Delta Extension Digital I/O Module, DOP-EXIO14RAE and DOP-EXIO28RAE (hereinafter
called “DOP-EXIO series”) provided for DOP-AE series HMI only. Therefore, before using
Delta Extension Digital I/O Module, the user has to open the ScrEdit (Screen Editor)
programming software, click “File” > “New” to open a new project, and select the type of
DOP-AE series HMI being used (see Fig. 1.1).

After selecting the type of DOP-AE series HMI, press OK button to complet the setting. Then,
click “Options > “Configuration” to enter into “Other” tab in Configuration option (see Fig. 1.2).
Check the box next to “Enable EXIO (Compile Ladder)” to activate the function of Delta
Extension Digital I/O Module. The user can also select the digital input and output points here
by using the drop down list right below the “Enable EXIO (Compile Ladder)” option (see Fig.
When “Enable EXIO (Compile Ladder)” option is selected, the “Ladder Editor” icon will appear
and be available for use on the toolbar (See Fig. 1.4 and 1.5). The user can click this icon and
start ladder diagram editing directly or click “Tool” > “Ladder Editor” command from the menu

Clicking the “Ladder Editor” icon can open HMI-WPLSoft editing window immediately
(see Fig. 2.1). At the same time, the window of ScrEdit (Screen Editor) will zoom out and hide
automatically. Please note that HMI-WPLSoft and ScrEdit programming software cannot be
used simultaneously. When the user is editing a ladder diagram and in the meantime the user
wants to edit a HMI program, the user must close the window of HMI-WPLSoft and then it is
possible for the user to edit a HMI program in the environment of ScrEdit programming
software successfully. There is no Open and Save option provided in the ladder diagrm editing
window. When the ladder diagrm editing window is closed, the ladder diagrm editing program

) Compiler(P)
This function is used to compile current HMI-WPLSoft programs for DOP-EXIO series
product. If the user completes the editing of the ladder diagram in the ladder diagram mode,
performing this function will check whether the ladder diagram is valid or not. If there is no
error occurred when converting the program, the ladder diagram can be converted to the
instruction program successfully; meanwhile, the program memory addresses (numbers of
steps) for each editing block will appear on the left-hand side of the start of the ladder
diagram. However, if there is any error occurred, a ladder diagram error message dialog
box will appear to display the error code and point out the exact erroneous addresses
(exact row and column where the error occurred) after the compiler action is completed.
If the user completes program editing in the instruction mode when performing this function,
the system will start to check if there is any error occurred or not. If there is no error, the
Chapter 3 Creating and Editing Programs|DOP-EXIO Series
instruction program will be converted to the ladder diagram successfully. However, if there
is any error occurred, an error message dialog box will appear to display the error code
and point out the exact erroneous steps (where the error occurred) after the compiler
action is completed.

) Search(S)
Go to(J) Ö Jump to the designated location (unit: Step). This command is used to
specify the program to jump to a designated location. If the designated step already
exists, the program will jump to this existing designated step and put it in the first line.
Method 1: Click “Search(S)” > ”Go to(J)”. Enter the designated step where the user
want to jump to, and then the ladder diagram will put this designated step
in the first line.
Method 2: Click the icon on the toolbar.
Method 3: Use keyboard shortcuts by pressing keys (Ctrl) + (J).
Search/Replace(F)
The “Search/Replace(F)” command is used to search and replace the device and
instruction within the program (if only the “Search” command is used, just enter the
device name to be searched in the dialog box). If the device or the command is found,
the view will be scrolled to the device or the command. Also, the user can search and
replace the device and instruction by specifying the type of the device and instruction.

is replaced by C100, it is then a failure.
Search Instruction
Use this command to search the specified instruction name match the search criteria in
the program. Click “Search Instruction” tab after the “Seach/Replace” function is
activated, and enter the instruction name that the user is looking for in the field of
“Search Instruction”. Then, press the “Search” button to start the search. The system
will memorize and record all the searched instruction names in the “Search Instruction”
drop-down menu. This is a useful function for the user to search more quickly and
conveniently next time.
Replace other Instruction
In “Replace other Instruction” tab, the system provides the replace criteria for SET, RST,
PLS and PLF, these four kinds of instructions and allows the user to replace the devices
match the criteria of these instructions in the program. For example, if the user wants to
replace SET M0 ~ M35 with SET Y0 ~ Y43, in order to complete the replacement, the
user can set the settings as shown as the figure below.

Chapter 3 Creating and Editing Programs|DOP-EXIO Series
Besides, as the boxes next to “Copy Comments to Replace Devices” and “Delete
Source Device Comments” are checked both, it indicates that when the device name is
replaced, the comments of the search device “M0 ~ M35” will be copied to the replace
device “Y0 ~ Y43” and the comments of the search device “M0 ~ M35” will be deleted
immediately at the same time.

$65535. Some of the internal memory addresses are “For latched”. For more introductions
and the setting range of each device, please refer to Appendix A in this manual.
When the function for DOP-EXIO series is activated, the devices for DOP-EXIO series will
appear in the “Device Type” drop-down menu shown in the “Internal Memory” selection.Some
of the devices have special definitions and will be set or referred within some specific
instructions. For more descriptions of the devices and instructions for DOP-EXIO series,
please refer to Appendixes in this manual.

The ORI instruction is used in the parallel connection of B contact. The functions are to read out the
status of present designated parallel connection contacts and perform the “ORI” operation with the
logical operation result obtained. The final result will be store in the accumulative register.
Program Example:
Ladder diagram: Instruction code: Operation:
X0
Y1
X1
LD X0 Loading in contact A of X0
ORI X1 Connecting to contact B of X1 in parallel
OUT Y1 Driving Y1 coil

Mnemonic Functions
MPS
Store the current result of the internal EXIO operations
Operand None
Explanation:
To save the content in the accumulative register into the operational result (the pointer of operational
result will plus 1).
Mnemonic Functions
MRD
Read the current result of the internal EXIO operations
Operand None
Explanation:
To read the operational result and store it into the accumulative register (the pointer of operational
result stays intact).
Mnemonic Functions
