Ag Automation Posted January 15, 2014 Report Share Posted January 15, 2014 We have used Pcom to communicate to the data tables in the vision series. How do you recommend communicating to the data tables with the unistream? I would like to connect to a database that I built in Ms access. What would be recommended method? 1 Link to comment Share on other sites More sharing options...
Ofir Posted March 31, 2014 Report Share Posted March 31, 2014 Hi, Currently there is no direct way to access the data tables memory. You can built your own protocol to read write data to data tables. You can create commands and messages with variables using message composer in UniLogic and then using TCP TX and TCP RX ladder elements you send and receive data. For example you can send the string Read_Row1 from your PC applicaiton and then when the UniStream recieves this message, it will activate read row for the requested index number and for specific tags and then will send the data back to the PC application.
