Chapter 8: Programming

This chapter explains about programming for QE81WH.
When you apply sample programs introduced in this chapter into the actual system, make sure to verify
in advance that there is no problem with the target system control.
Follow the procedure in Figure 8.1-1 to create a sample program using QE81WH.
The default setting allows you to use either GX Works2 (refer to 7.6), GX Developer (refer to 7.7) or the
sequence program to make setting; however, if the setting is made for the first time by using GX Works2
or GX Developer, the program for initial setting can be eliminate, which will reduce time for scanning.

8.1 Programming procedure

Follow the procedure in Figure 8.1-1 to create a program for acquiring the measured data, alarm
monitoring, calculating periodical electricity amount using QE81WH.
Do you make the initial setting
manually on the GX Works2 or
GX Developer?
Measured data acquisition program
(Acquiring the electric current, electric energy amount, etc.)
Program for periodic electric energy function
(Instruction as to whether or not to measure the periodic electric
energy)
Alarm monitoring function program
(Acquiring the alarm status and output in case of alarm
occurrence)
Error monitoring program
(Monitoring the error status and output in case of error
occurrence)
