Instance smarts

Posts: 11
If Instance smarts don’t change from DA/AE view, then smart should be updated.

Changing Serve/Client Evaluator

Posts: 11
1-When changing Server/Client Evaluator, rebuild evaluator should be used. In this case if there is any problem, all related files should be omitted and repeat the process again.

2--Instead of using Server Evaluator, Client Evaluator must be utilized.

Quality=Bad waiting for Initial data

Posts: 11
If Quality= bad waiting for initial data, Node definition and all connection for node configuration must be checked.

DiscreteColor/Contious Color Dynamic

Posts: 11
It’s not admissible to use more than one dynamic of DiscreteColor/ContiniousColor in one object.In case of necessity, the dynamic source should be transform to evaluator.

Switch dynamic

Posts: 11
1-For using Push+Toggle in Switch dynamic it is so important to remember that, this dynamic is effective on Shape or two sates symbols. For example a simple rectangle cannot be used with Toggle state of Switch dynamic, In this case, it would be better to use Button shape or Radio Button or ChechBox, if not two shapes or two symbols should be grouped and used.

2-When using Switch dynamic , then Focus=true.

Using some dynamics at the same time

Posts: 11
Utilizing some dynamics at the same time cause them to be ineffective. Such as Change Color dynamics, changing Size or Location dynamics with Deactivator.
Deactivator dynamic have three states: Freeze, Hide, Disable. If we use Deactivator dynamic at the same time with the dynamics which are more significant in their other properties , it causes fault in control system.

Dynamics with the same application

Posts: 11
Utilizing the dynamics which have the same application such as:
· Switch +Text writer
· Switch + Slider or Dialer
· Dialer + Slider
· Selector +Animator

In the first three cases which results “write” action, utilizing of the two dynamics at the same time results applying “write” in two sources at the same time.
In the last case it can be seen in the example that although there is one specific quantity for dynamicsources there are 3 different results.

Usage of Dynamic on some properties

Posts: 11
Using the dynamics which are effective on the properties such as enable/disable, Pen, Brush… is not recommended.

In this figure you can see the difference of using two dynamics: DiscrereColor and AlarmThe Gray Valve indicates state of Closed Valve. In this case if we use Alarm dynamic and the Alarm happens, it will be applied on the settings of the symbol. So it would be better if we use different symbol to show alarm.

In the above figure you can distinguish the status of the closed valve and being in the alarm state.
Also there are some cases which are recommended not to apply at the same time:
· Discrete Color and Continuous Color with Alarm dynamic
· Quality with Deactivator

Using Invoke Method

Posts: 11
If a user apply a script which is running, such as updating a table in a datagridview, he should be ensured that the intended method is also running in the main thread, this means usage of the Invoke method.
For Example:

For the other applications such as updating charts and so on this method is applicable.

1. Why choosing HPI?

is a fully scalable, powerful, easy to configure, web-enabled HMI/SCADA (Human Machine Interface / Supervisory Control and Data Acquisition) software for industrial automation and it is fully portable and independent of the control system.

2. What kind of project can HPI be used for?

It is possible to use HPI for a small project as a single station project or use it for a very large project with several servers and clients as a multi station project.

3. Is it possible to use HPI for a very large project?

Yes, it is possible to use it for a very large project with several servers and clients as a multi station project.

4. What is HPIDesign mode?

HPIDesign provides an interface for designing projects, graphic pages, reports, alarms and server configurations.

5. What is HPIRun mode?

HPIRun is used for running the designed project and monitoring the production line and generating reports.

6. Is it possible to use OPC servers in other pc stations?

Location of OPC servers in network doesn’t affect project type. This means a standalone project can use OPC servers in other PC stations.

7. What is Engineering work station (ES)?

This is a station for the engineers to design project using HPIDesign and PCE applications.

8. What is Operator work station (OS)?

This station is used for running the designed project using HPIRun.

9. What is Historical Data Warehouse (HDW)?

This package is designed for providing features for backup, archive and deleting project run-time data.

10. What is the role of Project Server (PS)?

This is a server which provides services for maintaining the design source of the project and delivers a multi-engineering environment. Each project can have one Project server.

11. What is DXS Information server (DIS)?

This server collects data from the available devices and delivers them for monitoring in HPIRun. Each project can have several DISs and each DIS can have one redundant. DIS is the most essential part of HPI application. It acquires information from production line and other sources and provides it for HPI clients.

12. How many ES can a project have?

Each project can have unlimited number of engineer work stations. In the case of having more than one ES, Project server component is necessary.

13. Is it possible to have more than one OS for each project?

Each project can have unlimited number of operator work stations.

14. Is it possible to have two HDW for one project?

Each project can have one Historical Data Warehouse.

15. Is it possible to Save/Copy projects while HPI Run mode is running?

No, first it should be stop and Save/Copy in HPIDesign mode then run.

16. What is the minimum free space for installing and running HPI?

The hard disk on which HPI is installed needs at least 300 MB of free space, but for each project on the machine you may need additional free space for run time data logged by the server as well as the configuration data of the project on the hard drive which you have created the project. The amount of free space needed is completely related to the number of alarms and data logged by the system on every day work. In addition you always need to watch the disk free space to avoid data loss.

17. Which soft wares are required for reporting?

Because the HPI reporting is based on Microsoft Excel 2007, to design and get reports on HPI data you need this software installed on your PC. If you don‘t want to use basic reports of HPI, then you don‘t need this software.

18. How can I activate the trial version of HPI?

There are two activation methods available: activation over the Internet and activation using a license file.
To activate your version of software over the Internet, select the appropriate option in Activation Wizard dialog and click on Next button. In the next dialog enter the activation key provided with the CD-ROM of the product and select Next. Now wait until the wizard obtains a license from the license server.

19. What kinds of Scripts can be used in HPI?

There are three types of scripts available in HPI:
· Server scripts: This type of scripts will run on DIS server.
· Script modules: Script modules are containers of all functions, variables, classes, etc. which will be used all over the project.
· Graphic page script: Each graphic page can have a script file which will run on an HPI client when the graphic page opens on that client.

20. Can I change the programming language of a script?

You cannot change the programming language of a script after creation unless you remove and then recreate it.

21. What kinds of names are acceptable for nodes?

Only English characters, numbers and “_” are acceptable on names. Name should start with a character.
