1 Overview The Industrial Remote Interface Unit (IRIU) I/O device provides a signal conversion and manipulation interface between sensors and effectors. The IRIU utilizes an embedded micro-controller that runs factory-loaded software specific to its application and a round-robin scheduler that does not require an operating system. It can be mounted on plant equipment in harsh environments and communicates within a system through an Ethernet connection. The module’s highly flexible and rugged design suits a diverse range of applications, such as wind turbines, gas and steam turbines, and combined-cycle power plants.

The IRIU performs the following functions:

• Reads data from analog and digital sensors

• Performs required signal processing and conditioning

• Generates the analog and digital signals for effectors

• Communicates with the system controller

• Reads and applies the system configurable parameters required by the application

IRIU I/O Device

The IS421IRIUH1A is the only IRIU version currently available and supports Simplex configuration only.

The IRIU can be configured using the ToolboxST* application. It is integrated with ControlST* Software

Suite V07.07.00C and later but may be used with earlier versions upon download of the GSDML. Refer

to the chapter Configuration for IRIU configuration details for each I/O type.

Note: For additional information, refer to the following documents:

4.3 Protection Functions The IRIU does not provide any protection or safety mechanisms.

4.4 Power-off and Restart Logic On application of power to the IRIU, all driven outputs are held in a de-energized state while it performs the following actions;

• Perform a set of tests to determine its operational integrity. o On failure the IRIU performs a restart to attempt a recovery. o On successful completion of the tests the IRIU continues.

• Await initialization and parameterization from the controller. Once initialized the IRIU proceeds with normal operation until the IRIU is;

• disconnected from the controller; when it will return to an initialization state waiting for reconnection to the controller; all driven outputs are held in a de-energized state.

• A manual shutdown occurs when instrument power to the IRIU is removed; all driven outputs are held in a de-energized state.

• A global fault is detected (which affect the operational integrity of the IRIU) the IRIU will first restart to attempt a recovery.

4.5 Failure Analysis Probability Reliability parameters are calculated using MIL-HDBK-217 FN2 Parts Count models and the appropriate

failure rates from the IRIU failure modes and effects.

5 Configuration

5.1 ToolboxST Configuration and Parameters

An Embedded PROFINET Gateway (Embedded PPNG) module or PPNG PROFINET Gateway

Module is required to interface to the IRIU for use as part of a Mark VIe control system.

The IRIU supports a simplex Line PROFINET topology.

For more information, refer to the Mark VIe and Mark VIeS Control Systems Volume II: General-

purpose Applications System Guide (GEH-6721_Vol_II), the sections Embedded PROFINET

Gateway (Embedded PPNG) Module or PPNG PROFINET Gateway Module.

To import and configure the GSDML file

1. Right click on the PPNG and select Add PROFINET IO Device.

2. Browse and Import the GSDML file from the archive.

3. Select Add Device to add the IRIU to ToolboxST.

4. Select the imported GSDML and make sure the Device Host Name in the Configuration area is in accordance with the following figure and the following table.


The IRIU Station Name is determined using the configuration pins on the unit; the Device Host Name

must align with this selection. Configuration is made by loop-back connections between the indicated

pins in the following table, loop-back connections should be kept as short as possible to avoid the

possibility of interference.

For example, Station Name industrialriu08 is set by making a loop-back connection from J4-053 to

J4-043 & J4-019 to J4-020 and leaving J4-052, J4-041 and J4-040 unconnected.

Note: – indicates the configuration pin should be left unconnected.


5.2 Configuration and Diagnostics

There are two classes of failures of the IRIU; global failures which affect the operational integrity of the

IRIU and local failures which are isolated to a selection of interfaces.

A global failure is when an internal test failure occurs which affects the operational integrity of

the IRIU all outputs are held in a de-energized state and there are no external communications

from the IRIU. If a global failure occurs the IRIU should be retuned for repair or replacement as

defined in Repair and Replacement.

Care should be taken as the IRIU will appear in a similar state during normal operations if it has

not yet established communication with the controller. Therefore, before determining the IRIU has

a global failure the following should be confirmed;

• Physical configuration pins are as defined in

• ToolboxST Configuration and Parameters and match the Device Host Name in

ToolboxST.

• Instrumentation Power is correctly applied

• A connection exists between the IRIU and the PPNG (embedded or external)

A local failure is when an internal test failure occurs that does not affect the operational

integrity the IRIU and as is limited to a subset of functionality.

Degraded operations continue with the affected interfaces flagged as faulty by setting the

‘Interface Fault’ flag in the ‘Status bits’ of the slot Input data.

If any interface is flagged as faulty the ‘CBIT_UNIT_DEGRADED’ flag in the ‘Fault bits 00’ of the

Diagnostic slot is set. Additional diagnostic information is provided in the Diagnostic slot. If a

local failure occurs the IRIU should be retuned for repair or replacement as defined in Repair

and Replacement.


5.3 Thermocouple, Type K

The temperature is calculated from the measured thermoelectric voltage and is compensated using an internal measurement of cold-junction temperature. The measurement of the thermoelectric voltage is made through (Hw /a, /b); where (Hw /a) is the positive input and (Hw /b) the negative input. (Hw /c) provides an optional shield grounding.

The temperature is reported in degrees Celsius or Fahrenheit using (Di /a). The cold-junction temperature is reported in degrees Celsius or Fahrenheit using (Di /d). The template reports if the temperature is outside a configurable range using (Di /c). The template includes functionality to detect a sensor wire off condition which is reported using (Di /b). A software function applies additional filtering to the voltage measurement if required.

5.5 Current Input (with Loop Power)

The sensor is connected to an internal shunt resistor using (Hw /b) and uses (Hw /c) to provide loop power. An optional unit ground is provided by (Hw /d). An external loop-back is required to connect (Hw /a) to (Hw /e); loop-back connections should be kept as short as possible.

The voltage across this shunt resistor is measured via (Hw /a) and converted into an equivalent current, which is reported via (Di /a). (Di /a) is compared to two fixed ranges which is reported on; Range Check (Di /b) and Sensor Health (Di /p).

5.7 RTD, PT100 (IEC60751) 3 Wire

The RTD is excited by a resistor-isolated, DC voltage source (Hw /a) and is referenced to a (unit) ground (Hw /f). The excitation resistance consists of two resisters in series Re and Rs; where Rs is a high accuracy shunt resistor which can be used to calculate current when used with the internal voltage monitor (Hw /c). An external loop-back is required to connect (Hw /b) to (Hw /d); loop-back connections should be kept as short as possible.

The interface uses a three-wire sensing methodology. Within the three-wire methodology, inaccuracies caused by the resistance within the lead wire are compensated.

The function also provides the ability to define the range over which the temperature measurement is considered valid, and subsequently, if the temperature goes out of range, a fault status bit is reported using (Di /c). The value of the sensor is reported using (Di /a). The temperature scale is selectable between Celsius, Fahrenheit and Resistance. A software function applies additional filtering to the voltage measurement if required.

5.8 Current Output, 0-20mA

This interface drives a controlled current through an external load with resistance inside the specified Load resistance. The output current level is commanded using (Di /a) which is used to drive the output (Hw /a), the low-side of the external load must be connected to (Hw /b), where it is internally returned to ground.

The command is limited from 0 to 20mA should the input command exceed these limits. The command is set to a default value (0mA) until a valid command is applied. The voltage across resistor R1 is measured using (Hw/c) and converted into an equivalent current, which is reported using (Di /b).

The user application should compare Command (Di /a) and Current Feedback (Di /b) in order to detect problems with the interface.

5.10 Relay Drive with Fuse Monitor

This interface controls a relay and monitors the status of a fuse. The Discrete Output State is commanded using a received Command (Di /a) which is used to switch the output (Hw /a). The command is set to a default state of 'Open' before a command is received.

The intended application of the interface is to provide an output which can drive a relay coil by switching between 5VDC and Ground. The low-side of the relay coil must be connected to (Hw /b), where it is internally returned to ground.

An internal monitor (Hw /c) measures the state of the discrete output and reports this using (Di /b). The user application should compare Command (Di /a) and Relay Status (Di /b) in order to detect problems with the interface.

The interface measures the fuse voltage for the relay (Hw /d) and determines the Fuse Status which is reported using (Di /c). The Field Power voltage is monitored (external to this interface) and no change is reported in (Di /c) if the Field Power is interrupted.

5.11 Contact Inputs, Isolated

This sensor interface detects the state of a contact input.

An Excitation voltage (Hw /b) is provided through resistor (Re) which utilises the externally supplied Field Power which is nominally 24V. A pull-down resistor (Rs) within the unit enables the state of an 'Open' switch to be reliably determined.

This interface measures DC single ended voltage (Hw /a) and then applies thresholds to determine the Logic status which is reported by (Di /a).

The Field Power voltage is monitored (external to this interface) and no change is reported in if the Field Power is interrupted.

• Receiving and reporting data from the GE Sensing DPS 8000 pressure transducers.

• Providing indication of PDO freshness which should be used by the user application to determine the health of the interface.

The configuration of the DPS device needs to be set by a GE Sensing approved CANopen configuration tool prior to being installed on the CANopen bus.

The DPS sensors are not intended to be individually powered down and hot-swapping with power on is not supported.

Removing power from any single DPS sensor may have adverse effects on measurements from other sensors on the same network. When performing maintenance on any DPS sensor, always remove power from all sensors on the CANbus for at least four seconds. Perform offline maintenance using the precautions listed in the DPS User Manual and then restore power to all DPS sensors.

5.14 Dynamic Pressure, PCB Piezotronics, Dual Sensor

This is an interface to two PCB Piezotronics Differential Charge Amplifiers which are connected to differential output charge sensors.

The interface performs the following functionality for each channel:

• Hardware Conditioning: Hardware elements which condition and filter the input signal which includes bias removal.

• Wire Off Detection: Detects a sensor wire off condition (Hw /e, /f) and reports using (Di /n, /m).

• Voltage Measurement and Software Filter: Samples the signal (Hw /a, /c) and (Hw /b, /d), applies software anti-alias filtering and selectable software filtering and stores each in a buffer of depth.

• RMS: Calculates the root mean square (RMS) voltage of the time-domain sampled and filtered signal over a number of samples.

• RMS Scan Average: Calculates an average RMS using a configurable number of root mean square (RMS) voltage calculations. Calculates the pressure by scaling the average RMS using configurable parameters and outputs using (Di /a, /d).

• Windowed Fast Fourier Transform: Calculates the frequency domain peak-to-peak magnitude and bin frequency, based on time-domain sampled and filtered signal. The Fast Fourier Transform has a Bin Quantity and Range.

• Bin Exclude Control: Eliminates the frequency peak for the specified bins (Di /p(x)). Applies to both channels.

• Peak to Peak Scan Average per Bin: Provides a frequency domain peak-to-peak magnitude average per frequency bin, over a configurable number of Scans.

• Band Sort: Average frequency domain peak-to-peak data is sorted into separate frequency bands. The bands are configurable.

• Maximum Peak to Peak Average in each Band: The maximum of the average peak-to-peak magnitudes from each frequency band and its corresponding frequency bin are calculated and output using (Di /b(n)) & (Di /c(n)) and (Di /e(n)) and (Di /f(n)).


The interface performs the following functionality on the data calculated for both channels:

• Peak to Peak Average in each Band: Calculates the average peak to peak magnitude overboth channels for each band and outputs using (Di /g(n))

• Maximum Peak to Peak Average in each Band: Calculates the maximum peak to peakmagnitude over both channels for each band and outputs using (Di /j(n)) along with the channelon which it occurred (Di /h(n)) and the Frequency Bin (Di /i(n)).

• Range check each Band: The maximum peak to peak magnitude over both channels for eachband is compared to a configurable maximum threshold. The status is indicated using (Di /k(n))
