Introduction
The WebCAN Substation Control and Monitoring System can easily be setup in a harsh substation environment simplifying module mounting, connecting of all field I/O points and configuring all system parameters using the user friendly WebCAN Designer configuration application.
This hardware user manual explains all steps and processes involved setting up and commissioning the hardware for the WebCAN Substation Control and Monitoring system.
This document covers the following sections:
- Description of all essential WebCAN system components
- Installation guidelines for system installation
- Basis configuration of the WebCAN Substation Control and Monitoring System
- System trouble shooting
General Description
Stand-alone Single Node System:
For simple applications without redundant requirements for hardware and software, a stand-alone single node system is a sufficient system configuration. It comprises of a single CFE module with a centralized database system. A maximum of 15 field I/O modules can be connected to the CFE front-end. All software applications are non-redundant.
Maximum System Configuration:
- 1x Communications Front-end Processor Module
- 8 x Serial communications ports (max)
- 2 x Ethernet 10/100 T Base Ports
- 1 x GPS Time Synchronization Unit
- 1 x Power Supply Unit ( with 1 redundant unit as ption)
- 15 x mixed Field Input/Output Modules distributable up to 50 meters
Local Multi-Node System:
Applications requiring a high I/O point count and redundancy for hardware components and software applications are arranged in a local multi-node system comprising of a maximum of four CFE modules in one rack equipped with stand-alone or redundant software applications.
Maximum System Configuration:
- 4 x Communications Front-end Processor Module
- 32 x Serial communications ports (max)
- 8 x Ethernet 10/100 T Base Ports (4 are used for networking the front-end processor modules)
- 1 x GPS Time Synchronization Unit and one optional redundant modules as back-up
- 1 x Power Supply Unit with a second backup unit as option
- 60 x mixed Field Input/Output Modules distributable up to 50 meters managed by four communications front-end processor modules
Wide Area Multi-Node System:
A wide area multi-node system utilizes a redundant fibre optic Ethernet ring as communications backbone linking various nodes of the system. All software applications including IEC 61131 are able to exchange and process data via the Ethernet network. The network can also be configured as an IEC 61850 system.
Maximum System Configuration:
- 64 x Communications Front-end Processor Module linked via redundant Ethernet fibre optic ring
- 8 x Serial communications ports (max) at each network node
- 4 x Ethernet 10/100 T Base Ports at each node (2 are used for networking the front-end processor modules via fibre optic ring)
- 1 x GPS Time Synchronization Unit synchronizing all CFE modules or 1 x GPS Synchronization Unit at each network node
- 1 x Power Supply Unit at each network node
- 6 x mixed Field Input/Output Modules distributable up to 50 meters managed by one communications front-end processor modules
All front-end modules are installed in the 4U design, RAK-10 rack. This rack is a 2-compartment rack catering for all active modules in its front compartment and all cable and field termination passive modules are in the rear compartment. A total of 15 front modules slots and 17 rear module slots are provided. All wiring and optical cable are in the rear allowing for uncluttered access to all active modules from the front.
