2. Additional Details
2.1 About PROFINET Technology
Flexible Network Topology:
100% Ethernet-compatible according to IEEE standards. It adapts to existing plant conditions with flexible line, ring, and star topologies and supports both copper and fiber-optic cable solutions.
Integrated Diagnostics:
Built-in intelligent diagnostic concepts for field devices and networks. Acyclic diagnostic data transmission provides important information regarding the status of devices and networks, including network topology displays.
High Availability:
Automatically reacting redundancy solutions are integrated.
Scalable Real Time Communication:
Offers a common cable solution for all applications—from simple control tasks to highly demanding motion control applications. For high-precision closed-loop control tasks, deterministic and isochronous transmission of time-critical process data with jitter of less than 1 μs is achievable.
Expanded System Structures:
In addition to the conventional automation structure (controller and its field devices), hierarchical systems with intelligent field devices and shared usage by multiple controllers can be implemented.
Communication Standards:
Uses established IT protocols such as TCP, UDP, and IP. XML is used as the description language for device profiles (GSDML files).
Two Usage Options:
PROFINET IO: Similar to PROFIBUS DP as a distributed I/O system, where IO controllers (e.g., PLCs) run the automation program, IO devices (e.g., absolute encoders) are configured as field devices, and IO supervisors (e.g., programming devices) are used for commissioning and diagnostics.
PROFINET CBA: A modular component-based system designed for larger-scale applications.
2.2 Engineering Configuration and Data Exchange
Configuration:
Engineering is similar to PROFIBUS. The Ethernet networks (field buses) are assigned to control systems during configuration using the GSDML file of the IO device.
Data Exchange:
After engineering, the installer loads the expansion data into the IO controller (PLC), which then exchanges process data cyclically with the IO device via its IP address. Parameter data may also be exchanged acyclically during device configuration or through PLC programming blocks.
2.3 Ordering and Selection Guidelines
Selection Steps:
Brand Comparison: If you have used encoders from other brands, provide the brand and model information so that our engineers can recommend a high cost-performance equivalent.
Encoder Type: Choose the type you need (Incremental encoder, Absolute encoder, Draw Wire Sensors, or Manual Pulse Generator).
Output Format/Interface: For incremental encoders, select output formats (NPN/PNP/Line Driver/Push-Pull) or interfaces (e.g., Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP).
Resolution: Choose the resolution (e.g., up to 50,000 ppr for Gertech incremental encoders, up to 29 bits for Gertech Absolute Encoders).
Dimensions: Select the housing diameter and shaft diameter.
Minimum Order Quantity and Production Capacity:
MOQ: 20 pieces (smaller quantities are possible but may incur higher freight costs).
Production capacity: Approximately 5000 pieces per week, with a second production line being built.
Warranty and Support:
1-year warranty and lifetime technical support.
Agencies benefit from special pricing, market protection, and full support.
