Product Specifications

Technical details and manufacturing context for Communication Processor

Definition
The Communication Processor is a critical hardware component embedded in the Teach Pendant Interface, responsible for encoding, decoding, routing, and error-checking all communication signals. It facilitates real-time, bidirectional data transfer between the operator's handheld pendant and the main robot controller or PLC, ensuring reliable transmission of commands, status updates, and safety signals. The processor operates by receiving digital or analog signals from the pendant's input devices (buttons, joysticks, touchscreen). It converts these user inputs into standardized industrial communication protocol packets (e.g., Ethernet/IP, PROFINET, DeviceNet). It then transmits these packets via the interface's physical layer (cable/wireless). Simultaneously, it receives status and feedback data from the controller, decodes the packets, and prepares the information for display or indication on the pendant. It manages timing, prioritization, and error correction to maintain communication integrity. Typical specifications include a supply voltage of 24 V DC ±10% (per IEC 61131-2), power consumption of 5–15 W, operating temperature range of -20 to 60 °C (with derating above 60 °C), storage temperature range of -40 to 85 °C, relative humidity of 10–95% non-condensing, ingress protection rating of IP54–IP65, one or two communication ports supporting Ethernet, PROFINET, or EtherCAT, data rates of 10–100 Mbit/s, support for 2–5 protocols (common: PROFINET, EtherNet/IP, Modbus TCP), processor clock speed of 400–800 MHz, memory capacity of 128–512 MB (flash and RAM combined), weight of 0.2–0.5 kg, and dimensions of 100–150 x 60–100 x 20–40 mm. These values are reference ranges and must be verified for the specific model and application. The processor is constructed with semiconductor (silicon), PCB, solder, and plastic/epoxy encapsulation. It is designed for use in machinery and equipment manufacturing, specifically as a component in teach pendant interfaces. Always confirm model-specific values and standards with the legal manufacturer or supplier.
Working Principle
The processor receives input signals from the pendant's buttons, joysticks, and touchscreen. It converts these analog or digital inputs into standardized industrial protocol packets (e.g., Ethernet/IP, PROFINET, DeviceNet). These packets are transmitted through the physical layer (cable or wireless) to the controller. Simultaneously, it receives status and feedback data from the controller, decodes the packets, and prepares the information for display on the pendant. It manages timing, prioritization, and error correction to maintain communication integrity.
