Helmholz 700‑600‑CAN01

Technical Specifications

• Power Supply: 24 V DC
• Baud Rate: 5 kbit/s ~ 1 Mbit/s configurable
• Protocol: CAN 2.0A, CAN 2.0B, CANopen
• Operating Temperature: -20 °C ~ +70 °C
• Protection Class: IP20
• Mounting: S7‑300 central rack or expansion rack slot Function Features
• Supports CAN‑open master and slave operation modes
• DIP‑switch configuration for station address and baud rate
• Built‑in CAN‑bus terminating resistor with on‑off switch
• Diagnostic LED indicators for bus status, error and activity
• Data mapping between CAN process objects and PLC process image area
• Supports SAE J1939 protocol handling blocks Application Scenarios: Factory automation production lines, material handling systems, packaging machinery, drive system CAN‑open network integration, retrofitting CAN‑bus devices to Siemens S7‑300 control systems. Performance Parameters: Real‑time telegram processing; error frame detection and bus‑error counter; galvanic isolation between PLC backplane and CAN bus side. Material Composition: Reinforced industrial‑grade plastic housing; gold‑plated backplane connector; isolated CAN transceiver chip. Structural Characteristics: Standard S7‑300 module width; front‑side DIP‑switch and status LED window; internal backplane bus connector; external CAN terminal screw terminals. Working Principle: Exchanges data with S7‑300 CPU via rack backplane; encapsulates / decapsulates data into CAN‑bus telegrams; executes CAN‑open object dictionary processing; transfers process data between PLC memory and CAN‑bus field devices. Installation Requirements: Insert into S7‑300 rack slot; lock module latch; wire CAN‑bus lines according to CAN‑bus wiring specification; enable internal terminator at physical bus end‑node. Usage Notes: Keep CAN‑bus cable separated from high‑power power cables; verify baud‑rate consistency across all CAN‑bus nodes; do not remove / insert module under powered‑on rack condition.
