1-3-3 Operating Method
Setting with front keys is not required for models with a BCD output.
1-4 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.
1-5 Programming Example 1: Connecting to a PLC
The following programming example shows a single Digital Indicator con-
nected to the SYSMAC C500 (OMRON).
