I am defining the value as 32 bit floating number and saving it in VD2020. But the value of VD2020 is not transferring correctly to TD200. There is some difference. May be its due to delay, because the pressure is changing very fast. Kindly help me so that i can get correct value on TD200 Screen. Regards,
