Chapter 3 Programming

Start/Stop
Counter is started or stopped by the variable (%QX) configured in “Enable” in configuration window. While this
variable is TRUE, counter is enabled. No function block is required to start or stop.
Read counter value
CPU ROM VER.3.5.3.41 or older
Counter value is stored automatically in the variable (%ID) configured in “Counter” in configuration window. No
function block is required to read counter value.
CPU ROM VER.3.5.3.42 or newer
It is recommended to use a dedicated library instead of the variable (%ID), because later counter value can be read
than the variable. Refer to the following description.
Library to operate counter
Dedicated library must be added to the project to read/write counter value and preset values.
Double click on “Library Manager” or right click and choose “Edit Object”. Library Manager window appears.
Click “Add library” and choose “CmpHIESLib_MV”.
CmpHIESLib_MV library is added in the project.
