SET SDO CLIENT:
By pressing the “
Set SDO Client ” button from the main window for SW67156 (Fig. 2) the window “Set SDO Client Access” appears (Fig. 5a
and 5b).
With the SDO Client the HD67156 Gateway 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 SNMP array. The second part is used to write, using the SDO, the data present in the SNMP 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 SNMP array where coping the first byte of the SDO read is defined;
In the field “ Address Byte2 ” the address of the SNMP 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 SNMP 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 SNMP 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.
