4.2.1.20 Object 2014-2017h: 1st-4th Mask 1 to 4 for Transmit-PDO
In order to reduce the bus loading with event-triggered PDOs, masking can be used to switch off the
monitoring for individual bits in the PDO. In this way it can be arranged, for instance, that actual
position values are only signaled once per turn.
This Object masks the PDO-channels 1 to 4. If only two bytes have been defined in a PDO, then it
masks just two bytes, although 4 bytes of mask information have been transmitted.
An activated bit in the mask means that monitoring is active for the corresponding bit in the PDO.
