similar PDO, it is possible to allocate this a set of bit-standardised variables (type "BOOL"). Here, too, a
"Goto Link Variable” from the context menu of a PDO can be executed in the other direction, so that the
respective PLC instance can then be selected.
Activation of the configuration
The allocation of PDO to PLC variables has now established the connection from the controller to the inputs
and outputs of the terminals. The configuration can now be activated with or via the menu under
"TwinCAT" in order to transfer settings of the development environment to the runtime system. Confirm the
messages "Old configurations are overwritten!" and "Restart TwinCAT system in Run mode" with "OK". The
corresponding assignments can be seen in the project folder explorer:
A few seconds later the corresponding status of the Run mode is displayed in the form of a rotating symbol
at the bottom right of the VS shell development environment. The PLC system can then be started as
described below.
Starting the controller
Select the menu option "PLC" → "Login" or click on to link the PLC with the real-time system and load
the control program for execution. This results in the message "No program on the controller! Should the
new program be loaded?" , which should be acknowledged with "Yes". The runtime environment is ready for
program start by click on symbol , the "F5" key or via "PLC" in the menu selecting “Start”. The started
programming environment shows the runtime values of individual variables:
