4 — PDO COMMUNICATIONS
e 1353 is controlled and monitored through four xed communication packets. Each data packet
contains 8 bytes. Two are received by the 1353 from another module (usually the system manager)
and in response, the 1353 sends out its packet of data. CANopen calls these packets Process Data
Objects (PDOs). PDO messages have a medium priority.
e PDO communication packets conserve bus bandwidth by bundling the values of a group of
objects into a single message. e content of these PDOs is xed, thus simplifying the interface.
e 1353 normally requires that the PDO-RX be cyclic from the manager. e cycle time must be less
than the programmed PDO Timeout. If the PDO-RX is not received within the programmed time,
the 1353 will ag a fault and disable all output drivers. If the PDO Timeout parameter is set to 0, the
timeout fault is disabled and the 1353 will respond to any PDO incoming at any rate without faulting.
