Port Error
Flags
These flags indicate what kind of
error has occurred at the RS-
232C port; they are automatically
turned OFF when the RS-232C
port is restarted.
(These flags are not valid in pe-
ripheral bus mode and only bit 5
is valid in NT Link mode.)
Bits 0 and 1: Not used.
Bit 2: ON when there was a parity
error.
Bit 3: ON when there was a
framing error.
Bit 4: ON when there was an
overrun error.

A598 A59800 FPD
Teaching
Bit
Turn this bit ON to set the moni-
toring time automatically with the
teaching function.
While A59800 is ON, FPD(269)
measures how long it takes for
the diagnostic output to go ON
after the execution condition
goes ON. If the measured time
exceeds the monitoring time, the
measured time is multiplied by
1.5 and that value is stored as
the new monitoring time.
(The teaching function can be
used only when a word address
has been specified for the moni-
toring time operand.)
