Example of programs with only ramp-up segments
The program pattern contains points A1 to E1.
For some PV, the program advances through the segments up to the point at which the
ramp is reversed.
When the program operation starting point is set to A1, program operation is performed
for one control period, and program operation ends according to the junction code (JC)
for segment 2.
