• System configuration
• Operation Process
1) High-speed analog input (immediate refresh)
4 to 20 mA signals from the displacement sensor are input to and
refreshed in the unit at every PRV instruction execution. The dis-
placement data is stored in the areas (Ex: DM) that have the I/O
memory.
2) Counting process with the ladder program
A ladder program has to be arranged (Ex: The unit compares the
ranges with BCMP instruction, and the unit counts rises of the re-
sults with INC instruction) so that the counter will count the number
of times of when the stored displacement data exceed a certain
threshold value. The execution of the program will make the unit
count.
