GET_LOCAL_NODE_ID (FB) ¶ FUNCTION_BLOCK GET_LOCAL_NODE_ID EXTENDS CiA405Base Function block returns the NodeID of the local device (= CANopenManager) InOut: Scope Name Type Initial Comment Inherited from Input NETWORK USINT 1 CAN network number the function block should operate on. Note: It is not the same like the network number in CANBus configurator. The CiA405 NETWORK is calculated by NetID + 1.

Query state ¶ GET_CANOPEN_KERNEL_STATE (FunctionBlock) GET_STATE (FunctionBlock)

GET_CANOPEN_KERNEL_STATE (FB) ¶ FUNCTION_BLOCK GET_CANOPEN_KERNEL_STATE EXTENDS CiA405Base Gets the current state of the CANopen Kernel. As long as CANopen network is running correctly the function block returns CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_NO_ERROR for output STATE . The function block detects bus errors, configuration errors, guarding errors and internal system errors (e.g. out of system memory). InOut: Scope Name Type Initial Comment Inherited from Input NETWORK USINT 1 CAN network number the function block should operate on. Note: It is not the same like the network number in CANBus configurator. The CiA405 NETWORK is calculated by NetID + 1.

GET_STATE (FB) ¶ FUNCTION_BLOCK GET_STATE EXTENDS CiA405Base Function block returns the CANopen state of device with NodeID DEVICE . The ourput STATE is defined as follows: If guarding/heartbeat is not active for the selected DEVICE : DEVICE_STATE.NOT_AVAIL is returned if DEVICE doesn’t respond in configuration phase. DEVICE_STATE.UNKNOWN is returned in all other cases even if a boot-up message was received. If guarding/heartbeat is not active but at least one cyclic synchronous TPDO is configured for the selected DEVICE : DEVICE_STATE.NOT_AVAIL is returned if DEVICE doesn’t respond in configuration phase. DEVICE_STATE.OPERATIONAL is returned if cyclic synchronous TPDOs are received correctly DEVICE_STATE.UNKNOWN is returned in all other cases. If guarding/heartbeat is active: If there is no guarding/heartbeat error (due to timeout) received NMT state is returned. DEVICE_STATE.NOT_AVAIL is returned if device is not responding or in case of huarding/heartbeat error.

SDO_READ4 (FB) ¶ FUNCTION_BLOCK SDO_READ4 EXTENDS CiA405Base This function block is used for reading a specific object from object dictionary of a DEVICE . Up to 4 bytes can be read.
