RIO Block Transfer
5.
When the RIO scanner detects that the EN bit cleared, it then
clears the EW, ST and DN or ER bits, as well as the Transmitted
Word Count/Error Code. This ensures that the status bits in the
control block are not reflecting the results of the previous block
transfer operation.
Programming Examples
IMPORTANT
To prevent configuration conflicts, it is highly
recommended that each M-file buffer (My:e.x00)
should be used by only one block transfer
instruction.
