(23) Control Register+91: Program Control Mode Start Type
Select the program control mode start type from the following:
When the program control is started, the time is advanced until the set point (SP) becomes
PV Start
equal to the process variable (PV), and then the program control starts.
When "Continue program control (Repeat)" is selected as the program end action, the time is
PVR Start
advanced until the set point (SP) becomes equal to the process variable (PV) at which
program control is terminated, and then the next program control starts.
When the program control is started, the program control starts from the set point (SP) that is
SP Start
configured as "Set Point (SP) when Program Control Starts."
Examples for the PV start, PVR start and SP start actions are described using the following program pattern.
