Hi there,
I am fetching some data(basically energy consumption-kWh) from Schneider make power monitor EM7230 over a modbus with CIP generic message instruction from integer to Real data type with COP. Voltage/PF/Current shows good values so far. But the energy consumption reading is showing -1.QNAN. I have read about this QNAN saying it is not a number or invalid number or the number is devided by 0 or kind off....
Can anybody share, how to resolve the same? As I am just copying the data from device to device, and there is no compution in logix regarding this fetch.
