Is there a way to have multiple PDM's running on the same CAN
Hi there, you can have multiple PDMs on the same CAN bus as long as their CAN bus speeds are the set the same. You can then send information between the PDMs if required.
So it best to think of it as master & slave so then you have to create custom can messages to get the information from the slave pdm
The communication can go in both directions between the PDMs. For instance you could set up a CAN output on PDM1 to send an input voltage. The on PDM2 you could set up a CAN input to receive that CAN frame and use the data as needed. The same would work in the other direction too, you just need to make sure that each PDM is sending the CAN frames with different IDs to the other.
