10. CERN PLC Workshop – ITER IO 4-5 December 2014 Conclusions from test platform 10 [11] 1.Management of complex situation Failures are isolated from the rest of the system; the problems of one partner will not affect the performance of the whole system. 2.No advantage of hardwired connections (from I/O to I/O) compared to network. No advantage in terms of performance, maintainability, cubicle space, integration and scalability. 3.While the CPU can manage the configuration within one cycle interrupt, the response time of the central functions is almost independent from the number of partners and the communication functions. 4.The restoration of the functionality after a master switch over requires 700ms as a minimum, and with four communication instances per PIS (2 F_SEND/2F_RCV) the system can assure restoration times below 1 second. 5.The performance of a central function is below 350ms and local functions based in digital inputs have a performance below 150 ms. 6.The use of analogue inputs can double the time required for a digital input, below 225 ms
