When the execution condition is OFF, IOWR(––) is not executed. When the
execution condition is ON, IOWR(––) transfers data from the words beginning at
D to the specified Special I/O Unit’s memory. The destination information pro-
vides the node number of the Special I/O Unit and the number of words to be
written, as shown in the following diagram.

Digits 2 to 4: Number of words to write (001 to 128)

Digit 1: Node number of the Special I/O Unit (0 to F)

The control code (C) depends on the Special I/O Unit being specified. Refer to
the Unit’s Operating Manual for details.

When IR 00000 goes from OFF to ON, the following instruction writes the con-
tents of the 10 words from DM 0100 through DM 0109 to the memory area of
