I have a Watlow PM that I can see over MAX now and using the EZ zone code can get manufacture info from. I also am using (for the first time) the add-on Modbus over serial tool from Saphire to try to write or read anything from it and I always get a "time out" error from the slave. I tried to do a simple VISA read as I found on some posts and I get the same time out error. It seems if I try anything from Labview I get this error. I even tried writing Hex to the thing with the same results. Can someone throw me a bone?
