To read byte array from the slave
The first sub-index is 0. If only one sub-index exists, we still have to specify 0 (we cannot omit this field).
The read value is returned from the function and can be set to a variable.
Input
Slave address, SDO index, SDO sub-index.
Output
None
Return Value
Value that is read from the slave.
Declaration
public function CAN_SDO_READ_STRING(byval slaveaddress as long, byval index as long, byval subindex as long) as string
Syntax
retVal = CAN_SDO_READ_STRING(<Slave address>, <SDO index>, <SDO sub-index>)
Exceptions
Examples
Version = CAN_SDO_READ_STRING(0, 0x100a,0) ' Read device version
Print Version
