Hello Friends,
My customer uses Matrikon OPC DA server for collecting data from several GPRS devices. Data is stored in MySQL database. But sometimes I need to send read request on demand(to refresh data) what is not possible to do using database. Has anybody tried to connect directly Codesys to any OPC server?
Thanks for your help,
