4 — PDO COMMUNICATIONS
e Curtis eXm is easily controlled and monitored through two xed communication packets.
Each data packet contains 8 bytes. One is received by the eXm from another module (usually the
system manager) and in response, the eXm 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 Curtis CANopen implementation requires that the incoming RPDO1 (RX) be responded to
by an outgoing TPDO1 (TX). e eXm will respond to the RPDO1 (RX) with its TPDO1 (TX)
within 4 ms.
e eXm normally requires that the RPDO1 (RX) be cyclic from the manager. e cycle time
must be less than the programmed PDO Timeout. If the RPDO1 (RX) is not received within the
programmed time, the eXm will ag a fault and the eXm will disable all output drivers. If the PDO
Timeout parameter is set to 0, the timeout fault is disabled and the eXm will respond to any PDO
incoming at any rate without faulting. Take care using this setting as the last PDO commands will
stay on the eXm indenitely.
e 1352’s TPDO1 (TX) can also be set to cyclical transmission every 4ms to 1000ms rate as soon
as the eXm put in Operational Mode. Finally, the TPDO1 (TX) can be set to one of 5 types. Each
type sends a dierent set of internal data. Type 0 is the present default.
