SET PDO ACCESS:
By pressing the “
Set PDO Access
” button from
the main window for SW67D20 (Fig. 2) the
window “Set PDO Access” appears (Fig. 7a and
7b).
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 " Receive PDO"
and the " Transmit PDO ". The first part is used
to receive PDO in the CANopen network and
copy the data in the internal
array. The second
part is used to transmit PDO in the CANopen
network with the data of internal
array.
The data of the columns in the “Receive PDO”
have the following meanings:
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 "
Add B1
" the first byte where the data will be saved in the internal array is defined;
In the Field "
Add B2
" the second byte where the data will be saved in the internal array is defined (only if
Dimension
> 1);
In the Field "
Add B3
" the third byte where the data will be saved in the internal array is defined (only if
Dimension
> 2);
In the Field "
Add B4
" the fourth byte where the data will be saved in the internal array is defined (only if
Dimension
> 3);
In the Field "
Add B5
" the fifth byte where the data will be saved in the internal array is defined (only if
Dimension
> 4);
In the Field "
Add B6
" the sixth byte where the data will be saved in the internal array is defined (only if
Dimension
> 5);
In the Field "
Add B7
" the seventh byte where the data will be saved in the internal array is defined (only if
Dimension
> 6);
In the Field "
Add B8
" the eighth byte where the data will be saved in the internal array is defined (only if
Dimension
> 7);
The field “
TimeOut
” is used for put at zero the data into LoRaWAN if the PDO doesn’t arrive with a frequency less than the time
expressed in the field. If the value in the field is 0, it means that you don’t want to use this feature, and so the value is never
deleted;
In the field "
Mnemonic
" the description for the PDO is defined.
