This function determines whether LSP1 or PV is used as the setpoint
when the program is initially changed from HOLD to RUN.
The selections are:
DISABL = When the program is initially changed from HOLD to
RUN the present LSP1 value is captured as the default setpoint. If the
program is terminated or the power cycled before the program has
completed, the LSP1 is used as the control setpoint. The beginning
segment uses this value as the initial ramp setpoint.
ENABL = When the program is initially changed from HOLD to
RUN the present PV value is captured and used as the beginning
setpoint value for the ramp segment. If the program is terminated
before completion, the setpoint value will revert back to the PV value
captured at the initial HOLD to RUN transition. If the power is cycled
before program completion, upon power-up the setpoint is set to the PV
value at power-up and when the program is restarted that setpoint value
is used initially.
The Program State selection determines whether the program is in the
HOLD state or Disabled (DIS) after completion of the program.
The program termination state function determines the status of the
controller upon completion of the program. The selections are:
• LAST = controls to last setpoint
• FSAF = manual mode and Failsafe output.
When enabled, this selection allows you to reset the program to the
beginning from the keyboard.
