Program example for trip information reading
Example 8 shows
a ladder logic to
read the trip information of station 1 inverter to D1.
Trip history No. 1, No. 2 reading code number: 74H (hexadecimal)
The reply code at the time of instruction code execution is set to D2.
For example of trip information
Read dara: 2D0EH
