CHAPTER 7 PROGRAMMING
This chapter describes the programs of the Q64TCN.
When applying any of the program examples introduced in this chapter to the actual system, verify that the control of
the target system has no problem thoroughly.
7.1 Programming Procedure
Create a program that performs temperature control in the Q64TCN using the following procedure.
*1 In the standard control, the self-tuning can be selected if necessary.
Configure initial data (such as input range
and set value (SV)) using GX Works2.
Start
Create a sequence program to configure
initial data (such as input range and set
value (SV)).
Configure
the initial setting using
GX Works2?
YES
NO
NO
Use specific PID constants?
YES
Use specific PID constants?
YES
Configure the PID constants using
GX Works2.
Create a sequence program to
configure the PID constants.
Operation
Execute the auto tuning
*1
.
NO
Back up the PID constants in E
2
PROM.
Use CH E
2
PROM's PID constants read
instruction to create a sequence program
to read the PID constants from E
2
PROM.
Execute the auto tuning
*1
.
Back up the PID constants in E
2
PROM.
