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.

tober 2000.
Item Previous specifications New specifications Relevant pages
Support for UM Area
allocation function
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).
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.
See information on UM Area
allocation in the
WS02-CXPC1-EV3
CX-Programmer Operation
Manual (W414) and the
WS02-CXPC1-E-V4
CX-Programmer Operation
Manual (W425).
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).
Item New specifications (V1 models)
EC Directives All products with model numbers ending in “-V1”
conform to EC Directives.
Model numbers “-V1” was added to the end of the model
numbers.
External appearance
The arrangement of input, output, and operation
indicators was changed.
The shape of the I/O connector was changed.
Output
specifications
Relay outputs The mechanical life of output relays was
increased from 10 to 20 million operations.
Transistor
outputs
The fuse was eliminated for both sourcing and
sinking outputs.
Terminal blocks The functional earth terminal was eliminated
(i.e., converted to an NC terminal) on CPU Units
with AC power supplies.
External dimensions The depth of CPU Units with AC power supplies
was decreased from 85 mm to 70 mm.
