Chapter 1 Detail Drive Configuration and Operation
Datalink Programming
Datalinks are transmitted and received through block transfers. The SLC/PLC-5
is limited to 16 bit integers and floating point. Because the SLC/PLC-5 does not
support 32-bit integers, 32-bit integer Datalinks remain split into two, 16 bit
integers. In order to send or receive floating-point Datalinks we have to swap the
LSW and MSW and utilize the COP (copy) instruction. The following examples
are for transmitting and receiving the floating-point Datalinks, but do not show
the logic for the block transfer I/O messages. See Chapter 4 of the 20-COMM-R
User Manual for an example program for the block transfer I/O messages.

Convert the speed feedback that comes over RIO as 2, 16 bit intergers into a 32 bit floating feedback.
N11:10 = LSW of speed feedback from RIO (counts)
N11:111 = MSW of speed feedback from RIO (counts)
F12:2 = 32 bit floating point speed feedback (counts)
