Description The Trusted TMR expander processor module resides in the processor slots of the Trusted expander chassis and provides the slave interface between the expansion bus and the expander chassis backplane. The expander bus allows multiple chassis systems to be implemented using UTP cable connections whilst maintaining the fault tolerant, high bandwidth inter-module bus (IMB) capabilities. The module provides fault containment for the expander bus, the module itself and the expander chassis, ensuring that the effects of these potential faults are localized and system availability maximized. The module is fault tolerant with Hardware Implemented Fault Tolerant (HIFT), Triple Modular Redundant (TMR) architecture. Comprehensive diagnostics, monitoring and testing provide rapid fault identification. Hot standby and module sparing configurations are supported, allowing automatic and manual repair strategies. Communication between the expander processor and the TMR processor is via the TMR expander interface module and the triplicated expander bus. The expander bus is triplicated, point-to-point architecture. Each channel of the expander bus comprises separate command and response media. Voting is provided at the expander bus interface to ensure that cable faults are tolerated, and the remainder of the expander processor operates in a fully triplicated mode, even in case of cable faults occurring. Communication between the expander processor and the I/O modules in the expander chassis is via the IMB on the backplane of the expander chassis. The IMB is identical to that within the controller chassis, providing the same fault tolerant, high bandwidth communications between the interface modules and the TMR processor. As with the expander bus interface all transactions are voted, localizing faults to Fault Containment Region (FCR) within the IMB should occur. The TMR expander processor module derives its internal voltages from dual redundant +24V dc power supplied via the module connector from the Trusted expander chassis backplane. Each FCR derives the required supplies independently. Non-critical monitoring and module status display functions (front panel LEDs) are also provided. Features Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation. Hardware Implemented Fault Tolerant (HIFT) architecture. Dedicated hardware and software test regimes which provide fast fault recognition and response times. Automatic fault handling without nuisance alarming. Hot replacement. Front panel status LEDs.

Description The Trusted TMR 24V dc digital input module interfaces to 40 field input devices. A wide input voltage range and programmable thresholds allow the module to be used in current source and current sink configurations. Comprehensive diagnostic tests are performed on each input channel, including tests for stuck on and stuck off failures. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 input channels. When a line-monitoring device is installed at the field switch, the module can detect open and shorted field cables. Line monitoring can be independently configured for each input channel. The module provides on-board sequence of events (SOE) reporting with a resolution of 1ms. A change of state triggers an SOE entry. States are determined by programmable voltage thresholds that can be configured on a per channel basis. When the field voltage and field return are connected to the auxiliary input channels of the module, thresholds can be specified as a ratio of the current field supply voltage. Each triplicated section of the module, referred to as a slice, conditions and measures each channel independently. Each slice is optically isolated up to 2500V dc. Each slice sends its data to a safety layer hardware voter that presents the information from all three slices to the Trusted TMR processor. When a fault is detected on a slice of the module, the Trusted TMR processor will flag the error, indicating the need to replace the module. The Trusted TMR processor will continue to use the information provided by the remaining two slices until a replacement module is available. Replacement modules can be located in a standby slot next to the module or in a designated SmartSlot with a temporary connection to the same Trusted termination assembly. Modules may be placed in any I/O module slot in a Trusted processor chassis or expander chassis. Once the I/O module configuration is set, mechanical keying is available on all I/O modules to prevent inserting a module into an incorrect slot. Configuration of the module is carried out using the Trusted Toolset running on an engineering workstation. Once configured and loaded into the Trusted controller, replacement modules are online educated by the TMR processor. Features 40 TMR input channels per module. Comprehensive diagnostics and self-test. Line monitoring on a per channel basis. 2500V dc optically isolation. On-board 1ms resolution sequence of events reporting. Hot replaceable. Front panel status LEDs for each channel. Module fault and status indicators. IEC 61508, SIL 3 safety applications.
Description The Trusted TMR analogue input module interfaces to 40 single-ended field input devices. A wide input range and programmable thresholds allow the module to be used in most voltage or current configurations. Comprehensive diagnostic tests are performed on each input channel, including tests for out of range values and stuck at failures. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 input channels. The module can apply a digital filter to each input channel. Individual channels can be configured for high noise immunity (50Hz or 60Hz rejection), low noise immunity (fast response) or pass-through operation (no filtering). Each input channel has four configurable state thresholds, which may be assigned to SOE reporting. A change of state triggers an SOE entry. The on-board sequence of events (SOE) reporting has a resolution of 1ms. Each triplicated section of the module, referred to as a slice, conditions and measures each channel independently.

Description The Trusted TMR 24V dc digital output module interfaces to 40 field output devices. Outputs are arranged in five groups of eight outputs. All outputs in a group share a common power source and return. Fault tolerance is achieved through Triple Modular Redundancy (TMR) within the same module for each of the 40 output channels. The module provides on-board sequence of events (SOE) reporting with a resolution of 1ms. The event is the actual sensing of the field device loop current. Each triplicated section (slice) of the module, receives output data from the Trusted TMR processor and sends its data to an internal safety layer hardware voter. Each slice uses the voted data to control the outputs. Every output channel consists of a six-element voted array. The output switch array provides fault tolerant, uninterrupted control under an output switch failure condition. Output switching and fault diagnostics comply with the demanding requirements of IEC-61508 SIL-3 for First fault - Fault tolerant, and Second fault Fail-safe outputs. When a module fault is detected, the Trusted TMR processor will flag the unhealthy condition, indicating the need to replace the module. Control continues until a replacement (healthy) module is available. Replacement modules can be located in a standby slot next to the module or in a designated SmartSlot with a temporary connection to the same Trusted termination assembly. Each output is user configurable to perform line monitoring of the connected field devices to detect field wiring and load failures. Automatic over-current protection is inherent in every output circuit which eliminates the need for fuses. Modules may be placed in any I/O module slot in a Trusted processor chassis or expander chassis. Once the I/O module configuration is set, mechanical keying is available on all I/O modules to prevent inserting a module into an incorrect slot. Configuration of the module is carried out using the Trusted Toolset running on an engineering workstation. Once configured and loaded into the Trusted controller, replacement modules are online educated by the TMR processor. Features 40 TMR output channels per module.
