Operating mode selection – setting of process data objects (PDO)
The process data to be transmitted (PDO, ProcessDataObjects) can be selected by the user
• via the "Predefined PDO Assignment" selection dialog; see fig. (E) below. The EL1512 offers a choice
of two different "Predefined PDO Assignments":
◦
"1Ch.+/-Counter":
0x1A02 and 0x1602 (marked in blue in the figure below)
◦
"2Ch. Counter":
0x1A00 and 0x1600 for channel 1, 0x1A01 and 0x1601 for channel 2 (marked in
red in the fig. below)
• These can be selected for individual PDOs by selecting the Sync Manager (see fig. A below) and then
activating the PDOs (see fig. B below).
Exclusion criteria prevent irregular combinations. Excluded PDOs have a grey background. Therefore,
for example, the PDO 0x1A02 cannot be selected as long as 0x1A00 and 0x1A01 are activated.
These changes become effective after activation and an EtherCAT restart or a reload.
The assignment of the PDOs to the respective Sync Manager is displayed in the "SM" column in the "PDO
List" (see fig. C below). The contents of the PDO selected in the "PDO List" are displayed in the "PDO
Content" field (see fig. D below). An overview of the assignment and contents of the PDOs can be found in
the chapter "
EL1512 PDO assignment [

".
The active PDOs are displayed in the TwinCAT tree (F) and can be linked.
A detailed description of the PDO selection can be found in the chapter "
