All network variables can also be accessed via "Service Data Object"
(SDO).
Mapping to Process Data Objects (PDOs) can also be carried out via
SDO. However, in the interests of diagnosis, simplification and
avoiding errors we strongly recommend using the CANopen
configurator, ProCANopen.
When PLC stop occurs, all network variable outputs
(QW) are set
to 0.
Network variables are read in and output like a
process map using the CANIO driver.
Direct network variables are read in and output
without process map.
