SET SDO CLIENT (Hardware With Ethernet):
By pressing the "Set SDO Client" button from the main window for SW67551 (Fig. 2) the window "Set SDO Client Access" appears (Fig. 6a
and 6b).
With the SDO Client the HD67551 Converter can read and/or write the data from other devices connected in the network CANopen.
It is divided in two parts, the " SDO Read" and the "SDO Write". The first part is used to read, using the SDO, the data in another device and
then put them in the PROFIBUS array. The second part is used to write, using the SDO, the data present in the PROFIBUS array to others
CANopen devices.
The data of the columns in the "SDO Read"
have the following meanings:
In the field "Device ID" insert the ID
of the device to read;
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 "N Byte" the dimension
of the SDO is defined (it can be 1, 2,
or 4);
In the field "Poll Time" insert the
cyclic time to make this request;
In the field "Address Byte1" the
address of the PROFIBUS array
where coping the first byte of the SDO read is defined;
In the field "Address Byte2" the address of the PROFIBUS array where coping the second byte of the SDO read is defined (only if N
Byte is 2 or 4);
In the field "Address Byte3" the address of the PROFIBUS array where coping the third byte of the SDO read is defined (only if N
Byte is 4);
In the field "Address Byte4" the address of the PROFIBUS array where coping the fourth byte of the SDO read is defined (only if N
Byte is 4);
In the field "Mnemonic" the description for the SDO is defined.
