Support for UM Area
allocation function
xxiv
Previous specifications
If unsupported addresses
are set in the program for
operands or for set values
for timers or counters from
the SSS during online
editing, the values will be
accepted, but a memory
error will occur in
MONITOR or RUN mode.
Communications are not
possible if unsupported
settings are made for the
peripheral port's
communications
parameters.
The following specifications have changed in products manufactured since Oc-
tober 2000.
Previous specifications
The UM Area allocation
function is not supported.
As a result, a memory error
will be displayed if the I/O
comment area is set
(although no actual
memory error has
occurred).
The following table shows the changes that have been made in product specifi-
cations beginning with the introduction of version-1 Units in May 2001 (April
2001 for some models).

New specifications
If unsupported addresses
are set in the program for
operands or for set values
for timers or counters from
the SSS during online
editing, error messages will
be displayed and the
values will not be accepted.
Communications are
possible using the following
parameters if unsupported
settings are made for the
peripheral port's
communications
parameters.
Mode: Host Link
Standard format
1 start bit
7-bit data
Even parity
2 stop bits
9,600 bps baud
Transmission delay: None

New specifications
CX-Programmer can be
used to set the I/O
comment area in the CPU
Unit, and I/O comments
can be set together with
programs.
New specifications (V1 models)
All products with model numbers ending in "-V1"
conform to EC Directives.
"-V1" was added to the end of the model
numbers.
The arrangement of input, output, and operation
indicators was changed.
The shape of the I/O connector was changed.
The mechanical life of output relays was
increased from 10 to 20 million operations.
The fuse was eliminated for both sourcing and
sinking outputs.
The functional earth terminal was eliminated
(i.e., converted to an NC terminal) on CPU Units
with AC power supplies.
The depth of CPU Units with AC power supplies
was decreased from 85 mm to 70 mm.
