TrustedTM Toolset Suite T8082 2. System Configuration Manager The SYSTEM.INI file may be created manually, e.g. using ‘Notepad’, but it is best prepared with the aid of the System Configuration Manager. The facilities available via the System Configuration Manager are illustrated by Figure 4 below. Figure 4 System Configuration Manager Facilities TM SYSTEM.INI files may be uploaded to or downloaded from the Trusted TMR Processor using the System Configuration Manager.
TrustedTM Toolset Suite T8082 2.1. Accessing the System Configuration Manager The System Configuration Manager is used off-line to create/edit SYSTEM.INI files, and is accessed by selecting the Tools / isa.mnu / System Config in the Toolset program folder. The opening screen is shown in Figure 5 below. Figure 5 System Configuration Tool Opening Screen TM The opening screen shown above is used as an example only and depicts a single-chassis Trusted System housing a single TMR Processor.
TrustedTM Toolset Suite T8082 2.2. Menu Structure 2.2.1. File Menu The File menu from the opening screen allows the user to implement the following: 1. Load the Configurator text buffer with data held within a file on the Workstation. Note that the buffer is separate from the diagram (graphical representation) of the system. The user is prompted to build the diagram when loading the buffer. 2. Save the text buffer to a file on the Workstation.
TrustedTM Toolset Suite T8082 2.2.3. Communications Menu The Communications menu allows the user to configure the communications port on the Engineering Work Station (EWS) used to download the System.INI file to the TMR Processor.

The View menu allows the user to sort existing templates in alphabetical order. replicated by a button on the right-hand side of the display.
TrustedTM Toolset Suite T8082 assigned to any module, but are limited to these portable types. Enter a name for the template and a description of its purpose or effect. Select the Edit Template button on the window to design the template. appropriate to the template type. This opens an editor When all values have been entered, select the OK button. This will return to the Template Creation window. 2.3.3. Template Types There are ten types of template which may be created. 1.
TrustedTM Toolset Suite T8082 2.3.4. Threshold Templates Input modules monitor and calculate the voltage level from the field at each channel to determine the appropriate state to report to the TMR Processor. After the module has calculated the input channel voltage, a state is then determined based on the channel threshold settings. There are 8 possible states (0 to 7). An example of these state thresholds is shown in Table 1 below.
TrustedTM Toolset Suite T8082 The rules for configuring thresholds are as follows: • Each threshold must be greater than or equal to the previous threshold, i.e. T2 must be greater or equal to T1, T3 T2 etc… • The state associated with each threshold is between the threshold settings, except that the lower threshold must be higher than Tmin (in the valid OC state range), and the upper threshold must be lower than Tmax (in the valid SC state range). • Threshold values are defined as fractions of a volt.
TrustedTM Toolset Suite T8082 If no entries are made to customize the thresholds, the module sets all channels to default settings. For example, in the 8403 Digital Input Module these are as follows: default = -2304,-1971,3046,3072,7168,8192,14848,15872 The bar graph details the current voltage thresholds. These have been applied to Channel 1 of the I/O module in Figure 10 above by selecting the Set button (part of the Channel Action group of buttons).
TrustedTM Toolset Suite T8082 2. Output Modules This section defines the mapping between the output state and the front panel indicators for the specific module. The mapping defines the required operation for all output channels. An LED mapping entry is made using the syntax shown below. state# = If no entries are made in this section, the module will operate with the default LED mapping.

TrustedTM Toolset Suite T8082 3.5. Connecting I/O Channels When a board is defined, the user has to connect I/O variables to its channels. The following icons are used to represent channels in the list: .…..free channel .…..connected channel 3.5.1. Connecting variables To set the connection of a channel, double click on its location in the list on the right. It is also possible to select (highlight) it and run the Edit/Set channel/parameter command. The dialogue box shown in Figure 44 below appears.
TrustedTM Toolset Suite T8082 3.6. Directly Represented Variables Free channels are the ones which are not linked to a declared I/O variable. IEC1131 TOOLSET enables the use of directly represented variables in the source of the programs to represent a free channel. The identifier of a directly represented variable always begins with % character. Within a toolset program, the directly represented variables are listed on opening the variable dialogue to type in a variable name, as shown in Figure 45 below.
TrustedTM Toolset Suite T8082 The naming conventions of a directly represented variable for a channel of a complex equipment are listed below. s is the slot number of the equipment. b is the index of the single board within the complex equipment. c is the number of the channel. %IXs.b.c……..free channel of a boolean input board %IDs.b.c……..free channel of an integer input board %ISs.b.c……..free channel of a message input board %QXs.b.c……..free channel of a boolean output board %QDs.b.c……..
TrustedTM Toolset Suite T8082 4. TrustedTM Board Definitions Details of complex I/O equipment definitions are given in the appropriate I/O module or interface/bridge module PD. These define the data exchanged between the system and application in relation to a particular module. Each module in the system needs an entry in the I/O Connection Editor, as described in section 3 above. The definitions given in this section are for single board definitions, used for non-module related tasks. 4.1.

Decimal format for Modbus addresses The following setting in the ISA.
TrustedTM Toolset Suite T8082 download and run the application. When you change the value on-line, the value is changed in the Processor, and then the Toolset prompts you to save this change back to the Toolset. Saving this change back to the Toolset modifies the original Initial value defined in the dictionary. The changed value in the processor is retained if you ever reboot the processor, or stop and start the application.
TrustedTM Toolset Suite T8082 watchdogs on 8480 modules and the watchdog times on these modules should be adjusted. (see TN20057). Minimum scan time 32ms This is set to allow room for communications traffic and background tasks. It is especially important on some hybrid systems where legacy I/O scanning is asynchronous to main processor scanning. Scan time estimations are given in PD-8110B. Note that these tend to be pessimistic and are only estimates.
TrustedTM Toolset Suite T8082 10. Password Permissions Many different functions may be protected by a password in the Toolset. The ISaGRAF User’s Guide describes how to set these protections. The following is a list of some of the functions that may be protected. Global protection: When opening project, this is the first protection met by users preventing the project from opening. It should be set to a lower priority user password to allow all with passwords to access the project e.g. protection level 15.
TrustedTM Toolset Suite T8082 Set cycle timing: Possibility to set the project's cycle time from menu Control | Change cycle timing in TM the debugger window. (This is not recommended for live Trusted systems). Set execution mode: Possibility to set the "real time", "cycle to cycle" and "execute one cycle" modes in TM debugger window. This is in the Control menu. (Live Trusted systems should be left in “real time”). Change variable state: Possibility to modify a variable's value in Simulation mode.
