e) Create the PDO by setting bit
exists
(most significant bit) of sub-index 01h of the
according PDO communication parameter to 0b
The CAN-4AOUT can support up to four RPDO messages. All RPDOs on the controller
use the similar default communication parameters, with the PDO IDs set according to the
pre-defined connection set described in DS-301. Some RPDOs do not exist, there is no
RTR allowed, they use 11-bit CAN-IDs (base frame valid) and they are all event-driven.
While all four have valid default mappings defined (see below) only RPDO1 is enabled by
default (i.e. RPDO exists).

None of them have the timeout feature enabled, i.e. the “Event Timer” on sub-index 5 is
set to zero. When this is changed to a non-zero value, if the RPDO has not been received
from another node within the time period defined (while in Operational mode), a network
fault is activated, and the controller will go to the operational state define in Object 1029h
sub-index 4.
