PLCs in Experiment Control Systems

• PLCs are well established in infrastructure
  systems
• low prices induced by mass market
• robustness
• long term availability and support from
  manufacturer
• Increasingly being used in experiment control
  systems
• Powerful development tools
• Strong communication capabilities decentral
  peripherie (ET200S,..), dedicated CPUs for
  subtasks
• Real time features
• IEC1131 Just a standardisation framework
• World market leader Siemens
• gt ZEL uses almost exclusively Siemens equipment
