Boa Noite,

Configurei o OPC Serve, mas as variáveis do Tipo Word não estão conseguindo comandar os atuadores. Para a Variável D0 atribui o valor 7, mas o display não reconhece conforme figura.

Can you check if Factory I/O is in run mode? In edit mode the digital display won’t show the value of the OPC DA item.
