Mapping a Variable to the Oscilloscope
A probe (variable) can be directly plugged or mapped from within the Oscilloscope:
- Right-click on any channel (already mapped or not) in the channels list and select the Map option to open the Scope Variable Selector.
If your application is not connected and running, the following message is displayed.
- Navigate through the available variables and select the one you want to connect to the channel

The Scope Variable Selector contains only the PLC"Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events variables that are eligible for the softscope (i.e. BOOL, INT, SINT, DINT, LINT, UINT, USINT, UDINT, ULINT, BYTE, WORD, DWORD, LWORD, TIME and LREAL, as long as they are not in a UDFB instance).
Additionally, only a subset of variables are displayed (e.g. ActualVelocity 1 is not visible), when in Simulated mode.

- (Optional) Set the Derivation Order.
- (Optional) Set the Derivation Period. The value entered should be either
0.0
(no modulo) or the Modulo Period, e.g. 360.0.
If the selected Derivation Order is greater than zero, the Derivation Period of the selected signal can be used to remove rollover spikes in the derivative value if the variable is of a periodic nature as the result of "modulo" behavior.

You can also disconnect a probe as follows:
In order to unmap a variable, or unplug a probe:
- Right-click on the channel you wish to remove from the channels list and select the Unmap command in the menu to disconnect the probes.
- Select the Unmap all Oscilloscope Channels command from the right-mouse menu in the Dictionary or the PipeNetwork.
