Set Pdo Access - ADF Web HD67551 User Manual

Industrial Electronic Devices
SET PDO ACCESS (Hardware Without Ethernet):
By pressing the "Set PDO Access" button from
the main window for SW67551 (Fig. 2) the window
"Set PDO Access" appears (Fig. 7).
This window is made to create the Receive and the
Transmit PDO in the CANopen side, and to indicate
which bytes are associated to these PDO.
It is divided in two parts, the "Transmit PDO
(PROFIBUS IN)" and the "Receive PDO (PROFIBUS
OUT)".
The first part " Transmit PDO (PROFIBUS IN)" is
used to read and transmit in the CANopen
network, using the PDO, the data that arrived
from the Master PROFIBUS.
The second part " Receive PDO (PROFIBUS OUT)"
is used to write, using the PDO, the data that will
be sent to the Master PROFIBUS.
The fields in the two tables are the same:
In the Field "Cob-ID" the address for the PDO is defined;
In the Field "Dimension" the dimension of the PDO is defined (it can be between 1 and 8);
In the Field "Address PROFIBUS" the first byte where the data will be saved/loaded in the PROFIBUS arrays is defined;
In the field "Swap" if it is necessary, it is possible to create a swap of data bytes;
In the field "Mnemonic" the description for the PDO is defined.
