13. How to make the program pattern table
Before setting the program, make a program pattern and data table.
Copy the program pattern table and follow the procedure mentioned below.
(1) Write down the program pattern number.
(2) From Step 1, write down step SV and time of each step in sequence.
(3) Write down Alarm 1 (A1) and Alarm 2 (A2) action points and Time signal output time.
(4) Write down the P, I, D, ARW and proportional cycle values.
(5) Write down the Wait value and Wait function Used/Not used of each step.
(6) Draw a line graph of the step SV.
Explanation of the program pattern table
Program pattern table consists of Y axis which represents the step SV ( or )
and X axis which represents the step time (Hour:Min or Min:Sec).
In this context, Step SV is considered to be the value at the end of the step, and
step time is considered to be the step processing time.
The relation between the step SV and step time can be explained as follows.
Step 1: The control is performed so that the temperature reaches 500 in 30 minutes
(0:30). (*1)
Step 2: The control is performed at 500 for 1 hour (1:00).
(*1) When the control starts, SV differs depending on the program control start form.
If the SV start is selected in the Program control start form selection, the control
starts from SV. If the PV start is selected in the Program control start form selection,
the SV is advanced to the PV and the control starts.
