(24) Control Register+96: Set Point (SP) when Program Control Starts
The set point (SP) when program control starts can be configured. The program control starts with this set
point (SP) when the SP start is selected as the program control mode start type.
(25) Control Register+92: Step Time Unit
Minute or second can be selected as the unit of program control progressing time.
(26) Control Register+93: Program End Action
The action to be taken when the program control is terminated can be selected. The program control is
terminated when all steps 0 to 9 are performed and finished. Each step is performed with the parameters
configured for each step. Steps to which step time 0 is configured are also performed. For example, if the
program control of 4 steps is required, configure parameters of steps 0 to 3 and set the step time of the
remaining steps 4 to 9 to zero.
Terminate program
control
When the program control is terminated, the program end output bit is
turned on and maintained, and the PID module will be in standby status.
The program control can be executed again by turning off to on the
program control bit (operation parameter bit3).
During the program control standby (waiting for program control run)
status, the control output is turned off, and the operating status is not
updated except the over range, the under range, and the program end
output.
Continue program
control (Repeat)
When the program control is terminated, the program control is repeated
from step 0 as many times as the configured number of repeats. When the
step 9 of the last program control cycle is performed and finished, the
program end output bit is turned on and maintained.
Hold program control
When the program control is terminated, the program control is held at the
last status of step 9. The program end output and program hold bit are
turned on and maintained. While the program control is held, the fixed
value control is performed with the set point (SP) of step 9.
If advance next function (operation parameter Bit6 is turned off to on) is
executed while the program control is held, the program control is started
again from step 0. The program end output and program hold bit are
turned off.
While the program control is being held, the parameters of Blocks 10 to 19
and 30 to 39 can be changed. The program control can be executed again
after changing the program parameters, such as the set point (SP) or step
time of each step.
(27) Control Register+97: Number of Repeats
The number of repeats for the program control can be configured.
