Paulo Ferreira Posted January 21, 2011 Report Posted January 21, 2011 Is it possible to get some feedback or ACK of the data that is sent from Excel to the PLC. I have a lot of data I'm sending to the PLC and I'm using something like Sheet1.Comms1.D(10000) = Sheet1.Cells(1,1). However this doesn't tell me if the data was delivered correctly. Do you know of some way to get a confirmation that the data was all delivered?
Berti Baker Posted March 18, 2011 Report Posted March 18, 2011 Hi, If you use the "GetData" command then the OnData command parameters can tell you if the data is 'bad quality'. To test it try pulling the comms lead out There is also an interesting property on the Comms1 controll called DisplayErrors. If you set this to false you can catch and handle all script errors yourself. Regards, BB
