Introduction
Application - Tags, Screens, Keys and Tasks
PLC communication
3.1 Introduction
HG1X is an Operator Interface for PLCs. It communicates with a PLC
over its serial port to get the information required by the operator.
Information could be the value of a PLC register or the status of a
PLC coil. This information is displayed on the LCD display of HG1X. If
required, HG1X can also change the values of PLC registers / coils.
3.2 Application - Tags, Screens, Keys and Tasks
Microsoft Windows® based configuration software, WindMSG, helps
user to configure HG1X unit. ‘Configuration’ means making the HG1X
unit work as per the system requirements, Eg. HG1X can be
configured to be used with any PLC, display any register data,
perform any action using a key. The complete configuration for a unit
is termed as ‘Application’. Application comprises of Tag Data base,
Screens, Key Definitions, Alarms and Tasks.
Each register in the PLC memory has a unique address and can be
identified by giving a specific name to it. This information is stored as
Tag Data Base in HG1X. Any coil or register to be used in the
application must be first defined in the Tag data base.
LCD display on each unit displays the PLC data on a ‘Screen’.
Screen size varies with HG1X model. PLC data can be arranged on a
screen using different objects.
Operator can control the process by actually changing the value of
PLC registers. This is possible with the help of the keys. Different
tasks can be assigned to keys on the HG1X keypad.
Any register can be constantly monitored if alarms are defined for it.
When alarm condition is reached, the respective alarm is displayed
on the screen.
Once the application is defined, firmware for the specific unit and
PLC is downloaded and then application is downloaded into the unit.
HG1X can now communicate with a PLC.
3.3 PLC communication
HG1X can communicate with any PLC without any change in the
hardware. To communicate with a PLC, HG1X needs:
1. Communication Driver for the PLC
2. HG1X - PLC communication cable
1. Communication Driver for the PLC:
Each PLC has a defined protocol for communicating with any
device. Communication Driver is downloaded in to HG1X
alongwith the firmware. Communication driver varies from
PLC to PLC. This driver enables HG1X to talk to a PLC.
2. HG1X - PLC Communication Cable:
Proper HG1X - PLC cable is required for error free
communication with any PLC.

Application Task-List
This chapter explains in detail all the features of HG1X. We
recommend that you study this chapter before attempting to configure
and use the HG1X.
4.1 Screens
Operator can view required information on the LCD display of HG1X
unit. This information can be arranged in such a way that the operator
can very easily interpret the information received. This can be done
by using various tools. These tools are the objects. Each screen has
some properties:
Properties of Screen:
1. Password:
Access levels can be achieved by introducing a password for a
screen. Password value can vary between 0 - 9999. Unless user
enters the correct password, the screen will not be displayed. Any
screen can be password protected.
2. Associated Screens:
Associated screen can be specially useful in cases where one or
more objects are common between different screens. The common
part is extracted from all the screens, placed in a new screen and this
new screen is associated with the other screens. Any screen can be
associated to another screen.
Advantages of associated screens:
1. Saves application memory by extracting common part
between different screens and forming a new associate
screen.
2. Saves time of the application programmer.
Please note:
- Only one screen can be associated to any screen.
- No data entry object can be placed in the screen to be
accociated.
- No PLC tag embedding in the screen to be associated. To
embed a PLC tag, In Global Task-List the required PLC tag
should be copied to an internal tag. The internal tag should
be embedded in the screen to be associated.
3. Screen Keys or Local Keys:
HG1X keys have two types of definitions: Global and Local.
1. Global Definitions: Definitions remain same for all the
screens. If there is no local definition for a key for the
current screen, global definition for the key will be
executed.
2. Local Definitions: These definitions can vary with
screens. These definitions have priority over Global
definitions.
Please note that for a particular screen, a key can have local and
global definitions, local definition has priority over global and the
global definition task is not performed in this case.
Any task can also be performed by pressing two keys simultaneously.
The definition can be either local or global. The double keys function
can be very useful in HG1X models with less number of keys.
4. Screen Task-List
Tasks are operations performed by HG1X when a certain condition is
reached. Different tasks can be defined for different screens. Screen
Tasks can be assigned for three different conditions:
- Before showing
These tasks are performed before displaying a
particular screen on the display.
- While showing
Tasks are repeatedly performed while the screen is
displayed.
- After Hiding
Tasks are performed after another screen is called and
before displaying a new screen.
Example: Suppose Screen 1 is currently on the display
simultaneously performing ‘while showing’ task. Now PLC Tag calls
for Screen 2. Both the screens have all three types of tasks: Before
showing task, While showing task, After hiding task. Tasks will be
performed in following sequence:
1. After hiding task for screen 1 performed while clearing screen
no. 1.
2. Before showing task for screen 2 performed.
3. Screen 2 displayed.
4. While showing task list performed repeatedly.
5. When another screen is called after hiding task performed
while clearing screen 2.
Types of ScreenTasks:
1. Goto Screen
2. Goto Next Screen
3. Goto Previous Screen
4. Write Value to a Tag
5. Add a Constant Value to Tag
6. Subtract a Constant Value from Tag
7. Add Tag B to Tag A

1. Goto Screen:
Current Screen is replaced by the defined screen. This
command does not work when a PLC register is used as STR.
More information given in Application Task-List Section.
2. Goto Next Screen:
This task is useful when two screens are in succession.
Screen is changed to display the next screen.
If two screens
are not successive, there is a gap between two screens then
‘Screen not defined’ message will be displayed. This
message will stay on the screen till a valid screen is called.
This task does not work when a PLC tag is used as a STR.
3. Goto Previous Screen:
This task is useful when two screens are in succession.
Screen is changed to display the previous screen.
screens are not successive, there is a gap between two
screens then ‘Screen not defined’ message will be displayed.
This message will stay on the screen till a valid screen is
called.
Again this task does not work when a PLC tag is used
as a STR.
4. Write Value to a Tag:
A constant value can be downloaded to a tag using this task,
provided the tag is not a read-only tag.
5. Add a Constant Value to Tag:
A constant can be added to the current value of a tag using
this task.
6. Subtract a Constant Value from Tag:
This task is used to subtract a constant value from the current
value of a tag.
If two
7. Add Tag B to Tag A:*
Tag B can be added to tag A using this task. The result will be
stored in tag A.
8. Subtract Tag B from Tag A:*
Tag B is subtracted from tag A using this task. The result will
be stored in tag A.
9. Turn Bit On:
Any coil or bit can be turned on using this task. The bit/coil
should be a read-write coil.
10. Turn Bit Off:
Any coil or bit can be turned off using this task. The bit/coil
should be a read-write coil.
11. Copy Tag B to Tag A:*
Tag B can be copied to tag A using this task. The value of tag B
will be unchanged. Tag A will be same as tag B.
12. Swap Tag A and Tag B:*
Values of two tags can be swapped using this task. Tag A
value will be copied to tag B and tag B value will be copied to
tag A.
13. Print Data:
All the text data will be printed on the serial port.
Communication settings will be same as defined in ‘Prizm
Settings’ ‘Printer Port Options’ window. Graphical objects will
not be printed.
14. Copy Tag to STR:
A PLC tag can be copied to STR, Screen Triggering Register.
STR is a system register inside Prizm which decides the
screen to be displayed.
15. Copy Tag to LED:
LED’s on the keypad of each HG1X can be turned on/off
depending on the value of a tag. The tag should be copied to
LED register and the LEDs will display the tag value.
16. Delay:
Any task can be delayed using this task. Tags will be updated
during this delay.. After the delay is completed the next task will
be performed.
17. Wait till:
This is a conditional delay. Next task will not be performed till
the specified condition is false.
* While defining double Tag operations, make sure both the tags
have same number of bytes. Else the task may lead to erroneous
results.

* While defining double Tag operations, make sure both the tags
have same number of bytes. Else the task may lead to erroneous
results.
4.3 Alarms
Any tag can be continuously monitored by defining alarms for each bit
of that tag. To display an alarm on the screen as soon as it is
triggered, alarm object has to be placed on the screen. If the value of
the particular tag becomes nonzero, alarm is displayed in the alarm
object. An alarm is triggered for each bit in a tag. Total 256 alarms
can be defined in HG1X. HG1X stores the alarm information in an
alarm container. Maximum 64 alarms can be stored in the container.
First triggered alarm is on the top of the container. New alarm is
added from the bottom. Operator has to acknowledge each alarm by
using any key with definition ‘Acknowledge Alarm’. When alarm
condition is cleared and the alarm is acknowledged, the alarm is
deleted from the container. Alarm can also be printed on the serial
port. Printing is performed as soon as the alarm is triggered.
Two types of alarms can be defined in HG1X:
1. Consecutive Alarms
2. Discrete Alarms
1. Consecutive Alarms:
Consecutive alarms can be useful when user wants to monitor 16
consecutive tags. All the 16 consecutive tags should be defined in the
tag database. An alarm cab be defined for each bit. HG1X uploads all
16 tags in a single block. When any bit of 16 tags is found to be on
(‘1’) corresponding alarm is triggered. Triggered alarm is displayed in
the alarm object. Each alarm has to be acknowledged. User should
define a key to acknowledge alarms. User can also scroll through the
table of alarms using keys defined as ‘Next Alarm’ and ‘Previous
Alarm’. Acknowledged and inactive alarm is deleted from the
container. New alarm is added from the bottom of the container.
2. Discrete Alarms:
Discrete alarms can be useful when user wants to monitor tags which
are not in a sequence, discrete. An alarm is defined for each bit of
tag. When any bit of any tags is found to be on (‘1’) corresponding
alarm is triggered. Triggered alarm is displayed in the alarm object.
User should define a key to acknowledge alarms. User can also scroll
through the table of alarms using keys defined as ‘Next Alarm’ and
‘Previous Alarm’. Acknowledged and inactive alarm is deleted from
the container. New alarm is added from the bottom of the container.
4.4 Application Task-List
Application task-list allows user to define tasks to be performed at
power-on or while application is running i.e. Global Task.
Application task-lists are of two types:
1. Power-on tasks:
Power-on tasks are performed after HG1X unit is powered on.
These tasks are like a boot sequence for HG1X which are
performed only once. Using these tasks user can initialize some
registers, goto a particular screen after power up etc.
Please
note that user MUST define ‘Goto Screen’ Task in Power-On
task list.
2. Global tasks:
Global tasks are performed regularly till the application is in
progress. These tasks are useful when the user wants to
perform some tasks repeatedly. In case the PLC is not connected
then PLC related tasks will not be performed.
The tasks supported are as follows:
1. Goto Screen
2. Goto next screen
3. Goto previous screen
4. Write value to tag
5. Add constant value to tag
6. Subtract constant value from tag
7. Add Tag B to Tag A
8. Subtract Tag B from Tag A

5.3 WindMSG Software
HG1X unit has to be configured before its use in any system.
Complete configuration consists of defining:
- HG1X Settings
- PLC node
- Tag Database
- Screens and / or Screens Task-List.
- Keys
- Alarms
- Global and Power-on Task list
The complete configuration is stored as an Application. This
application is downloaded in HG1X.
1. HG1X Settings:
HG1X Settings define following properties of HG1X:
a. Hardware Settings
- Application Memory
Use this if only you have purchased a nonstandard
unit with a different memory option.
b. Keypad options
- Keypad Queue Size
If task for a key is in progress and another key is
pressed, then the second key (latest pressed) is
stored in a Key Queue. User can change the queue
size using this option.
- Queue full options
User has a choice to select what should be done if
the queue is full and another key is pressed. Either
the first or the last key pressed can be ignored.
c. Printer Port Options
HG1X has a Serial Printout Facility. User should connect
Serial Printer cable to the Serial Port of the HG1X.
Communication parameters for serial printing can be changed
using this option.
Please note that this does not affect PC to
unit communication while downloading firmware or
application.
- Baud Rate
Baud Rates available are 300, 600, 1200, 2400,
9600, 19200.
- Number Of Bits
Data bits can either be 7 or 8.
- Parity
Parity options are Odd, Even, None.
- Number of Columns
User can select the column size i.e. length of a line to
be printed. After the specified number of characters,
HG1X sends a terminating character.
- Terminating Character
Options for terminating character are None, CR, LF,
CR+LF.
2. HG1X Network Configuration:
This setting selects the PLC Model, PLC type, Node number in a
system. User can also connect multiple PLCs of the same type
(protocol) to a single HG1X. Each PLC must have unique identification number which is termed as NODE ID.
3. HG1X Tags:
Each register in the PLC memory has a unique address and can be
identified by giving a specific name to it. This information is stored as
Tag Data Base in WindMSG. Any coil or register to be used in the
application must be first defined in the Tag data base.
4. Screens:
Operator views the PLC data on the screen of the HG1X models.
Tasks can be defined for a screen. Also, the action for keys when a
screen is acting can be defined.
5. HG1X Global Key’s Task-List:
All the keys on the HG1X models can have user selectable
definitions. Three types of tasks can be defined for each key: ‘Press’
Task, ‘Pressed’ Task, ‘Released’ Task. Two keys can also be defined
for performing Tasks. Each key single or double can have password.
6. HG1X Alarms:
Alarms can be defined in the Alarms Window. Alarms are defined on
a single bit of any one word tag. All the tags must be defined before
defining the Alarms. Alarms can be set on two types of Tags:
Consecutive and Discrete. In consecutive type, HG1X will fetch 16
words from the PLC beginning with the defined tag. Each bit in each
of these 16 words will be an alarm bit. In discrete type tags need not
be consecutive. Again, in this type each bit of each tag is an alarm
bit.
7. HG1X Application Task-List
Application Task List is of two types: Power-on Task-List and Global
Task-List. Power-On Task-List is performed only once after the unit is
powered on. Global Task-List is performed till the unit and PLC are
communicating.

How Do I?
In this Chapter...
6.1 Frequently asked questions
This chapter answers the questions user normally asks.
1. How can I read PLC data?
To read any PLC data, the required tag should be defined in
the Tag Database. In a screen the tag should be embedded
in the required format.
2. Can I edit PLC data? How?
Any PLC register / coil can be edited except for ‘Read only’
registers / coils. Generally System registers and Input coils
are ‘Read only’. ‘Read only’ registers / coils vary from PLC to
PLC. Please refer to PLC manual for details. To edit any PLC
data define the tag in Tag Database. Place a ‘Data Entry’
object in a screen. Make sure to define the required keys.
Register and Coil data entry key definitions are given in
Table 4.1 and Table 4.2.
3. Can I keep a record of the Process data?
HG1X models can send screen data (Alphanumeric data
only) on its serial port. This output can be given to a serial
printer and a record of events can be achieved. A screen with
‘Print Data’ task can print all the alphanumeric objects.
4. Can I change screens using PLC logic?
Any PLC tag can be copied to STR, a system register internal
to HG1X, and HG1X will display the corresponding screen.
User must define the task ‘Copy tag to STR’ in Global
Application Task-List. Make sure to define screens to all the
possible values of the tag to avoid ‘Screen not defined’
message. Please note that the ‘Goto screen’, ‘Goto next
screen’ and ‘Goto previous screen’ tasks will not work in this
case. To change the screen the value of the PLC ta should
be changed.
Frequently asked questions
5. Can I perform any task continuously?
To perform any task continuously define the task in Global
Application Task-List. This task will be performed till the unit
is powered.
6. How can I ‘Hold’ any Bit on or off using a key?
To hold a bit on using a key, define ‘Turn bit on’ task in ‘Key
press task-list’ and ‘Turn bit off’ task in ‘Release key task-list’
for the same key.
7. How do I keep any screen or any key locked?
Any screen or a key can be kept secret using the ‘Password’
feature of HG1X. Password protected screen will not be
displayed till the user enters the correct password. Similarly
task for password protected key will not be performed till user
enters the correct password.
8. Can I assign scaling factor for any tag?
Value of any tag can be converted in to the required format
by performing ‘Math Operations’ on it. This DOES not change
the value of the actual tag. ‘Math Operations’ can be
performed in ‘Display HG1X / PLC Data’ objects. Data to be
written to a tag can also be manipulated by assigning ‘Math
Operations’ in ‘Data Entry’ object.
9. Can I limit the data to be entered in a tag?
Data entered in any register tag can have high and low limits.
This keeps a check on the register limits.
Refer to ‘Configuration software’ section for detailed information on
how to define an application.

Example to create Application for HG1X
Tutorial 1: Create an Application for HG1X
Model
We will create an application for HG1X-252 unit with internal tags
only. Follow the following steps:
1. Run WINDMSG.EXE.
2. After the main window is displayed, click on the New
Application icon
3. From the New application dialog box, select required unit and
click to accept the selection made.
4. As said earlier, this application is being developed with
internal tags only, hence we will not be adding any PLC in the
network. If user wants to add PLC in the network, click on the
Network Configuration icon
5. Now we have to define tags required for the application. It is a
good practice to define the tags before developing the
application. To define Tags click on Tag Database icon.
Following dialog box will be displayed. Select required
register type and register address, enter your name for the
tag.
Click on Add button to accept the tag defined. To define
a coil, change the selection Tag-type. Enter coil number, tag
name and click to accept the tag entry.

Select coil. Click to accept the task.
We want to display an alarm when bit 0 of tag D5 turns on. An alarm
object has to be placed on the screen so as to display alarm
condition. But as the space on the screen is limited we will create a
new screen, screen 2, with alarm object on it. This screen will be
triggered when the bit turns on. So in the While showing task list for
the screen no 1, a define ‘wait till’ task followed by ‘goto screen’ task.
So the screen 1 will be displayed till the alarm bit is off. Immediately
after the bit turns on the screen will change and display screen 2.
To create a new screen click on New screen icon . Enter essential
screen information. In screen 2, click on alarm object icon . Click
on the screen. Alarm object will be placed on the screen. Double click
the object to edit.
An alarm dialog box will be displayed. This window will enable user to
select text to be displayed whrn alarm is displayed. Select item from
‘Select From’ list and click . If any item is to be removed select
