Page 17: Chapter 1. General Information
18 VME slots. All slots are dedicated to the control section. The power supply for the MicroNet TMR main control chassis is a separate chassis which connects to either the lower right or left of the MicroNet TMR main control chassis. The power supply chassis contains redundant power supplies.
Page 18: Specifications And Compatibility
MicroNet TMR Manual 26167V1 The MicroNet TMR control may be expanded to a multi-chassis system using the Plus8 or Plus14 chassis options. For field upgrades, the expansion racks may also be the older Simplex6 or Simplex12 chassis. Each expansion chassis has dedicated power supply, control, and I/O sections located in a single chassis.
Page 19: Chapter 2. Micronet Tmr Systems
In this case, I/O is dedicated to a specific CPU. 2.1.1—MicroNet TMR Main Chassis In the MicroNet TMR Main Chassis, whether the TMR040 or TMR5200 CPUs are used, the I/O modules are associated with a particular Kernel. If that Kernel fails, the associated I/O modules are failed.
Page 20 MicroNet TMR Manual 26167V1 2.1.3 MicroNet TMR5200 Expansion Chassis With the TMR5200 systems, connection to up to 3 Expansion chassis is accomplished through Real Time Networks (RTNs) associated with each Kernel. There are 3 RTN networks. The TMR5200 system supports the MicroNet Plus 8 or 14 chassis and MicroNet Simplex 6 or 12 chassis.
Page 21: Figure 2-1-Double Exchange And Vote Structure
Manual 26167V1 MicroNet TMR 2.1.5—TMR CPU Theory The basis of this control’s fault tolerance architecture is to detect control related faults, annunciate these faults, and allow on-line service/replacement of modules and/or transducers to correct these faults. A CPU fault tolerance logic of 3-2-0 allows the control to function normally with any CPU module failed or removed.
Page 22 MicroNet TMR Manual 26167V1 2.1.6—TMR Inputs and Outputs In a full TMR application, I/O modules are also triplicated. Each Kernel would have the same module and any expansion chassis would be triplicated. Specific TMR I/O Modules and Field Terminal Modules (FTMs) are designed for this sort of application.
Page 23: Figure 2-2-Fault Tolerant Analog Input
Manual 26167V1 MicroNet TMR Figure 2-2—Fault Tolerant Analog Input Table 2-1—AI Redundancy Manager Truth Table Discrete Input Example Each discrete input can withstand up to two failures with no loss of control functionality. If any two of a discrete input’s three “legs” fail, the control uses the third healthy leg’s sensed input signal to control with.
Page 24 MicroNet TMR Manual 26167V1 A discrete input signal is determined to be faulty when the I/O Module or I/O Channel fails or when it is determined to be different then the voted-good value used by the application. If an input is determined to be faulty, the input is removed from the control’s voting logic and an input channel alarm is issued.
Page 25: Figure 2-4-Fault Tolerant Analog Output
Manual 26167V1 MicroNet TMR Figure 2-4—Fault Tolerant Analog Output Actuator Outputs Each actuator output can withstand up to two failures with no loss of output functionality. Any leg of an output channel can drive an output’s full current signal (4–20 mA or 20–160 mA). Each CPU generates an analog output command using a Redundancy manager and known good output channels.
Page 26: Figure 2-5-Fault Tolerant Single Coil Actuator Output
MicroNet TMR Manual 26167V1 Actuator outputs are treated the same way as the other analog outputs, with the exception of a an added precision resistor in the actuator output’s return path. This resistor is used to measure and detect ground loops and coil shortages that are possible when interfacing to an actuator.
Page 27: Figure 2-6-Fault Tolerant Dual Coil Actuator Output
Manual 26167V1 MicroNet TMR Figure 2-6—Fault Tolerant Dual Coil Actuator Output Relay Outputs A six relay configuration is used to form each fault tolerant relay output. When a relay output is closed, the contacts of all six relays are closed. Because of the series-parallel configuration that the relays are in, the failure of any individual relay will not cause the output to be open.
Page 28: Figure 2-7-Fault Tolerant Discrete Output
MicroNet TMR Manual 26167V1 Latent fault detection is provided with this control to detect any relay related failure without effecting the state of the overall relay output. Each individual relay output can be configured to use or not use latent fault detection. A latent fault detection test is performed periodically or on command.
Page 29: Figure 2-8-Input Flow
Manual 26167V1 MicroNet TMR 2.1.7—Simplex Inputs and Outputs The TMR system can also use Simplex I/O modules and FTMs. Typically these are used for non-critical signals although different levels of redundant and even TMR configurations can be supported with the correct application software and the correct selection and distribution of module and signals.
Page 30: Micronet Tmr Operation
2.2—MicroNet TMR Operation 2.2.1 Theory of Operation MicroNet TMR systems are designed for 3-2-0 operation. Thus, to start a system, at least 2 CPUs must be started with the same application. If the CPUs are started individually, the first CPU will wait forever for a second CPU and 2 CPUs will wait up to 10 seconds for the 3 CPU.
Page 31: Module Replacement
Note that power must be removed from the power supply input before a module is removed or inserted. Live insertion and removal of the TMR5200 and Remote RTN modules is allowed in a MicroNet TMR or Plus chassis. These modules should be reset immediately before removing them from the RESET chassis.
Page 32: Latent Fault Detection
MicroNet TMR Manual 26167V1 2.4—Latent Fault Detection Because a TMR system can tolerate single faults, it is possible for a fault to go undetected. Undetected faults are termed latent faults. If another fault occurs when a latent fault exists, the second fault could cause a shutdown. It is important to detect a latent fault in a TMR system so that it may be repaired before another fault occurs.

TEMP_ALM_x: Temperature alarm for Kernel A, B, or C. This output is directly from a fan temperature switch which will trip at 60.0 °C. Only applicable to the MicroNet and MicroNet TMR chassis. A_FAULT: The CPU A Fault Boolean will be set true when CPU A is not in sync.
