If the terminal is selected in the System Manager (A), the
Process data
tab (B) shows the PDO selection.
The two SyncManagers of the inputs (SM3) and outputs (SM2) can be changed (C). If one of the two is
clicked on, the PDO possible for this SyncManager appears underneath it (D). PDOs that are already
activated have an activated checkbox in front of them; this is activated by clicking on it.
The process data which then belong to the device are listed underneath it (G). So that the individual bit
meanings are visible, e.g. in the
Status
status word, and can be separately linked (G),
ShowSubVariables
must be activated in the System Manager (F). The bit position at which the subvariables are located in the
status or control word
Ctrl
) can be taken from the address overview (H) or the following information.
Predefined PDO Assignment
In order to simplify the configuration, typical configuration combinations of process data are stored in the
device description. The predefined configurations can be selected in the process data overview. Therefore
the function is available only if the ESI/XML files are saved in the system (
downloadable from the Beckhoff
).
The following combinations are possible (see also Fig.
