Item/point names, corresponding to IR and SR areas, 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
(***) Addresses 50 to 199 in IR & SR area in CPM2A/CPM2C PLCs and 20 to 199 in IR &
SR area in CPM1/CPM1A/SRM1(-V2) PLCs are read only.
(****) Addresses DM1024 to DM6143 in CPM1/CPM1A PCs and DM2048 to DM6143 in
CPM2A/CPM2C/SRM1(-V2) PCs are read only.
The following examples show the correct format for item names for C/CPM2x PLCs:
IR2:01 - CIO area (Bit status), word address 2, bit number 1.
211 - CIO area (Word contents), word address 211.
LR62.10 - Latching Relay area (Bit status), word address 62, bit number 10.
DM21 - Data Memory area (Word contents), word address 21.
