Lauer PCS 810 E Interface Assembly

The Lauer PCS 810 E Interface Assembly is a specialized connection unit designed to bridge Lauer operator panels and control systems with Siemens-compatible automation networks, specifically the 6ES5 series (model 491 0LB11). This assembly provides a standardized interface for signal exchange, ensuring reliable communication between different generations of equipment. Its compact form factor and plug-and-play design simplify integration in both new and retrofit projects.

Functional Features

The assembly acts as a physical and electrical adapter, converting the pinout and signal levels of the Lauer panel to match the Siemens 6ES5 bus system. It includes built-in termination resistors that can be enabled via DIP switches, allowing proper bus termination in daisy-chain networks. The unit is designed to minimize signal distortion and provides galvanic isolation to protect connected devices from ground loops and voltage spikes.

No software configuration is required; the assembly is purely hardware-based. It supports half-duplex communication and is compatible with standard Siemens protocols such as 3964R. The assembly also includes a diagnostic LED that flashes to indicate data transmission activity.

Installation Guidelines

Mount the assembly on a DIN rail or using screws. Connect the panel cable to the D-sub connector, and wire the field terminals to the Siemens I/O module (pins 2, 3, and 5). Enable termination resistors if this unit is at the end of the bus. Ensure the power is derived from the connected system; no external power supply is required. Ground the shield of the cable to the earth terminal.

Verify the wiring against the pinout diagram provided in the documentation. Test the communication using a diagnostic tool or by monitoring the LED activity.

Operating Conditions

This assembly is intended for indoor use in control cabinets, with ambient temperatures from 0 to 50 °C. It can tolerate vibration up to 0.3 g and shock up to 5 g. It is not rated for outdoor or harsh chemical environments.

Applications

Ideal for connecting Lauer HMIs to Siemens S5 PLC systems, retrofitting older machines with modern operator interfaces, and integrating Lauer panels into existing Siemens-based automation networks.
