SDO_READ_DATA (FB) ¶ FUNCTION_BLOCK SDO_READ_DATA EXTENDS CiA405Base This function block is used for reading a specific object from object dictionary of a DEVICE . If object can be read without error CONFIRM becomes TRUE and DATA contains read data in Little Endian byte order. If an error occurs ERROR becomes unequal 0. In case of a SDO abort ERROR is set to CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_OTHER_ERROR and ERRORINFO contains the associated abort code (in Little endian) as defined by CiA 301. 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. Example: 1 = CAN0, 2 = CAN1, 3 = CAN2, … CiA405Base ENABLE BOOL FALSE Enables the function block on rising edge. Aborts operation on falling edge. CiA405Base TIMEOUT UDINT 0 Timeout in ms; 0 means no timeout CiA405Base Output CONFIRM BOOL FALSE TRUE : function block finished without error CiA405Base ERROR CANOPEN_KERNEL_ERROR CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_NO_ERROR Error code: see CANOPEN_KERNEL_ERROR for further details CiA405Base Input DEVICE DEVICE NodeID of destination device; 0 means local device (= CANopenManager) CHANNEL USINT 1 SDO channel: 0: use any free channel; 1..n: specific channel INDEX WORD Index of object SUBINDEX BYTE SubIndex of object MODE SDO_MODE SDO_MODE.AUTO specifies the SDO Mode to be used DATA POINTER TO BYTE Pointer to memory the data should be written to. Data is written in CANopen Byte Order (= Little Endian). Inout DATALENGTH UDINT VAR_IN: Number of bytes DATA is pointing to. VAR_OUT: Amount of data bytes written to DATA Output ERRORINFO SDO_ERROR contains abort code in little endian in case of ERROR is CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_OTHER_ERROR

SDO_WRITE4 (FB) ¶ FUNCTION_BLOCK SDO_WRITE4 EXTENDS CiA405Base This function block is used for writing a specific object in object dictionary of a DEVICE . Up to 4 bytes can be written. Data is provided as an ARRAY OF BYTE . If more than 4 bytes should be written please use SDO_WRITE . If DATA was written without error CONFIRM becomes TRUE . DATA has to be in Little Endian byte order. If an error occurs ERROR becomes unequal 0. In case of a SDO abort ERROR is set to CANOPEN_KERNEL_ERROR.CANOPEN_KERNEL_OTHER_ERROR and ERRORINFO contains the associated abort code (in Little endian) as defined by CiA 301.
