Sampling rate: It is used to set data display time for Real-Time Viewer. User can select
One from the following for real time monitoring.
Time out: This is time set for generating time out errors related to real time viewer
Communication.
For example, if Recorder and PC with data acquisition software are located at
different places connected through Ethernet across different gateways, and then user can
adjust sampling rate and time out settings to avoid errors in communication. When real time
Viewer is running, please observe the following taskbar at the bottom side of the screen.
Here, scan time should always be less than sampling rate. Otherwise,
communication errors will occur. If PC and Modbus slave devices are connected by long
distance network, then there might be chances that scan time gets increased. So check this
and set sampling-rate more than scan time. Also user can set time out settings to generate
Communication failure errors. Maximum time out settings possible is 60 sec. For example,
scan time is adjusted and time out setting = 30 sec. This means, if scan time is more than
sampling rate for more than 30 sec, then communication errors will be generated.
