If M designates the first word in a table containing a message, it cannot be one of
the last seven words in a data area.
FAL(006) and FALS(007) share FAL numbers. If two instructions use the same
FAL number, only the first instruction using the FAL number Will be recognized.
Note Refer to page 101 for general precautions on operand data areas.
Flags
ER (A50003):
N contains improper data.
Content of
*
DM word is not BCD when set for BCD.
A40215:
The FAL Instruction Flag will be turned ON when an
FAL(006) instruction is executed.
A40106:
The FALS Instruction Flag will be turned ON when an
FALS(007) instruction is executed.
A43001 to A46115:
These flags are turned ON to indicate the FAL numbers for
which FAL(006) or FALS(007) have been executed.
Example
When CIO 000000 is ON in the following example, a non-fatal error is generated
as FAL 001, the ALARM indicator on the CPU lights, A43001 turns ON, and 4101
is output to A400. Program execution will continue.
When CIO 000001 turns ON, the FAL 001 error is cleared, A43001 turns OFF,
the error code in A400 is cleared (if it is 4101), and the ALARM indicator turns off
(assuming no other errors have occurred).
When CIO 000002 turns ON, a fatal error is generated as FAL 002, the ERROR
indicator on the CPU lights, all outputs are turned OFF, and C102 is output to
A400. Program execution will stop. If a Programming Device is connected and
online, the message stored in D00100 through D00107 will also be displayed as
an error message.

Description
FPD(177) is used to monitor the execution of an instruction block according to
specified conditions, detect errors, and determine the input conditions responsi-
ble for the errors. FPD(177) is used either to monitor the time between the
execution of FPD(177) and the execution of a diagnostic output or to determine
Special Instructions
