The purpose of this FDS is to highlight and describe in detail the functionality and operation of the AIM System. Section 1: AIM® System 1.0 Overview & Fundamentals The AIM® System is designed to monitor and evaluate the condition of steam and process equipment.

WirelessHART communication protocol. WirelessHART uses IEEE 802.15.4 compatible radios operating in the 2.4GHz Industrial, Scientific, and Medical radio band. The radios employ direct-sequence spread spectrum technology and channel hopping for communication security and reliability, as well as TDMA synchronized, latency-controlled communications between devices on the network. This technology has been proven in field trials and real plant installations across a broad range of process control industries. Each device in the mesh network can serve as a router for messages from other devices. In other words, a device doesn’t have to communicate directly to a gateway, but just forward its message to the next closest device. This extends the range of the network and provides redundant communication routes to increase reliability. The AIM® wireless gateway determines the redundant routes based on latency, efficiency and reliability. To ensure the redundant routes remain open and unobstructed, messages continuously alternate between the redundant paths. Consequently, like the Internet, if a message is unable to reach its destination by one path, it is automatically re-routed to follow a familiar, redundant path with no loss of data. The mesh design also makes adding or moving devices easy. As long as a device is within range of others in the network, it can communicate. WirelessHART Obstruction Table 10: Wireless Mesh 9 AIM® Functional Design Specification 3.1 WirelessHART Securities The WirelessHART technology is designed to enable secure industrial wireless sensor network communications while ensuring ease-of-use is not compromised. Security is built in and cannot be disabled. It is implemented with end-to-end sessions utilizing AES-128 bit encryption. These sessions ensure that messages are enciphered such that only the final destination can decipher and utilize the payload created by a source device. 3.2 WirelessHART Data Protection Security features associated with privacy aim to prevent eavesdropping by unauthorized devices inside or outside the network. A common network encryption key is shared among all devices on a network to facilitate broadcast activity as needed. Encryption keys can be rotated as dictated by plant security policy to provide an even higher level of protection. A separate 128 bit join encryption key is used to keep data sent and received during the joining process private. The join key also serves as authentication to the security manager that the device belongs to this network. The join key is treated separately from the other keys to enhance security. Join keys can either be unique to each device, or be common to a given WirelessHART network based on the user security policies. Data Protection security features associated with Integrity ensures that data sent over the wireless sensor network has not been tampered with or falsified. WirelessHART computes an encrypted message integrity check field that is added to each packet. The receiving device uses this message integrity check field along with the protected data to confirm the contents of the packet have not been altered. The message integrity check field also protects the network routing information as well. This prevents attacks that attempt to change the packet’s network/transport layer information. Data Integrity also involves verifying that the packet has come from the correct source. The network/ transport layer message integrity check field, the information used to generate the check field, and the sender/receiver unique session key that codes/decodes the data are tools that can be used to verify the source. 3.3 WirelessHART Network Protection A wireless sensor network also needs tools to protect it against attacks. Network security depends upon techniques to support Authentication, Authorization, and Attack Detection. An AIM® gateway and the AIM® devices joining the network must be configured to control which devices are allowed to access the network. The network will only be secure if all the devices in the wireless network maintain security. An AIM® gateway therefore has a secure authentication process which it uses to negotiate with all joining devices to ensure they are legitimate. As with all other network communications, all join negotiation traffic is encrypted end-to-end. 10 AIM® Functional Design Specification 3.4 WirelessHART Co-Existence with other wireless systems Co-existence is defined as “The ability of one system to perform a task in a given shared environment where other systems have an ability to perform their task and may or may not be using the same set of rules.” Successful co-existence is measured by the reliability of each network to deliver its messages to the desired destination. Therefore, each network must be able to accomplish its objective while not disrupting the ability of another network to complete its objective. Problems can occur when two or more packets of information are transmitted at the same time and frequency such that they “collide” in the same physical space. If networks aren’t designed to minimize or avoid these occurrences, unreliable communications will result. There are several techniques that can be used to minimize network interference: • Channel hopping – changing the frequency channel • Time Division Multiplexing – varying the time of communications • Power Modulation – low power transmission • Direct Sequence Spread Spectrum • Mesh networking supports large physical space with low power instruments • Blacklisting and channel assessment In the data link layer of the WirelessHART protocol, packet acknowledgment with automatic retry assures data is not lost if interference does happen to occur. 3.4.1 Channel Hopping As specified by IEEE802.15.4, the 2.4 GHZ ISM frequency band is divided into 16 non-overlapping frequency channels. WirelessHART instruments use a pseudo-random channel hopping sequence to reduce the chance of interference with other networks, such as IEEE802.11b/g (Wi-Fi) which operates in the same ISM frequency band. Pseudo-random channel hopping inherent to WirelessHART instruments ensures that they do not fix on using a channel being used by an IEEE802.11b/g network for any lengthy period of time. Together with the other techniques listed, the probability of interference is minimal either way. 3.4.2 Time Division Multiplexing A WirelessHART network utilizes Time Division Multiple Access (TDMA) technology to ensure that only one instrument is talking on a channel at any given time. This prevents message collisions within the WirelessHART network. A network is provided with an overall schedule which is divided into 10 msec timeslots. At any time, only one pair of instruments are communicating on the same frequency channel, however, it is possible that more than one pair of instruments can communicate at the same time using different channels. In most cases, only one pair of instruments is communicating in a given timeslot so the WirelessHART network will not monopolize the frequency spectrum that is shared with other wireless networks. 11 AIM® Functional Design Specification 3.4.3 Power Modulation The IEEE802.15.4 radios were chosen because they are relatively low power instruments suited to wireless process control applications, as well as being readily available at a reasonable cost. The radios are used with 10dB amplifiers to allow communication of up to 200m to the next instrument, which in turn can serve as a router to pass the message along. In cases where the full distance is not required, WirelessHART instruments can transmit at a lower power to reduce the chance of interfering with other networks in the ISM frequency band. The lower transmit power of WirelessHART instruments also means that any chance of interfering with a IEEE802.11b/g Wi-Fi network is small. 3.4.4 Direct Sequence Spread Spectrum Direct Sequence Spread Spectrum (DSSS) technology provides about 8dB of additional gain utilizing unique coding algorithms. The transmission is spread over the entire frequency of the selected 802.15.4 channel. Devices with the correct decoding information can receive the data while others see the transmissions as white noise and disregard it. This allows multiple overlapping radio signals to be received and understood only by other devices in their own networks. 3.4.5 Mesh Networking The use of mesh networking technology complements the use of the low power IEEE802.15.4 radios. With mesh networking, instruments do not need to have a direct transmission path to the network Gateway. It is only required that any instrument be able to communicate to any other instrument in the mesh network. Each AIM® ST5700 device is capable of routing the message of other devices along a route that will ensure the message is received at its ultimate Gateway destination. Mesh networks also provide path redundancy and thus achieve better reliability than if each device were required to have a direct line of sight path to the Gateway. The mesh network can adapt to changing communication and other environmental conditions to find a reliable communication path to the Gateway. 3.4.6 Blacklisting and Channel Assessment In conjunction with channel hopping the WirelessHART network can be configured to avoid specific channels that are highly utilized by other networks and therefore likely to provide interference. However because most networks are not loaded continuously this is rarely required. To further avoid any conflict with other neighboring networks an AIM® Device listens to the frequency channel prior to transmitting data. If other transmissions are detected the AIM® Device will back off and attempt the communication in another timeslot on a different frequency. 12 AIM® Functional Design Specification Section 4: AIM® Wireless Gateway 4.0 Overview & Fundamentals The AIM® wireless gateway connects AIM® WirelessHART self-organizing networks with host systems and data applications. Modbus communications over RS-485 or Ethernet provide universal integration and system interoperability. The OPC functionality from the gateway offers a means to connect to newer systems and applications while providing a richer set of data. The AIM® wireless gateway provides industry leading security, scalability, and data reliability. Layered security ensures that the network stays protected. Additional devices can be added at any time. There is no need to configure communication paths because the gateway manages the network automatically. This feature also ensures that the AIM® devices have the most reliable path to send data. 4.1AIM® Wireless Gateway Functions • • • • • Builds and maintains the MESH network.

The gateways are capable of coordinating a network of up to 100 points. If there are more than 100 points within a monitored area, additional gateways will be needed and their networks will overlap. 5.1 Required Information When installing the AIM system it is important to consider the location of the monitored points and the gateway and the possible communication paths while minding distances and obstructions. Typical communication distances are listed in Armstrong’s AIM manual # IOM-256-A , page 2 of 16. 5.2 Best Practices See “Designing a WirelessHART Network” in Armstrong’s AIM manual # IOM-256-A, page 2 of 16. 5.3 Network Installation The communication network will automatically form in the field when the transmitters are installed. It is important to remember that each network behaves individually. Therefore each network that is setup must have direct communication with the gateway associated with that particular network. 16 AIM® Functional Design Specification Section 6: HART Field Communicator 6.0 Overview & Fundamentals The HART Field Communicator supports WirelessHART devices, letting the user to configure, maintain, or troubleshoot devices.

The AIM® software displays this information in easy to read symbols indicating trap and battery status. 7.1AIM® Monitor Software Functionality/Description Functionality: The AIM® software monitors and manages data from the AIM® wireless system. The gateways allow for only 100 points to be viewed, while AIM® software allows for a limitless number of points. By combining all of the gateways into one central location the user can manage all of the data for the entire system. AIM® software reduces the amount of time spent on monitoring systems by simplifying the output fields. The AIM® ST5700 output fields displayed in the gateways are: 1 = good trap, 2 = cold trap, and 3 = blow through trap. The Software translates the values it receives from the gateways and relays them as a trap status. Each trap status is expressed as an icon and a description. Data connectivity issues, No Data Available, Device not configured and Out of Service are displayed in the trap status field so corrective action can be taken to restore communication. Furthermore, the software notifies the battery status, Battery Good, Battery Low and Battery Critical. Table 13: AIM® Software status legend The software summarizes total quantities of trap status and displays to the right of each condition. AIM® software can group traps together creating reporting groups. The reporting groups allow the user to organize monitoring points into areas for more finite analysis. 20 AIM® Functional Design Specification 7.2AIM® Monitor Software User Interface: The AIM® software interface will display the information from the AIM® devices in the field in an easy to read pass/fail user interface. Large, easily identified icons are used allowing the user to quickly scan the trap population and identify steam trap failures. • • • • • • • • • • • • The steam trap monitoring points are displayed as such: Trap Tag # = Trap equipment number Trap Status = Symbol of the current trap status Temperature = Current Pipe Temperature at steam trap Trap Type = The generic type of steam trap Critical = Identification if trap is critical State Change Timestamp = Time at which the trap changed from the state it was previously, to the state it is currently Monitor Tag = Tag of the monitoring device Burst Rate = Identifies the transmission time intervals Monitor Status = Displays the current status of the monitoring device Battery Status = Symbol of the current battery condition Gateway = Identifies the gateway the monitoring device reports to • • • • • • • • • • • Table 14: AIM® Software User Interface The AIM® software has a filter feature for equipment status allowing the user to quickly identify failed equipment or equipment in an alarm status. 21 AIM® Functional Design Specification 7.3 AIM® Software System Requirements Supported Microsoft Windows® Operating Systems Windows 7 x86 (32-bit) Windows 7 x64 Vista x86 (32-bit) Vista x64 XP x86 (32-bit) XP x64 Yes Yes Yes Yes Yes Yes Computer and Software Requirements: RAM Software CPU Other Network Minimum: 512 MB RAM Recommended: 1GB RAM Microsoft .NET Framework version 3.5 SP2 Microsoft SQL Server Compact 3.5 SP2 Microsoft Internet Explorer version 6.x or higher recommended Adobe Acrobat version 7.0.7 or higher Intel® or AMD® processors Disk Space 2 GB free space DVD drive LAN TCP/IP network connection to the HartIP network. 22 AIM® Functional Design Specification Section 8: SteamStar® 8.0 Overview & Fundamentals SteamStar® is an analytics software that manages single or multiple facilities steam assets and provides real time energy and emissions losses. The basic reporting package includes an executive summary, defective reports, recommendation reports, and complete log detail report. SteamStar® also has advanced reporting tools that provide benchmarking, trending, emissions, work order and multi-site reports. SteamStar® is used as an on-going maintenance tool to help manage steam assets and minimize energy losses by utilizing the AIM® wireless monitoring system to update the steam trap condition real-time. Once the steam trap is updated in the database from AIM®, SteamStar® calculates the energy losses based on the steam trap model, size, type, steam pressure, steam application and time in service. SteamStar® can be setup as a cloud hosted solution or as a client hosted solution. If client hosted, SteamStar® can be used as a global reporting tool for steam asset management and maintenance. 23 AIM® Functional Design Specification 8.1 Software Homepage The homepage is dashboard view of how all sub sites are performing. 24 AIM® Functional Design Specification 8.2 Steam Asset Database All steam assets can be tagged and tracked for real-time condition reporting.
