HMI or SCADA

• HMI, Human Machine Interfaces enable the
  interaction between a human and machine eg.
  control panels.
• SCADA Supervisory Control and Data Acquisition
  The level of applications that monitor and
  control devices such as programmable controllers.
  These systems are usually PC or workstation
  based.

• Many HMI/SCADA vendors Company name Product name
• GE/Intellution iFix, Cimplicity, Proficy
• Rockwell Software RSView32
• Siemens WinCC
• Schneider MonitorPro
• Arc Informatique PCVue32
• Europ Supervision Panorama
• Axeda WizCon
• USData FactoryLink
• Wonderware InTouch
• National Instruments LookOut
• Axica Adroit

• The HMI/SCADA issue
• Find a compatible driver network to grab datas
  from the devices/PLCs.
• In case of large PLC architecture, find a
  Powerful Communication solution to avoid
  bottleneck
• Dependent on the PLC choice (Siemens, Rockwell,
  Schneider, GE, ) from the end-user
• Dependent on the network choice from the end-user
  (Ethernet, Profibus, DeviceNet, Serial)
• Dependent on the protocol choice of the end-user
  (eg. Modbus, SNP-X, PCCC, Uni-Telway, Fipway, )

  specifications supplied by a vendor to facilitate
  exchanges of data with third party software or
  hardware.
• 1- Under Windows, they are called DLL (Dynamic
  Link Library).
• 2- For Non-Windows (Linux, VX-Works, QNX, ),
  they are called Static Library.

Key words OPC
10
Data Servers (next) OPC, OLE for Process Control

• What is OPC
• OPC (originally OLE for Process Control) is an
  industry standard created with the collaboration
  of a number a leading worldwide automation and
  hardware software suppliers working in
  cooperation with Microsoft. The standard defines
  method for exchanging realtime automation data
  among PC-based clients using Microsoft operating
  systems. The organization that manages this
  standard is the OPC Foundation.
• OPC (OLE for Process Control) is a defined set of
  interfaces, based on OLE/COM and DCOM technology,
  for truly open software application
  interoperability between automation/control
  applications, field systems/devices and
  business/office applications.
• OPC is based on COM (Microsoft Component Object
  Model), a software architecture that allows one
  program to use the interface of another program
  to get information from it (as long as it is
  programmed as a COM component).
• DCOM (Distributed Component Object Model) is the
  network-aware version of COM technology.

OPC Client(HMI/SCADA, )
OPC Server
Industrial network
11
Data Servers (next 2) OPC and Software vendors

• OPC offers interoperability so
• As OPC offers interoperability between Software
  application and field/systems devices, most
  popular SCADA/HMI on the market are  OPC Client
  Compliant . (RSView32, WinCC, MonitorPro,
  PCVue32, Panorama, Adroit, wizcon, )
• In theory, any OPC client is able to connect to
  any OPC servers from the market. With more or
  less features.
