Exampleofprogramswithonlyramp-upsegments
WhenRamp-prioritizedPVstartistheselectedstartcondition,thecontrolprogram
pattern ramp is the start trigger. The control 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.
The retransmission program pattern will start at the same time as the control program
pattern does. For example, if B1 is the selected start point for the control program
pattern, B2 will be that for the retransmission program pattern.
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.
