DETAILED DESCRIPTION:
The SDORD command gets (reads) the value from the specified SDO on a specified device. It
can assign that value to a variable. To do this, use:
x=SDORD(slave addr, index, sub-index, length)
where:
slave addr is a variable such as: x, ab[x], aw[x], al[x], or a constant such as: 2 (a
motor with CAN address 2). The valid range is from 1 to 127. SDO’s cannot
be broadcast. If slave addr is to itself, then internal loopback is used instead.
index
is a variable such as: x, ab[x], aw[x], al[x], or a constant such as: 24640
(for object 6040hex).
sub-index
is a variable such as: x, ab[x], aw[x], al[x], or a constant such as: 0 (for
sub-index 0).
length
is a variable such as: x, ab[x], aw[x], al[x], or a constant such as: 4. This is
the number of bytes in the data; 1, 2, and 4 are the only valid values.
RSDORD(slave addr, index, sub-index, length) is the report version of the command. See
above for a description of the parameters.
The function will pause (not proceed) a user program until a confirmation is received or a
timeout occurs. In the event of a timeout, the value 0 is returned and an error code will be
