3.1. SOE Communications Port Configuration
M
The ports on the Trusted
data collection using serial comms or via the Ethernet. The required method is chosen by first
selecting the ‘Configure Port’ option from the ‘File’ menu.
Selecting serial ports COM 1 and 2 enable the selection of Baud rate and parity.
Selection of Ethernet permits the selection of the target system IP address and port number. In almost
every case, the port number should be left at 2000.
Note that the Communications Interface must have a Modbus slave configured in the parameters for
the module in the system configuration. The disconnection timeout must be set to 300 seconds to
prevent the connection from being lost during data retrieval. In the Communications Interface Modbus
Slave window, select a Modbus Slave and check ‘Use This Slave’. The defaults will work with the SOE
collector. Refer to product description PD-8151B.

3.2. SOE Symbol File Selection
Tag, true/false state information and description text is retrieved from database files produced by the
IEC1131 TOOLSET as part of the program creation/compilation process. The Trusted
contains memory run-time addresses and state information. The file that contains the bulk of the
information is called ‘Appli.tst’ and is found in the same directory as the user’s application. For
xample, if the application is called ‘TFAT_1’, then the ‘Appli.tst’ file would be found in
e
‘C:\Trusted\Toolset\apl\TFAT_1’. Other files used by the SOE Collector include appli.dlo and appli.dco
which contain the variable dictionaries. The application must be fully compiled to generate these files.
The symbol files are made available to the SOE Collector by initiating the ‘Select Symbol File’ option
from the ‘File’ menu. Once the file has been loaded, the file path is displayed in the status banner at
the bottom of the SOE Collector window. If the application is changed and recompiled, the SOE
Collector will need to be loaded with the new copies of the files.
If the SOE collector is left running permanently as an event logger, it should be stopped whilst the
application is compiled, otherwise it will hold some of the application files open. The buffers in the
system will store the SOE events during this compilation.

3.3. SOE Target ID Selection
The Controller is allocated a Target, or Modbus Slave, ID, in the appropriate Modbus Slave
configuration in the System Configuration Tool.
In the SOE Collector, the Target ID is selected using the ‘Set ID’ option, which may be found in the
‘Target’ menu.
3.4. SOE Sort Mode
Prior to starting the collection process, the user may select the order in which SOE data is presented.
The user may select ‘Sort By Time’, or ‘Sort By Tag’ using the appropriate button on the button bar or
the menu options under ‘Sort’.
If ‘Sort By Time’ is selected, the SOE data is displayed in time order with the most recent event shown
at the top of the display.
If ‘Sort By Tag’ is selected, the SOE data is displayed in alphabetical order. In addition, groups of
events for the same tag are sorted in time order.
3.5. SOE Log File Selection
All SOE entries may optionally be logged to a log file held on the user’s Engineering Workstation. To
enable a log file, the user must select the ‘Log File’ option which may be found in the ‘Logging’ Menu.
Entries are appended to the end of the file as they are collected. There is no sorting of tag information,
even if ‘Sort By Tag’ is selected.

3.6. SOE Collection Mode
The Communications Interface has a large buffer of events. It is possible to gather this buffer first until
the collector has caught up with current events, but this can take a long time. Therefore there is an
option under the Mode menu for choosing how much of this buffer is collected.
From Now Ignore all buffered events and only collect real time events
All Buffered Gather the entire buffer first before waiting for real time events
25% of Buffer Gather the last quarter of the buffer first
50% if Buffer Gather the last half of the buffer first
75% of Buffer Gather the last three-quarters of the buffer first
3.7. SOE Start Collecting
Once the procedures detailed above have been completed, the user may start the collection process.
If any buffered events have been selected in 3.6, events currently buffered in the Trusted
Communications Interface module will be collected and added to the SOE display. Once the SOE
Collector has retrieved all buffered events, it will regularly poll for new events. All new events will be
added to the display.
To initiate the collection of SOE data, the user must select the ‘Start Collecting’ option from the ‘File’
menu
The collection of SOE data is stopped by selecting the ‘Stop Collecting’ option which is also in the ‘File’
menu.
The initial collection process can take a long time before events are displayed on the screen. The
program is parsing through events gathered before the end of the log, and it will display log entries
once the date and time of events is past the end of the current log.
If the SOE or PH collector is running when the system application is compiled in the Toolset, then the
dictionary files appli.tst, appli.dco and appli.dlo will be locked by the collector and the compilation will
fail. If it is necessary to keep the collector running during a long compilation, copy the files to another
location. Note that if the dictionary is changed in a way that affects event variables, the SOE collector
will need to be stopped to load the new symbol files.

The current display may be sent to a user selected printer using the ‘Print’ menu option from the ‘File’
menu.
4.7.3. Auto Track
Enabling this option forces the display to follow the most recent data point received. This option must
be disabled if the user wishes to zoom/scroll around the current data.
4.7.4. Zoom/Pan
Pressing the ‘+’ or ‘-‘ keys zooms the display in or out respectively. Holding the right-hand mouse
button pressed and dragging in the direction required ‘pans’ the display. Mouse-clicking on a point on
the line provides a readout window of the value at that moment (this requires the mouse point to be
precisely on the line). Left-mouse dragging a rectangle on the graph zooms the vertical axis to the
height of the rectangle.

4.9. Assigning variables for PH
Process Historian deals with analogue tags only and is intended to compliment SOE. Tags must have
the suffix ‘_PH’ at the end of the tagname and must be connected to a prochist board. A Modbus
address is not necessary.
4.9.1. PH Connection
To configure a tag for connection to Process Historian it should be configured as an output. Figure 19
shows a tag created to connect to a prochist board. The tag may be a real or integer. There is no need
to enter extended attributes. The tagname must end with _PH.
Figure 19 Analogue Output PH Tag
A prochist board must be declared within the IEC1131 TOOLSET I/O connection.
Double click on a free number in the I/O Connection. Select boards, find prochist and select OK.
This will enter a prochist board in the I/O Connection table as shown in Figure 10 above.

Once defined, the user enables process historian logging by attaching the variable created above to a
channel on this board.
Double click on the appropriate channel of the prochist board. This will display all the unconnected
output variables available for PH collection as shown in Figure 21 below.

The variable may now be attached to this channel by selecting the Connect button or by double
clicking on the tagname.
The prochist board has two parameters.
BANK Index number of the prochist board. Each prochist board should have a unique index.
DELTA Change required in each connected tag before a change is logged (i.e. event
hysteresis). This value may be in floating point.

5. SOE and Initial States
The following should be noted when using SOE data collection by any method.
• ‘Native’ output modules (P8451,61,71 etc.) never record the initial state of an output as an
SOE event.
• Non-native output modules (e.g. Regent modules) record an initial state of TRUE as an SOE
event.
• All inputs supporting SOE will always record an event if the initial input state is TRUE.
• No SOE is recorded if a variable is locked, either input or output.
• At an MP handover, Regent outputs, Peer to Peer outputs, MP complex equipment definition
board TTMRP_2 and SOE board points that are TRUE at an MP handover will generate an
SOE event.
