Camel Posted August 19, 2005 Report Posted August 19, 2005 I am working on a project using UNITY PRO and the Wonderware I/O server Modicon MODBUS Ethernet v7.6.0.0. I have tried using IEC addressing in our Wonderware app. but it seems the I/O server only reads analog values. But, if I use standard addressing, it works fine. Doing it this way I am working with one table of variables with IEC addressing and one in standard addressing. I haven't really taken a looksy, but I don't think you can change between standard and IEC in UNITY. Anyone have any thoughts? Quote
