Concept of program
This section describes the concept of programs using process control instructions.
Program example using the S.2PID instruction in an execution cycle of 1 second
For specific program examples using process control instructions, refer to the following.
Page 2077 Process Control Program Examples
(1) Setting loop tag memory
(2) Setting operation constants
• Setting data for S.IN, S.PHPL, S.2PID, and S.OUT1
(3) Measuring the execution cycle
(4) Setting input data (PV)
• Reading PV from such as the A/D conversion module
(5) MV output
• Outputting MV from such as the D/A conversion module
(6) Specifying process control instructions
• S.IN instruction
• S.PHPL instruction
• S.2PID instruction
• S.OUT1 instruction
(7) Setting loop tag memory
(8) Setting operation constants
(9) Executing a command
(1s)
