1. According to CX-Process Tool
a. Upload/download of function block files (appended with the .ist exten-
sion)
b. This indicates reading/writing on validate action or monitor run status
windows.
By uploading/downloading by function block files (appended with the .ist
extension), ITEMs are divided into two types: ITEMs to be set as defaults
(called "default data") and ITEMs (called "operation data") that can be set
in either CX-Process Tool or SCADA software.
R: Upload by file,
(S): Initial setting data,
r: Read in the validate action window of CX-Process Tool
w: Write in the validate action window of CX-Process Tool
2. According to ITEM Setting block
This indicates reading/writing by the Constant ITEM Setting block (Block
Model 171) or the Variable ITEM Setting block (Block Model 172).
3. According to Sequence Tables or Step Ladder Program
This indicates reading/writing by the Sequence Table (Block Model 302),
Step Ladder Program (Block Model 301) or the Contact Distributor block
(Block Model 201).
4. According to HMI
This indicates sending/receiving data for the CPU Unit using the HMI.
ITEM type: Indicates the type of ITEM according to the following categories:
(For details of categories, see 3-1-1 "Configuration of Function Blocks" in this manual.)
Contact input, contact output, analog input, analog output, analog input connection information, accumulated
value input, accumulated value output, accumulated value input connection information and parameter
ITEM: Indicates the ITEM number in ascending order.
Symbol: Indicates the symbol that is indicated in CX-Process Tool.
Analog input: X, Analog output: Y, Contact input: S, Contact output: U, etc.
Data description: Indicates the name of the ITEM and its content.
Data range: Indicates the range of data that can be stored.

Each of the ITEMs in function blocks can be read and written by FINS com-
mands (command codes 0240, 0241, 0242 or 0243 Hex).
W: Download by file
(O): Operation data
Indicates the default on CX-Process Tool.
Cold start initialization: Indicates whether the content of the ITEM is initialized when a cold start is performed.
R/W mode: Indicates which of the following modes each ITEM can be read or
written by. (R: Read, W: Write, R/W: R/W-enabled)
CX-Process Tool,
ITEM Setting blocks (block models 171/172), Sequence Control
Program (block model 301/302), HMI function.
Note: On CX-Process Tool, the R/W mode is indicated by W: Download in file
units, R: Upload in file units, r: Read in the validate action window or
monitor run status window, r/w: Read/write in the validate action window
or monitor run status window, (S): Initial setting data (O): Operation data
R : Read, W: Write, R/W: R/W: enabled,
--- : R/W-disabled
Note: r and r/w: Read and read/write for validate
action or monitor run status by CX-Process
