In order to communicate with a specific slave we use its address and the functions CAN_SDO_READ, CAN_SDO_WRITE. CAN_SDO_WRITE sends data to the slave over a specific SDO. We have to specify the SDO's index, and its sub-index, its size, and the new value
that we would like to write to 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).

Input

Slave address, SDO index, SDO sub-index, SDO size in bits, the new value to be written.

Output

None

Return Value

Void

Declaration

public sub CAN_SDO_WRITE(byval slaveaddress as long, byval index as long, byval subindex as long,byval size_bits as long, byval new_val as long)

Syntax

call CAN_SDO_WRITE(<Slave address>, <SDO index>, <SDO sub-index>, <SDO size in bits>, <new value>)

Exceptions

Examples

call CAN_SDO_WRITE(1, 0x6040, 0, 16, 128) 'clear faults
