I`m trying to implement a scaling factor to a parameter in real-time, where I would like to multiply and divide by 10 when I read and write to a PLC using Modbus RTU comm. To achieve this, I set the Tag numDiv to 0.1 and numAdd to 0 using the setTagDisplayUnit function. When I test the parameter, I notice that the value I enter into the keypad does not get scaled but the value being displayed is scaled. According to the help docs what should happen is the value I enter should get multiplied (in this case by 10) and the value being displayed should be divide by 10.
Is there something I am doing wrong here??
Thanks,
SP
