Hey guys, I have been using the Watlow F4 single channel controller for almost 2 weeks now and have encoutered a problem I can't solve. To read the temp I use R? 100,1 as the modbus protocol command to the GPIB. Most of the time it will read the correct temp on the LCD, but will sometimes glitch on some numbers. For example, when the temperature is at a constant temp of 29, the LCD will show that number bu t the labview visa read will show it as "29" or "2;" randomly. The issue also occurs for "49" making it "4=" or "85" to "8=". Any help and adivce would be appreciated.
