Function
An attempt was made to refresh a
Special I/O Unit's I/O from an inter-
rupt task with IORF(097) while the
Unit's I/O is being refreshed by cyclic
I/O refreshing (duplicate refreshing).
A426.00 to A426.11 contain the Spe-
cial I/O Unit's unit number.
These bits will be cleared when the
error is cleared.
When A402.13 (the Interrupt Task
Error Flag) is ON, this flag indicates
the cause of the error. The CPU Unit
will continue operating and the ERR/
ALM indicator on the front of the
CPU Unit will flash.
This flag turns ON when an attempt
is made to refresh a Special I/O Unit
during an interrupt task while the
Unit is being refreshed in cyclic pro-
cessing.
ON when an error occurs in a built-in
analog input.

Error Flag
ON while the built-in analog I/O is
being initialized.
ON when an error occurs in a
CPM1A Expansion Unit or Expan-
sion I/O Unit.

A436.10: 2nd Unit
A436.02: 3rd Unit

A436.05: 6th Unit
A436.06: 7th Unit
Stores the number of CPM1A Expan-
sion Units and Expansion I/O Units
connected as a hexadecimal num-
ber.
Note This information is valid only
when a Too Many I/O Points
error has occurred. CPM1A-
TS002 and CPM1A-TS102
are each counted as two
Units.
If a Pulse Output Stop Error occurs
for pulse output 2, the error code is
stored.
