Item/point names, corresponding to Input/Output register area CIO, may be without
prefix.
(*) Value range for unsigned integer is from 0 to 65535 (item/point name with suffix "U"
("u") or without suffix), for signed integers from 32768 to 32767 (item/point name with
suffix "S" ("s")) and for 16-bit BCD is from 0 to 9999. The value range for 32-bit integer is
from -2147483648 to 2147483647 and for 32-bit BCD is from 0 to 99999999. Default
value range for Integer Tag Type is unsigned integer.
(**) Read only. Note: with DR area item without suffix (or with suffixes u, s, b) are
Read/Write.
(***) Represented memory area ranges are for CV1000, CV2000 and CVM1-CPU11-E
(except Transition Area and Step Area Flag status) type controllers. For models CV500
and CVM1-CPU01-E (except Transition Area and Step Area Flag status) - accessible
memory area ranges are 0:00...511:15 for Discrete items and 0...511 - for Integer items.
Transition Area TN and Step Area Flag status area ST are not supported on CVM1 PLCs.
(****) Represented memory area ranges are for CV1000, CV2000 and CVM1-CPU11-E
type controllers. For models CV500 and CVM1-CPU01-E - accessible memory area
ranges are 0...8191.
(*****) Represented memory area ranges are for CV1000 and CV2000 type controllers
only. For model CV500 - accessible memory area ranges are 0...1023. With other CV-
series PLCs – not supported.
Expansion area Current bank as well as Expansion areas (from EA to EH) is relevant only
with CV1000 and CV2000 PLCs.
Item names IR and DR are valid with following Omron PLC models: CV1000, CV2000
and CVM1-CPU11-E.
The configuration of the discrete data can be as follows:
Flag or Bit Status 0: Bit is OFF;
1: Bit is ON;
Step Status 0: INACTIVE;
1: HALT;
2: PAUSE;
3: EXECUTE;
The following examples show the correct format for item names for CV-series PLCs:
CIO1:15 - CIO area (Bit status), word address 1, bit number 15.
211 - CIO area (Word contents), word address 211
TN200 - Transition Area flag, address 200
ST0007 - Step Area Flag status, address 7
AC6 - Action Area Flag status, address 6
D3F - real (floating point) item, value is taken from words D3 and D4.
