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
ON when an error occurs in a CP-
series Expansion Unit or Expansion
I/O Unit.
A436.00: 1st Unit
A436.10: 2nd Unit
A436.02: 3rd Unit
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/
CPM1A-TS002 and CP1W/
CPM1A-TS102 are each
counted as two Units.
If a Pulse Output Stop Error occurs
for pulse output 2, the error code is
stored.
If a Pulse Output Stop Error occurs
for pulse output 3, the error code is
stored.
Contains the Maximum Interrupt
Task Processing Time in units of
0.1 ms.
(This value is written after the inter-
rupt task with the max. processing
time is executed and cleared when
PLC operation begins.)
