The Data Reduction Modules Group
The data reduction modules group contains modules for reducing large data
quantities to specified characteristic values or data sections.
The modules Average and Block Average reduce data blockwise to mean
values or to extreme values.
Use the Separate module if the sampling rates are high in order to output just
one value from each data block or to output just one data block after a number
of rejected data blocks. The Cut Out module outputs only a specific number
of the first values in every data block.
The Multiplexer module combines several data channels into one data
channel whereas the Demultiplexer module distributes one data channel
onto several data channels either value-wise or blockwise.
The Signal Switch module changes the data input either time-controlled or
amplitude-controlled in order to only output data of the active data channel.
The Circular Buffer module saves incoming data and outputs the data
event-driven. In contrast the Shift Register module collects the values of
every data block and then outputs the new data block event-driven.
The Network Modules Group
The network modules group contains modules for exchanging data and
messages in networks. If your installation includes the DASYLab net license,
you can use up to 32 network modules in one worksheet.
Multiple DASYLab programs that are installed on different computers in one
network can communicate using the modules Net Input and Net Output.
Use the Message module to create messages or warnings which you can send
via the Message Output module to a Message Input module in the
worksheet on another computer in the network.
The modules DataSocket Import and DataSocket Export exchange data
with OPC servers and National Instruments DataSocket servers.
