This information is then used bythe respective functions in ACT (for example protection, measurement ormonitoring).The SMAI function is used within PCM600 in direct relation with the Signal Matrixtool or the Application Configuration tool.The SMAI function blocks for the 650 series of products are possibleto set for two cycle times either 5 or 20ms. The function blocksconnected to a SMAI function block shall always have the same cycletime as the SMAI block.17.9.2 IdentificationFunction description IEC 61850identificationIEC 60617identificationANSI/IEEE C37.2device numberSignal matrix for analog inputs SMAI_20_x - -Section 17 1MRK 502 048-UEN ABasic IED functions638Technical manual
