Precautions for BCD Programming
1,2,3...
1.
With models with a BCD output, only the measurement value, maximum
value, or minimum value can be read out.
2.
The "+" and "
−
" polarity correspond to low and high of the POL signal.
3.
Read data while the D.V. is ON.
4.
Data cannot be written from the PLC to the Digital Indicator.
