If i have an object mapped to a PDO in the canopen EDS and then i go to use the ros-canopen service "set_object" to modify its value, does ros-canopen use SDO or PDO to modify this value in the object dictionary of my device?
If you have mapped the object to a RPDO (of the device), it will be used to set the value. Otherwise SDO.
awesome. on another note. i very much admire the software acrhitecture used in ros-canopen. I am interested in learning a bit more and have some questions. Can i contact you in private with some questions? I know this isnt the appropriate place to ask but i dont know how else i would contact you lol
my email is jd224234@dal.ca , shoot me an email if this is a possibility
PDOs are used for fast communication and are sent cyclically while SDOs are not cyclic. PDOs should be used for sending real-time data and SDOs for configuration settings and services. Though PDO has higher priority than SDO but based on data type, a selection can be made. For service calls, SDOs can be used.
