Fundamentals and Applications of CANopen (Part 3) - Predefined Connection Set

1、CANopenPredefined Connection Set To reduce the configuration workload of simple networks, CANopen defines a mandatory default identifier (CAN-ID) allocation table. These identifiers are available in the pre-operational state and can be modified through dynamic allocation. CANopen devices must provide the corresponding identifiers for the communication objects they support. The defaultID allocation table is based on … Read more
