When using program control, set the items that include “Program control: On” in “Basic
control settings” indicated above. Then, carry out the following settings in addition to
“Target setpoint/PID parameter settings.”
Settings for program control
Pattern initial setting
Wait action setting
Pattern start setting
Program pattern setting
Event setting
Event output setting
Repeat action setting
Pattern initial setting:
Set the pattern numbers, pattern off/on, number of
segments used, segment assignment method, edit
segment number, and Loop number.
Pattern start setting:
Set starting target setpoint and start code (operation
start condition).
Program pattern setting:
Set segment numbers, ramp/soak, final target setpoint,
segment time, ramp-rate-time unit, ramp-rate, segment
PID group numbers, operation at the time of segment
switching, wait operation type, and wait numbers.
Wait action setting:
Set wait zone off/on, wait zone settings, and timer.
Event setting:
Set event types, loop number/type/setpoint (only when
PV event is selected), time event ON/OFF, ON time/OFF
time (only when time event is selected) and hysteresis of
PV event.
Event output setting:
Set the event type, relay output ON/OFF, and relay
output number.
Repeat action setting:
Set the repeat function, number of repetitions, start
segment number, and end segment number.
