Several terminals / modules generate the entry from object 0xF081:01 in the Start-up list automati-
cally (see fig. "Download revision in Start-up list").
The object 0xF081:01 (Download revision) describes the revision of the terminal / module, e.g.
0x0018000A for EL7201-0010-0024, and is necessary to ensure compatibility.
Please note, that you must not delete this entry from the Start-up list!

7.3.7.2 Detailed description of Process Data tab
Sync Manager
Lists the configuration of the Sync Manager (SM).
If the EtherCAT device has a mailbox, SM0 is used for the mailbox output (MbxOut) and SM1 for the mailbox
input (MbxIn).
SM2 is used for the output process data (outputs) and SM3 (inputs) for the input process data.
If an input is selected, the corresponding PDO assignment is displayed in the PDO Assignment list below.
PDO Assignment
PDO assignment of the selected Sync Manager. All PDOs defined for this Sync Manager type are listed
here:
• If the output Sync Manager (outputs) is selected in the Sync Manager list, all RxPDOs are displayed.
• If the input Sync Manager (inputs) is selected in the Sync Manager list, all TxPDOs are displayed.
The selected entries are the PDOs involved in the process data transfer. In the tree diagram of the System
Manager these PDOs are displayed as variables of the EtherCAT device. The name of the variable is
identical to the Name parameter of the PDO, as displayed in the PDO list. If an entry in the PDO assignment
list is deactivated (not selected and greyed out), this indicates that the input is excluded from the PDO
assignment. In order to be able to select a greyed out PDO, the currently selected PDO has to be deselected
first.
Activation of PDO assignment
ü If you have changed the PDO assignment, in order to activate the new PDO assignment,
a) the EtherCAT slave has to run through the PS status transition cycle (from pre-operational to
safe-operational) once (see Online tab [} 94]),
b) and the System Manager has to reload the EtherCAT slaves
