The Field Termination Unit (FTU) is the section of the I/O Module that connects all three FIUs to a single field device. The FTU primarily contains passive components necessary for front-end signal conditioning, field signal overvoltage protection, and EMI/RFI filtering. When installed in a Trusted Controller or Expander Chassis, the FTU field connector interconnects to the I/O cable assembly attached at the rear of the Chassis. The SmartSlot link is passed from the HIU to the field connections via the FTU. These signals go directly to the I/O cable assembly and maintain isolation from the I/O signals on the FTU. The SmartSlot link is the intelligent connection between Active and Standby Modules for coordination during Module replacement. The Field Interface Unit (FIU) is the section of the Module that contains the specific circuits necessary to interface to the particular types of field I/O signals. Each Module has three FIUs, one per slice. For the TMR 24 Vdc Digital Input Module, the FIU contains an individual analog to digital (A/D) converter for each of the 40 field inputs. The FIU receives isolated power from the HIU for logic. The FIU provides additional power conditioning for the operational voltages required by the FIU circuitry. An isolated 6.25 Mbit/s serial link connects each FIU to one of the HIU slices. The FIU also measures a range of onboard “housekeeping” signals that assist in monitoring the performance and operating conditions of the Module. These signals include power supply voltages, current consumption, onboard reference voltages and board temperature. Field Termination Unit (FTU) Field Interface Unit (FIU) Chapter 2 Description 14 Rockwell Automation Publication ICSTT-RM271Q-EN-P - August 2021 The HIU is the point of access to the Inter Module Bus (IMB) for the Module. It also provides power distribution and local programmable processing power. The HIU is the only section of the I/O Module to directly connect to the IMB Backplane. The HIU is common to most Trusted I/O types and has type dependent and product range common functions. Each HIU contains three independent slices, commonly referred to as A, B, and C. All interconnections between the three slices incorporate isolation to prevent any fault interaction between the slices. Each slice is considered a Fault Containment Region (FCR), as a fault on one slice has no effect on the operation of the other slices. The HIU provides the following services common to the modules in the family: • High Speed Fault Tolerant Communications with the TMR Processor via the IMB interface. • FCR Interconnect Bus between slices to vote incoming IMB data and distribute outgoing I/O Module data to the IMB. • Optically isolated serial data interface to the FIU slices. • Redundant power sharing of dual 24 Vdc chassis supply voltage and power regulation for logic power to HIU circuitry. • Magnetically isolated power to the FIU slices. • Serial data interface to the FPU for Module status LEDs. • SmartSlot link between active and standby modules for coordination during Module replacement. • Digital Signal Processing to perform local data reduction and selfdiagnostics. • Local memory resources for storing Module operation, configuration, and field I/O data. • Onboard housekeeping, which monitors reference voltages, current consumption and board temperature. The Front Panel Unit (FPU) comprises a Front Panel Termination Unit (FPTU) and a Front Panel Display Unit (FPDU). The overall FPU contains the necessary connectors, switches, logic, and LED indicators for the Front Panel. For every type of Trusted I/O Module, the FPU contains the Slice Healthy, Active/Standby and Educated indicators (LEDs), and the module removal switches. Additional bicolor LEDs provide status indication for the individual I/O signals. Serial data interfaces connect the FPU to each of the HIU slices to control the LED status indicators and monitor the module removal switches. The Module determines the contact state and line fault status by comparing the input voltage level to four user programmed thresholds and two fixed (minimum and maximum) thresholds. A "Contact Indeterminate" region is defined between the contact Closed and Open states to account for marginal Host Interface Unit (HIU) Front Panel Unit (FPU) Line Monitoring Thresholds Chapter 2 Description Rockwell Automation Publication ICSTT-RM271Q-EN-P - August 2021 15 faults in the external wiring or in the FIU. Hysteresis is provided on the thresholds by upscale and downscale values, corresponding to the thresholds for increasing and decreasing values respectively. Table 1 Example Threshold Data Tip: The channel state value returned is dependent on the previous state value. If the input level is increasing, then the lower state value will be returned. If the input level is decreasing, the higher state value will be returned. When a Module is inserted into the standby slot in a line-monitored application, then the field terminations for all the input channels are paralleled, resulting in a drop in the input voltages for the Active Module. Therefore the recommended components for line monitoring are zener Chapter 2 Description 16 Rockwell Automation Publication ICSTT-RM271Q-EN-P - August 2021 diodes, one in parallel with the field switch that is across the supply and signal, the other in series with the signal. The Module biases each input channel by means of a 5 kΩ (typical for 24 Vdc digital inputs) termination resistor to the 0 V reference of the module input circuitry. In the absence of any line fault, the zener diodes used for line monitoring purposes form a voltage divider with this termination resistor in the Module. Typically, the values are chosen so that the open contact voltage at the input terminal is about 1/3 of the field supply; with the user contact closed the voltage is about 2/3 of the field supply, illustrated in the previous threshold table, default threshold values used for non-line monitored inputs are as follows (in raw units): Default = -4096, -2305, -1971, 3046, 3072, 7168, 8192, 14848, 15872, 19456 The Input Module automatically performs local measurements of several onboard signals that can be used for detailed faul
