The INFO system
is a summary of information that can be viewed in the running application in the special window. The INFO system is provided for designers and it allows them to find the current state of the system, states of its parts including diagnostics and statistics. For example it is possible to find all data values in the application, to get the statistics of the success rate of the data transfer via the computer's serial port, display debug texts written in scripts into the Debug item of the INFO system
, and many others informations.
INFO system can be configured in the PmaRoot
How to open the INFO system
the INFO system window can be opened:
- from the predefined tool bar.
- by Ctrl-I
keypress (see Example
In the development environment
the INFO system window can be opened:
- from the tool bar
In the Web browser
, the INFO system can be opened if the PROMOTIC application acts as Web server
and if in the application is the PmaWebInfo
The INFO system window consists of three parts. On the left there is a tree of individual pieces of information (of items). In between there are page windows from which it is possible to view chosen information (most information have more parts and that's why they are divided into pages). On the right there is a set of control buttons:
- Open new
Opens new INFO system window. This way it is possible to open up to 3 more windows (maximum number of open windows is 4). It is possible to observe several different indicators simultaneously.
- Refresh: Refreshes window content. It is also possible to activate autorefresh by the "Start" button instead.
- Print to file
Saves the page content into a text file. The filename entry window is opened before saving (the file is preset according to the "File to print the content
" configurator). It is also possible to define whether to save only the selected page or all pages of the corresponding item. See also the Pm.InfoWriteToFile
In some INFO system pages some actions can be executed. These actions can be initiated by this button or by the right mouse button (local menu) in corresponding page. This can be done only if the "PmaRoot > Permissions > InfoEdit
" permission is fullfiled. The action can be performed over the information also by the Pm.InfoAction
- It is possible to delete all records over the Debug_info items.
- It is possible even to enter new value
over the information about the PmaData
- Syntax of displayed numeric value
: Here, it is possible to define the syntax of numeric values:
- Binary: Display as binary
- Octal: Display as octal
- Decimal: (default) Cisplay as decimal
- Hexa: Display as hexadecimal
- Bits: Display as bits
Starts / stops value autorefresh.
- Period (s): Autorefresh period (in seconds).
The INFO system remembers its state
(position and size of the window, last opened page, width of columns, refreshing period) and when opening the window, the last state is set. But this state is stored only in the memory by default and so it isn't preserved when closing the PROMOTIC system.
The state of the INFO system can be stored even in the application INI file. It is performed by setting the StoreType key in the section [InfoSystem] - see Description of keys in the [InfoSystem] section.
The item list of the left window follows:
Probably the most important information are global application errors
item). If the application runs and for example a division by zero occurs, then the system doesn't break down of course but it is an error that is written into the INFO system. The designer can come to the application after some days, watch the INFO system, find out the errors that occurred and make an update of the application accordingly. Errors
item is divided into several pages:
list of all errors
- Panel: detailed list of panels errors
detailed list of scripts errors (including qualification of events, row and column numbers)
- Comm: detailed list of communication errors
The print-out of global errors can also be done into the Debug item of the INFO system in parallel. It is performed by setting the "ErrRedir" key in the application INI file.
In the Warnings
item, there is only one page so far, named Obsolete
. On this page, the obsolete components
used in the application are being displayed. Some of these obsolete components may not be functional in further PROMOTIC versions. The designer can transfer these obsolete components into new concepts.
See: Description of the "Warnings" item in the INFO system..
The PROMOTIC system itself takes care about writing into most items. But the item Debug_info
exists and it contains "Debug1
" and "Debug2
" pages. The designer can write into them. It is done by the Pm.Debug
method. The text in the parameter of this method is added as a new line into the relevant page. The designer can watch in a simple way how the watched process runs.
The number of rows in "Debug1" and "Debug2" pages is limited (default 1000 rows). If this limit is reached, then the oldest line is deleted. This limit can be set in the "Maximum number of rows in the "Debug_info" item" configurator.
It can be set the "EnableDebug" key in the Application.ini file in the [Log] section so that writing into Debug_info is done into the LOG file in parallel.
In this part some global system information can be found. SYSTEM
item is divided into several pages:
: Several global information regarding the application, for example the PROMOTIC version (See also: How to find PROMOTIC version
), OS Windows
version, running time, application folder, local IP address, etc.
Complete application statistics. Displayed information:
- number of running scripts and number of script errors
- number of opened panels
- number of changes in alarms
- number of saved trends
- number of correct and incorrect communication transfers
From this item it is possible to find out the information (statics, current values, settings, etc.) about the communication with external sources. Here is for example:
page offers the information regarding the network licenses PmaData(Web)Client
. This information is also available by the Pm.LicenceInfo
- The Connected_Users
page offers the information regarding connected network users
- The information about the state of the PROMOTIC communication drivers
. There is a list of the communication drivers used (PmaComm
objects) each with the information pages:
- Statistic: Transfer statistics, for example the number of valid transfers, invalid transfers of certain types, etc.
- State: The current state of the driver, for example processing state, transfer parameters, etc.
The contents of transferred data and completed actions. It is a detailed transfer history using a cyclic line list. Each line contains either the character (in decimal, hexadecimal or ASCII form) or the completed action with parameter.
- Log: This page is included only in specific communications displaying the event history digestedly but in less detail compared to the "Monitor" page.
item provides the information regarding the status of the Web communication
(the HTTP trasmission statistics, the contents of last transmissions, etc.). This item can be found in the INFO system only if the PmaWeb
object is present in the application.
- The DDE
item provides the information regarding the status of the DDE communication
. This item can be found in the INFO system only if the "DDE enabled
" configurator is checked.
The designer can observe the current state of any Pma
object in this item. For example, he can watch current values in the PmaData
object, how many times the event is triggered in any object, etc.
The PmaRoot item is displayed in the INFO system window only in runtime (only if the "PmaRoot > Permissions > InfoShowApp" permission is fullfiled).
If the "PmaRoot > Permissions > InfoEdit" permission is fullfiled, then some object have the "Actions" button active, where it is possible to change the properties (e.g. in the PmaData object change the Value property of the variables) or call methods (e.g. in the PmaCommGroup object call the Refresh method).
