Function
When there is a setting error in the
PLC Setup, the location of that error
is written to A406 in 4-digit hexadeci-
mal.
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
(A406 will be cleared when the
cause of the error is eliminated.)
Always 0000 hex.
The 3-digit binary value of these bits
indicates the cause of the Too Many
I/O Points Error.
Note These bits will be cleared
when the error is cleared.
The bit corresponding to the option
slot turns ON when an error occurs
in an Option Board (A315.13 will be
ON).
Bit 00: Option slot 1
Bit 01: Option slot 2
Turn ON when the I/O Option Board
works normally.
Turn OFF when the I/O Option Board
is in initial state or abnormity state.

A436.02: 3rd Unit
A436.03: 4th Unit

CP1W-AD041/DA041, CP1W-32ER/
32ET/32ET1, CP1W-TS002 and
CP1W-TS102 are each counted as
two Units.
Stores the number of Expansion
Units and Expansion I/O Units con-
nected as a hexadecimal number.
Note This information is valid only
when a Too Many I/O Points
error has occurred. CP1W-
AD041/DA041, CP1W-32ER/
32ET/32ET1, CP1W-TS002
and CP1W-TS102 are each
