If you want to delete a module, select the module and press . If you
want to copy a selected module from the worksheet, including the settings,
click Copy on the function bar and then Paste. To replace a module with a
different module – such as a generator with a hardware input – right-click the
Generator and select Replace Module from the context menu. DASYLab
lists all available data sources that you can use to replace the generator. For
example, select Inputs/Outputs\NI-DAQmx\Analog Input for an
NI-DAQmx Analog Input. The module connections and the module name
remain the same after the replacement.

You can connect modules semi-automatically or manually. If you want to
connect several data channels simultaneously, use the semi-automatic
connection method. To do so, move the module inputs to the outputs of the
neighbor module on the left. DASYLab connects the data channel terminals
that are exactly opposite each other. You also can use this method if the
number of inputs of the module receiving data is not the same as the number
of outputs of the modules providing data, or if you do not want to connect all
inputs. You can connect other modules to the remaining free connections.

Use the manual connection method if you want to branch a data
channel. To do so, click a data channel. The cursor changes its
appearance to a hand with a plug symbol. Move this plug, for
example, to the input of a scaling module to convert the acquired

raw data. If you connect modules manually, the direction of the new data
channel is important: You connect a module input with another module
output, or you branch a data channel to a module output, or you connect a
module input with a data channel. Every data channel can have up to 15
nodes.

If you clicked the input or the output of a module without wanting to establish
a connection, you can terminate the action by clicking anywhere in the
worksheet.

If you want to delete a data channel, right-click the data channel twice. With
the first click the data channel changes its color and with the second click
DASYLab deletes the data channel. To delete all the module data channels,
right-click the module and select Delete Input Connections or Delete
Output Connections
.

DASYLab does not permit open inputs, and in DAP boxes DASYLab does
not permit open outputs or open inputs. The Read Variable module ensures
that the worksheet always meets this requirement before the measurement
