Caution

Before changing the contents of I/O memory, be sure that the changes will not
cause equipment to operate unexpectedly or dangerously. In particular, take
care when changing the status of output bits. The PC continues to refresh I/O
bits even if the PC is in PROGRAM mode, so devices connected to output points
on the CPU Board or Expansion I/O Boards may operate unexpectedly.

a) Use the Up and Down Arrow Keys to move the cursor to the left and right.

b) Use the 1 and 0 Keys to change a bit’s status to on or off. The cursor will

move one bit to the right after one of these keys is pressed.

c) Use the SHIFT+SET and SHIFT+RESET Keys to force-set or force-re-

set a bit’s status. The cursor will move one bit to the right after one of
these keys is pressed. The NOT Key will clear force-set or force-reset
status.

Note Bits in the DM Area cannot be force-set or force-reset.

4. Press the WRITE Key to write the changes in memory and return to the

binary monitor.

mal (two’s complement format).

Words SR 253 to SR 255 cannot be changed.
