3. Programming
This chapter explains how to create programs by citing specific examples. Create
user programs by referring to the given programming examples. Use the parameter
map included in “3.5 Program Parameter Map,” in order to further familiarize your-
self with the required operations.
Be sure to carry out the settings instructed in “2. Initial Settings” before beginning
any of the tasks discussed in this chapter.
3.1 Overview of Program Patterns
■
Programming Overview
The programming example given here demonstrates how to do the tasks outlined below.
1. Program the controller to start program operation at 25
⬚
C and raise the temperature
up to 80
⬚
C in 20 minutes.
2. When the temperature reaches 80
⬚
C, keep it at this level for 80 minutes.
3. Finally, lower the temperature to 0
⬚
C in 10 minutes.
Event output
• Set a deviation of 5
⬚
C on both the positive and negative sides of a program setpoint to
allow the controller to output an event signal if the temperature goes beyond the
deviation range.
• Let the controller output an event signal when the temperature stabilizes to 80
⬚
C.

The output turns on after 20 minutes have elapsed since the start of program operation.
Then, it turns off after 100 minutes have elapsed from the start of program operation.
