FPD(––) is executed and begins monitoring when LR 0000 goes ON. If LR 0015
does not turn ON within 123.4 s and IR 10000 through IR 10003 are all ON,
IR 10002 will be selected as the cause of the error, an FAL(06) error will be gen-
erated with an FAL number of 10, and the bit address and preset message
(“10002–1ABC”) will be displayed on the Peripheral Device.

Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
CY: ON when the time between the execution of FPD(––) and the execution
of a diagnostic output exceeds T.
