Preface
Thank you for purchasing H0U-XP programmable controller developed and produced by
Inovance! H0U-XP programmable controller (hereinafter referred to as H0U-XP) includes two
programming parts: logic (PLC) and text (TOD). The logic (PLC) programming software is
AutoShop software, and the text (TOD) programming software is HTodEditor software. Both are
developed and issued by Inovance. The user can realize the logic (PLC) or text (TOD) program
control of H0U-XP by using the corresponding programming software.
You are welcome to visit Inovance's official website http://www.inovance.com and download
AutoShop, HTodEditor software and the latest version of this manual.
[Note]: Except for "1 Programming Software and Installation" which involves the introduction of
logic (PLC) programming software AutoShop, the rest of the chapters are mainly introductions to
the use of text (TOD) programming software HTodEditor.

2.1 Structure layout of page editing software
A project is developed based on pages. Each page completes some specific functions and can
switch over to any other pages.
After opening the project, the user can create or open a page. Elements such as text, indicator
lights, switches, data display setting windows, and jump keys can be placed on each page. The
pages can switchover, and the operator can complete data monitoring, parameter setting, switch
control, alarm list monitoring and other operations.
The structure layout of the HTodEditor software after opening is shown in the figure below.
Page editing area: a snap grid is displayed in the display area. The distance between the top,
bottom, left, and right of the black dots is 16 pixels, and the entire page is a 192×64 pixels matrix.
When the designer places or moves the controls, he refers to the location of the adjacent dots to
facilitate the alignment of the controls. When the designer uses the mouse to drag the control to
move, the distance of each movement is an integer multiple of 4 pixels.

3.2 Display parameters
Parameter type
Parameter description
Start page
Used to define the page displayed after power-on, generally used to
display the welcome page.
Default page
Used to set the default display page. When the ESC button has no
special function, press the ESC button to jump to the default page.
Alarm page
After defining this page, once there is an alarm message, it will
automatically jump to this page. Related to the alarm list, the alarm list
definition variable will jump to this page when an alarm occurs. If the
alarm page has been edited, it will jump to this page when an alarm
occurs. If the alarm page is 65535, jumps to the default alarm page when
an alarm occurs.
Note: If the set alarm page has not been edited, it will also jump to the
default alarm page when an alarm occurs.
Password level
This software defines the highest level 4 password.
Screen saver
It is used to set the time of no key operation and the screen saver page.
After this time, it will automatically jump to the screen saver page.
Turn off the
backlight
It is used to turn off the LCD backlight after the time of no key operation.
Auto alarm page
Used to define whether to jump to the alarm page when an alarm sign
appears. For the definition of alarm sign, see "3.1 Parameter Setting-
".
1) Page control
The page control function is to associate the interface number of the text with the data register of
the PLC. If you need this function, you first need to check the relevant options of status control,
and then set the D component address related to the text. Take D0 as the associated variable as
an example, as shown in the figure below:
2) Multi-language support
At present, the H0U integrated programmable controller only supports two languages, Chinese
and English. Set the switch between Chinese and English by storing language register under
parameter setting. When the storage language register is set to 0 text, the content of Language 1
When the D0 component
data of the PLC changes, the
page of the text also changes
to the page indicated by D0.
When the text page changes,
the D1 element of the PLC
will be converted into page
number data accordingly

is displayed; when the storage language register is set to non-zero text, the content of Language
2 is displayed.
3) Report password level
If the Report password level option is checked, the current password level will be displayed in the
associated PLC register. (this software defines the highest level 4 password)
4) Register setting control
If you check to allow register setting control, when the value of the lower eight bits of this register
and the "setting control value" of a certain register are more than 0, the register is in a settable
state. For details, see the section "4.4 Registers" below.
▪Page attributes
▪First enter the editing state of the initial page of the system (the default page is 1). The lower left
corner of the interface is the attributes of the current editing page (page 1), each page has
attributes, as shown in the following figure.
Page description
Describe the nature of the page, which is convenient for the designer to
manage. It only serves as a reminder and can be omitted. For example,
enter “Main Menu”.
Press Up key to
page
After setting a specific page number, press the up key [▲] on the current
page of the display, and the display will jump to the page pointed to by the
page number.
Press down key
to the page
After setting a specific page number, press the up key [▼] on the current
page of the display, and the display will jump to the page pointed to by the
page number.
When the display is running, pressing [ESC] key, [▲] key or [▼] key is the simplest way to switch
pages. In addition, the page jump can also be realized by setting the function keys.
Note:
▪If the [▲] key or [▼] key of the current page is set as a function key, the page jump
parameter in this page has no effect.
▪If the page specified by the [▲] key or [▼] key does not exist, the actual jump page number
will be extended upwards or downwards in sequence until it reaches 0.
▪If the page contains data setting controls, during the data setting process, the [▲] key or [▼]
key performs the value increase and decrease functions. After exiting the value setting state,
the [▲] key or [▼] key recover the page jump function.
