150 Diagnostic display
When input has changed from OFF to ON, the
instruction records the error code indicated by (A) in
the special register, and turns ON the corresponding
annunciator relay. The error messages (max 12
characters) recorded in the register tables headed by
(B) can be monitored on the peripheral devices.

setting table ((A)+2n onwards), then decides the step
number and stores it in (B)+1.
Using the data output pattern table (A), the
instruction looks up the output pattern corresponding
to this step number and outputs it to the bit table (C).
