When using the EDS file, the Starting Speed is transmitted as a double integer value. The
parameter does not use the multi-word format outlined in Configuration Mode Data Format
reference chapter.
3.6 Buffering the I/O Data
Input and output data is transferred asynchronously to the program scan. These data tags should be buffered
with Synchronous Copy File instructions to guarantee stable input data during the program scan and guaran
-
tee that complete command data is delivered to the device.
Figure T3.9 Buffer I/O Data
When copying input data, the data can be converted from byte to integer format by specifying an integer
array as the destination for the instruction. The array must contain at least ten integer elements. The
length of the copy should be ten.
When copying output data, the data can be converted from integer to byte format by specifying an inte-
ger array as the source for the instruction. The source array must contain at least ten elements and the
length of the copy must be twenty. (The destination determines the length of the transfer, not the source.)
