EKD 316C – Parameter identification (Modbus)
Lock - the value can only be changed when the main switch is off
PNU - equivalent to to the modbus register no. (modbus adress + 1).
Actual value
Values are read/written as 16 bit integer values without decimals. This is the default value as read via modbus.
Scale
This shows the scaling factor of the value. *1 means that there is no scaling. *10 means that the read value
is 10 times larger than the actual value.
