FLOWDATA Reference
What is FLOWDATA?
The ZS series implements high speed sampling measurement up to 110us.
Handling these measurement data with an external device requires reading in a large
amount of data.
The ZS series are provided with a mechanism which enables to handle and acquire
measurement data by a given bundle.
This bundle of data is called a FLOWDATA.
■ How to acquire FLOWDATA
FLOWDATA is batch output if the controller has accepted the command for acquiring a
FLOWDATA when data is accumulated for the specified buffer size (max. 1000 data).
A device receiving data (such as PC) needs to issue the command before the ZS con-
troller accumulates measurement data for the buffer size.

If the controller has not received the command when measurement data for the buffer size is
accumulated in the controller, the past data is overwritten:
In this case, it raises an error flag for buffer overflow. A device receiving data (such as PC) needs
to check this flag to see if the commands have been issued in time.
