nhanleduy Posted July 22, 2012 Share Posted July 22, 2012 Hi Admin, My Project is communicate betwwen DAQfactory and OPC server (KEPWARE) but when settting a channel as Analog out put, the channel just only write out value. He do not update his channel value if OPC Server change data value. The Stranger is, If I firstly set channel as Synchronous Read then change to Analog Out Put ->He working ok but not working again when i exit and open a gain progam. I also doing the same way with other HMI software the channel update it self if other action change data in Kepware. I really spend so much time to fix it but nothing better, Link to comment Share on other sites More sharing options...
AzeoTech Posted July 23, 2012 Share Posted July 23, 2012 You have to create two channels, one for input and one for output. Try and use Async read instead of sync. Link to comment Share on other sites More sharing options...
