    Configuration of connected Woodward controls All COB-IDs used in the CAN network must be unique. Please make sure that a COB-ID is only configured once. If TPDO or RPDO COB-ID entries are referring to an already used COB-ID, either disable that PDO or change its COB-ID. Specific information for LS-5 controls The LS-5 CANopen parameters are configured using Woodward’s Toolkit software.
