.

Maintenance and Troubleshooting

Clean the front overlay with a soft, damp cloth – avoid solvents. The LED backlight has a typical lifetime of 50,000 hours; dimming indicates end‑of‑life, requiring unit replacement. The internal battery (CR2032) for the alarm history and RTC should be replaced every 5 years – accessible through the rear cover. Common faults:

• No communication: Check cable wiring, baud rate, and protocol settings.

• Display flicker: Check power supply for ripple; should be < 100 mV.

• Key not responding: Clean around the key edges; if persistent, replace keypad.

• Application corrupted: Reload the project from the backup file.

For hardware failures beyond the battery and keypad, return the unit to LAUER service.

Compatibility and Ordering

The PCS600 PG 600.105.2 is compatible with all LAUER LCA and PCS controllers, as well as with PLCs supporting Modbus RTU. Variants include different backlight colours (red, white) and extended temperature range. When ordering, specify the exact part number PG 600.105.2 and any custom key legends.
