Other checks
In the PROG-VER mode, programs in the TP are checked by the
TP.
As a result, the error codes
(PEO
to PE8) shown
on
page 108 may
be displayed by the TP.
In the PARA-VER mode, parameters in the TP are checked by
the TP. As a result, the error codes (PE10 to PE18) shown
on
pages
109
and 11
0
may be displayed by the TP.
Since programs and parameters are interrelated, always be sure
to check both the parameter and the program when one
of
them
requires correcting.
When a program or parameter containing an error
is
sent
to
the
PGU, the error check is also performed by the PGU.
Its
error
codes (CE1
to
CE20) shown on pages 108 to 110 will be dis-
played by the TP.
In this case, the error detect output
BFM#3
b6 to the program-
mable controller and the error display
LED
on
the PGU panel are
also activated.
