The Module Groups
Twelve module groups with related modules contain the DASYLab
functions. The appendix provides an overview of the available modules and
their functions. The installed DASYLab license determines which modules
are available. Modules that are not part of your license are dimmed in the
browser. Refer to your DASYLab vendor to extend your DASYLab license.
The Input/Output Modules Group
The input/output modules group contains the hardware modules of the
installed hardware driver, and the interface modules for communication with
external devices and programs.
For example, if you have installed the NI-DAQmx driver for National
Instruments hardware, the associated modules are in the sub-folder
NI DAQmx. If you have installed the DAP driver for Microstar Laboratories
hardware, the associated modules are in the sub-folder DAP. If you have
installed the sound driver, you can select the sound driver under
Measurement»Select Driver and access the associated modules in the sub-
folder Driver.
The interface modules are in sub-folders with respective names. The sub-
folder OPC DA Client contains the modules OPC Input and OPC Output
to exchange data with OPC servers, which are registered on the network or
the local computer, via the OPC interface.
The sub-folder DDE contains the modules DDE Input and DDE Output to
exchange data and commands with other programs via the DDE interface.
The sub-folder ICom contains the modules ICom Input and ICom Output
to exchange data and text in a network via the TCP/IP interface.
The sub-folder ModBus contains analog modules and digital modules to
communicate with PLCs via the ModBus protocol.
