Set Sdo Server - ADF Web HD67551 User Manual

Industrial Electronic Devices
SET SDO SERVER (Hardware Without Ethernet):
By pressing the "Set SDO Server" button from the main
window for SW67551 (Fig. 2) the window "Set SDO
Server Access" appears (Fig. 4).
This window is made to create the SDO in read or write in
the CANopen side, and to indicate which bytes are
associated to these SDO.
It is divided in two parts, the "SDO in Read (PROFIBUS
IN)" and the "SDO in Write (PROFIBUS OUT)".
The first part " SDO in Read (PROFIBUS IN)" is used to
read, using the SDO, the data that arrived from the
Master PROFIBUS.
The second part " SDO in Write (PROFIBUS OUT)" is used to write, using the SDO, the data that will be sent to the Master PROFIBUS.
The fields in the two tables are the same:
In the Field "Index" the address for the SDO is defined;
In the Field "SubIndex" the second address for the SDO is defined;
In the Field "nByte" the dimension of the SDO is defined (it can be 1, 2, or 4);
In the Field "Address
PROFIBUS arrays is defined;
In the field "Swap" if it is necessary, it is possible to swap the SDO data;
In the field "Mnemonic" the description for the SDO is defined.
By pressing the "Create SWAP" button from the "Set SDO Server Access" window, the window
"Byte Swap" appears (Fig. 5). This window helps modify the "Swap" field.
For example in the Figure 4 scenario:
If you want to read the data from the PROFIBUS that are saved in the position 0 of the array, you can create a SDO with index 0x3000,
SubIndex 0x00, nByte 4 and Address PROFIBUS 0. In this way you are able to read 4 bytes starting from address 0 of the PROFIBUS array.
