SET SDO CLIENT:
By pressing the “
Set SDO Client
” button from the main window for SW67835 (Fig. 2) the window “Set SDO Client Access” appears (Fig. 6a
and 6b).
With the SDO Client the HD67835 Gateway can read and/or write the data from other devices connected in the CANopen network.
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 DALI internal memory array. The second part is used to write, using the SDO, the data present in the DALI internal
memory array to the 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 SDO is defined;
In the field "

defined (it can be 1, 2, or 4);
In the field “

make this request;
In the field “

” the address of the DALI internal memory array where coping the first byte of the SDO read is defined;
In the field “
Address Byte2
” the address of the DALI internal memory 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 DALI internal memory 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 DALI internal memory array where coping the fourth byte of the SDO read is defined
(only if N Byte is 4);
In the field “
