Exclusive Control in a Process
This primarily uses the communication command macro and scene control macro.
Macro customize functions can be used to perform exclusive control in a process when a program is executed.
Exclusive control must be performed during measurement and communication in order to prevent incorrect
processing, such as a communication command or screen operation accidentally changing the scene during
measurement, or subsequently received data overwriting the currently received data.
Exclusive Control in a Measurement Process
When executing the setting or acquisition of processing unit data, system data, or other data in a program,
and when executing a process that changes scene data such as a scene change, you must first stop
acceptance of measurement triggers during processing.. If data setting, data acquisition, or a scene change
is executed when measurement triggers can be accepted and a measurement trigger is then input during the
setting process, acquisition process, or scene change, there is a risk that data inconsistencies will occur or an
incorrect measurement result will be output. .
To stop acceptance of measurement trigger input, use the MeasureStop function. To enable acceptance of
measurement trigger input, use the MeasureStart function.

• When executing a scene change or setting or acquiring processing unit data or other data in a program, always
execute MeasureStop beforehand. If data setting or data acquisition is executed without executing MeasureStop,
there is a risk that measurement may be executed during the setting process or acquisition process and cause
inconsistencies in the data being set or acquired.
• If MeasureStart is not executed after MeasureStop, it will not be possible to accept measurement triggers. The BUSY
signal will remain ON.
• If measurement is to be executed after MeasureStop in a program, execute MeasureStart before executing
measurement. If MeasureStart is not executed after MeasureStop, measurement will not take place when executed.
• With the unit macro or unit calculation macro, create a program that does not require exclusive control. Switching
between the measurement prohibited state and measurement acceptance state during measurement execution may
cause unexpected operation.
