I:000/17: When you set this instruction to the true state, the next
instruction, a one-shot block transfer write, sends data to the scanner.
The Move instruction then initializes the first word of the data file that
is used by the block transfer read instruction in the next rung.
Instruction BT20:2.DN: This instruction will be true when the block
transfer write has completed. The compare instruction that follows
compares the first word of data sent from the scanner to the first word
of data you send to the scanner. When the messaging function has
completed, these two words will be equal.
Instruction BT20:3.EN: Any time the block transfer read is not
enabled, this instruction causes the block transfer read to be enabled
if the two earlier conditions are true.
BTR: Reads 64 words of data from the scanner.
The following table displays data sent to and received from the
scanner. Values are in hexadecimal.
