Getting rough with industrial wireless A Case Study Marc Lee Senior Tech Support / Trainer
Drivers of Industrial Wireless Deployment: Case Study Industrial Wireless Design Challenges Consideration
Drivers of Industrial Wireless Deployment: Mobility & increased efficiency: Remote access via laptops in the field (Commissioning) Replacement of wired field terminals Flexibility: Cranes in mining and steel companies Moving bridges in water/ waste water basins Moving transport & logistic solutions ( Fork lifters, AGV s) Robots in automotive applications Cost savings: Where cables are not possible or flexible or to expensive (Specific Safety zone s etc) To be competitive, by leveraging advanced technology
Benefits Particular in Process Automation Less need for local panels Fast commissioning Increased field operability / visibility Local advanced diagnostics direct access via wireless application. Future proof multipurpose Ethernet backbone with LAN and WLAN connections (VLAN and Multi-SSID for Video, Voice,..) Flexibility and cost savings: Operators can react in the filed and system is engineered for future expansions
Industrial network layer Wireless AP Enterprise Resource Planning Business domain Firewall Switch Control level PLC Field level TRANSMITTER SENSOR TRANSMITTER VALVE PENDENT BUTTONS
Design challenges End-to-end solution (from design to installation inclusive rugged laptops) Requirements on hardware with explosion certification (ATEX zone 2) & IEC 60079 system compliancy WLAN design bases on plot plans Real outdoor process environment (lots of metal interference & reflections) Network design Backbone with Redundant-Ring and WLAN Point-to-Point Links Harsh Environmental Conditions (lightning, high temperature, high humidity, salty air, )
Antennas and Accessories Omnidirectional Directional Cables, Pigtails Lightning Protection
WLAN Design 3D-CAD Model of the plant: Location of Access Points, Free line of sight,.. WLAN Simulation by RF-CAD modeling software: Coverage, bandwidth, interference,.. Frequency plan for whole system Defining LAN, interfaces, patch panels Firewall Rules and security aspects Detailed documentation of whole system: Overview Network Architecture Block Diagram List of material Cable List Function Design Specification
WLAN Design
WLAN Design (+) Mounting (the Access points, antenna s, Surge arrestors etc) Power plan for equipment (Non EX Ex zones) Grounding plan (for electrical and antenna s) ATEX zone 2, IEC 60079 system compliancy Customized lengths for antenna (RF) cables Outdoor EX housings and sun shelters Antenna at Critical Location Protection Distance > 100 cm Weather hardening of connectors etc. Grounding 16mm²
Specific solutions needed Lightning protection for exposed position External box with power supply and media converter Sun Shelter for power supply box Firmware adaptations for Access Points Engineering of Network Management System
WLAN Design (+) Services: Consulting, Engineering Project Management Site Survey, Training, Site Support,... Hardware: Access Points and accessories, Switches, Firewall, Media Converter, Power Supply, antennas, Sun shelter Ex outdoor housings cables,.. Firmware: Network Management Configuration of APs, firewalls, Switches etc., etc.
Wireless Network Management
Wind Farm Application WLAN use cases
WLAN use cases 100m 50m Leaky Cable
Conclusion Industrial network ask for: scalable, redundant LAN and WLAN Entire WLAN system for end-to-end solution with Ex certification Full Project Management and services Improved operational efficiency Mobile workers and maintenance Cost reduction due to WLAN
