N
1 to 511 #0000 to #FFFF
(These FAL num-
bers are shared

with FALS num-
bers.)
*Other settings would be constants #0200 through #FFFE or a word address.
Generating Non-fatal System Errors
The following table shows the function of the operands.
Note The value of operand N must be the same as the content of A529
(the system-generated FAL/FALS number).
Operand
N 1 to 511 (These FAL numbers are shared with FALS numbers.)
S Error code that will be generated. (See Description below.)
S+1 Error details code that will be generated. (See Description below.)

The operation of FAL(006) depends on the value of N. Set N to 0000 to clear
an error and set N to 0001 to 01FF to generate an error. A system error will be
generated if the value of N equals the content of A529.
Generating Non-fatal User-defined Errors
When FAL(006) is executed with N set to an FAL number (&1 to &511) that is
not equal to the content of A529 (the system-generated FAL/FALS number), a
non-fatal error will be generated with that FAL number and the following pro-
cessing will be performed:
1. The FAL Error Flag (A402.15) will be turned ON. (PLC operation will con-
tinue.)
S
Generates a non-fatal error with the corre-
sponding FAL number (no message).
Generates a non-fatal error with the corre-
sponding FAL number.
The 16-character ASCII message contained in
S through S+7 will be displayed on the CX-
Programmer.
