Abstract
"PROCESSOS E APARELHO PARA OBTENçãO DE DADOS REPRESENTATIVOS DO DESEMPENHO OPERACIONAL DE UM DISPOSITIVO DE CONTROLE DE PROCESSO, SISTEMA DE CONTROLE PARA AVALIAçãO DA OPERAçãO DE UM DISPOSITIVO DE CONTROLE UTILIZADO PARA CONTROLAR UM PROCESSO, E, PROCESSO PARA AQUISIçãO DE DADOS". São obtidas amostras de dados (A - L) de um dispositivo de controle (10, 11, 12, 16, 17) durante a utilização para controle de um processo de material (13). Amostras selecionadas destas amostras são armazenadas representando resultados da operação do dispositivo através de partes de suas características, e as mesmas são seletivamente combinadas para obtenção de uma indicação das características do dispositivo inteiro. Amostras selecionadas destas amostras de dados são utilizadas para obtenção de informações relativas a parâmetros selecionados do dispositivo de controle com base nas características do dispositivo.
