INITIALIZE (upward)
In the PROG. mode:
The contents of the operation memory are initialized. However, the system register
(including the I/O map) and the program are not initialized. If the error of self-diag-
nostic error code 42 or lower is occured, the special internal relays R9000 to R9008
and the special data register DT90000 are not cleared.
In the RUN mode:
Operation errors, remote I/O system errors, and battery errors are cleared.
(center) The switch should normally be left in this position.
TEST
(downward)
Setting this switch to the downward position in the PROG. mode, accesses the test
mode. Switching to the RUN mode in this state, initiates test operation.
To return from the test mode to the normal operation, return this switch to the center
position in the PROG. mode.
Note
By turning on the initialize/test switch while in the PROG.mode,
you can be specify the type of operation memory to be cleared
with system register 4.
