A high performance, applications specific Embedded Real-Time Operating System (ERTOS) ensures high rate of data transfer with minimum latency. The ePAQ-9100 Multifunction Gateway can also serve as a Substation Data Concentrator and provide significant expansion capability via numerous IEDs and traditional hardwired I/O (RTU).
The ePAQ-9100 was designed to provide the transition form today’s RTU’s to tomorrow’s fully automated substations. Therefore, as your substation communication and automation needs expand, the ePAQ-9100 can grow right along with you. The ePAQ-9100 can be utilized in different configurations, ranging from simple to complex. A sampling of these applications is described below.
IED/SCADA Integration Platform Building on the previous example, the ePAQ-9100 can handle the addition of serially connected Intelligent Electronic Devices such as relays, meters, and controllers for reclosers and regulators. In addition, these devices could use different protocols like DNP3, Modbus RTU or Cooper 2179.
Legacy RTU to Substation LAN Gateway IED’s are beginning to be available with Ethernet connections via 10/100BaseT or 100 Base FX. The ePAQ-9100 can be configured with an Ethernet interface that supports both 10/100 Base TX or 100 Base FX. The Ethernet Interface supports both UCA 2.0 (OSI and TCP/IP) and DNP3 over TCP/IP.
Substation LAN to Legacy SCADA/EMS Master Building on application #3, the ePAQ-9100 can collect data from the networked substation devices and disseminate it to the legacy master in its required format. This configuration allows you to upgrade your substations with the latest IED’s without having to upgrade your legacy Master Station.
SCADA Web Server While the ePAQ-9100 is collecting data from field devices, as well as servicing Master Station data requests, it can support a web page. The web page can be used as a local or remote HMI to view real time substation data, while all of the other functions are being processed.
Automation Platform Using QEI’s Programmable Logic and Communication Controller (PLCC) software module, the ePAQ-9100 can be transformed into an automation processor, capable of locally controlling various processes right at the substation. PLCC uses an Excel spreadsheet Integrated Development Environment for the user to write programs to perform logical, mathematical and closed loop control operations.
I/O interface and the power section. Main Processor and Memory The ePAQ-9100’s Main Processor section is made up of a Motorola 68331 32-bit microprocessor, a clock generator and watchdog timers. The microprocessor handles all I/O and communications services.
It is called the Maintenance Port because its main function is to provide a clean, simple interface to the test technician, allowing him to control and query the status of the ePAQ-9100 or its data. This port is also used for downloading software, configuration tables, etc. This is an RS-232 interface port supporting only software handshaking.
LEDs for communications status on the ePAQ-9100’s front panel. 3.2.8 IRIG-B Interface The ePAQ-9100 supports the IRIG-B format in one of two distinct forms. A transformer coupled analog input channel (amplitude modulated time sync packets), or a serial input channel (a digital representation of the signal at RS- 422 levels).
6AIP1 for a maximum total of 128 possible analog input points. The API also includes two fixed reference points at +/- 4.5 Vdc. The ePAQ-9100 has a 0 to +/- 5Vdc, 12bit A/D converter that converts collected analog values to digital values. These values are then stored in RAM. A DC/DC converter in the ePAQ provides power and isolation for the 6AIP1’s.
The SPI, under program control, reads the state (0 or 1 value) of the digital points in the selected 6SIP1 panel. This value is stored in RAM for further processing. Via a 26pin IDC header (STATUS), 6SIP1’s can be connected to the ePAQ-9100 via ribbon cable.

Point data is never "Queued-up, to be read later" between any of the clients and servers. Time-stamps are generated at the data source, and QEI's status sampling technology allows millisecond (or better) accuracy of actual transition-time recording without any skew introduced through the debouncing process.
Security: One relay operation at a time. Connector: 34-pin IDC header. NOTE In ePAQ-9100 unit equipped with the Local I/O option, the control voltage required to operate control relays IS generated within the ePAQ-9100. 5.1.13 Physical Dimensions 17.125 in. L x 17.000 in. W. x 3.437 in. H.
