  2. Saia® PCD systemdescription • Saia® PCDs combine PLC functionality with innovative Web+IT technology. The conventional automation pyramid is becoming an open, transparent structure System catalogue | Chapter A1 | Basic Properties

  3. Lifecycle of Saia® PCDs • Compatibility and portability guaranteed for all device types across generations • Standards • Industrial quality in design and production (IEC EN 61131-2) • CE and UL standard • Ship approbation System catalogue | Chapter A1 | Basic Properties

  4. Saia®COSinusoperatingsystem • Saia®COSinus operating system – The key for the long lifecycle guarantee • COS stands for „Control Operating System“ • COSinusstands for the trigonometric relations in triangles • The angle or Saia® COSinus always fits, no matter how much the hardware or application changes System catalogue | Chapter A1 | Basic Properties

  5. Executionofuserprogram • The cycle time for the user program depends on • the length of the program • the additional load at the same time(communication, web functions) Cycle time without any further communication Cycle time with BACnet® communication Cycle time with BACnet® communication and interrupt (XOB) System catalogue | Chapter A1 | Basic Properties

  6. OpcodeandAutomationServer • The saia virtual machine compiles the opcode: • Saia® PG5 generates a platform-independent opcode • Saia®COSinus compiles the opcode with a perfect fitting to the hardware • Due to the perfect fit the code will run faster on the PCD • AutomationServer includes web technologies to exchange data with users • Web server • File system • FTP-Server • Email • SNMP • SNTP • DHCP • DNS System catalogue | Chapter A1 | Basic Properties

  7. Memory management • A Saia® PCD hasbasicallytwo different memoytypes • The user memory (RAM) ensures fast accessfortheprogramandissupportedwith a battery • The flash memory (ROM) permanentlysavesdata • Saia® PCDs aredevided in groupswithμSD cardand on board flash • In μSD devicesthe PG5 programissaved on theμSD cardandloaded on startupofthe Saia® PCD • In onboardflash devicestheprogramisloadedtotheuser memory andoptionallysaved on theonboardflash System catalogue | Chapter A1 | Basic Properties
