The sequence counter field in the returned block is set to the last successfully processed

block 9959 from the ControlLogix processor. Compare this value to that sent by the

ControlLogix processor.

If the values match, the events can be removed from the ControlLogix processor. If the

values do not match, or the ControlLogix processor does not receive a 9959 block, the

ControlLogix processor must re-send the block.

Block 9968: Binary Input Event With CLX Time

Block identification code 9968 sends a set of binary input events with ControlLogix

processor time to the module.
