We have a LV DSC PLC application that has over 3000 variables. We are having great difficulty getting data out of arrays. LV will write the first element, but all the other elements are 0. I cannot read anything. My coworker called RSLinx customer support and they told him that arrays "are not possible" in out RSLinx OPC server. Has anyone else experienced this? I find this extremely hard to believe.
Do you have to use RSLINX for your opc server?? Kepware shows that it can handle arrays of data for some of the allen bradley ethernet data types. What data types are you trying to read? One possibility is to use a string datatype with a length of 100 bytes or more, then convert the string bytes to numbers. Only catch is that the values must all be greater than 0. An ascii nul value terminates the string.
