High-End Meter Demonstration Board

1 Introduction

The STEVAL-IPE006V1 is an integrated system designed to provide a complete demonstration of a high-end solution for power metering. It shows no compromise measurement of active, reactive and apparent energies, load management and automatic meter reading via a power line modem, antitampering both on neutral wire and meter box, surge protection and in-application programming. The demonstration board is supplied directly from the mains through a high performance switch mode power supply. The measured values can be observed on the board's LCD or through the serial interface on a PC screen. All the parameter settings are changeable using this GUI. For safety reasons, the power supply and metering parts are galvanically isolated from the rest of the board.

Application engineers can use this board to evaluate the components or to get started quickly with their own power meter product development project. All software and firmware source codes, gerber files and the bill of material are provided to help you get started easily and allow you to focus on the specific requirements of your application.

The Power Meter Demonstration Board is a 2-layer PCB, its overall dimensions are 130 x 130mm. The location of the control buttons and connectors is shown in Figure 3.

Figure 3. Control buttons and connectors

In order to prevent electric shock and to provide direct safe connection of the meter to the PC using the serial cable, half of the board is galvanically decoupled by transformers (T2 and T3) and opto-couplers (U1, U3 and U4). You can see the position of the division line on the bottom side of the board.

The system can be divided to several sections:

● Energy meter section

● Power supply section

● Power line modem section

● Microcontroller section

● Peripherals section

Each section is described below. For a more detailed and complete description of the used components refer to the product datasheets and application notes listed in Appendix A on page 44.

Hardware Description High-End Meter Demonstration Board

5.1 Energy meter sectionThe STPM01 is an ASSP designed for effective measurement of active, reactive and apparent energies in a power line system using Rogowski coil, current transformer and/or shunt sensors. This device can be implemented as a single chip1-phase energy meter or as a peripheral measurement in a microcontroller-based 1-phase or 3-phase energy meter.The meter section measures the current both in the phase and the neutral wire to enable the tamper detection feature. To obtain the tamper state, you can read the tamper status bit (BIT) displayed in the firmware menu on the LCD or in the main software window.The current sensor consists of the current transformer T1 and resistors R20, R21 (or T2 and R22, R23 for the secondary current channel). This combination of values gives a sensor sensitivity constant 1.8mV/A.The voltage sensor is created from a voltage divider (resistors R26, R27, R28 and R24). Its sensor sensitivity is 0.709mV/V.The components C16, C17, R16, R17, C18, C19, R18, R19, C20, C21 and the voltage divider resistors are anti-aliasing filters of the relevant STPM01 analog inputs.The high-end meter application uses the STPM01 in peripheral mode although you can also use stand-alone mode for testing. You can access the LED and stepper motor pulses (MOP and NOM) outputs on the relevant pins. You can change the configuration using the PC software suppled with the board or the STPM01 Manager with an additional programmer (see UM0128) which can be plugged into the SPI connector (reference J46).

Warning: This external programmer does not contain any kind of galvanic isolation. To avoid the risk of the electric shock or the damage of your computer connect the demonstration board to the mains through an isolation transformer.

5.2 Power supply sectionThe L6590 is a monolithic switching regulator with internal power switch, reference and protections designed in BCD OFF-LINE technology, able to operate with a wide input voltage range and to deliver up to 15W output power. The device is equipped with a standby function which automatically reduces the oscillator frequency from 65 to 22kHz under light load conditions to enhance the efficiency.

Note: As an alternative to the L6590 see also the VIPerX2A SMPS solution (AN1715).

The L78M05 and LF33 are fixed voltage linear regulators. Each type employs internal current limiting and thermal shutdown.The power selector jumper (J14) enables you to choose the board 5V power supply source, i.e. the ST7538 internal regulator or the external L78M05 circuit.

5.3 Power line modem sectionThe ST7538 is a half duplex synchronous/asynchronous FSK modem designed for power line communication network applications. It operates from a single supply voltage and has an integrated line driver and 5V linear regulator. Additional functions such as watchdog, clock output, output voltage and current control, preamble detection, time-out, band-in-use are included.

The power line coupling filter was designed for 82.05kHz frequency to simplify the user power line communication tests in the CENELEC A band used by energy suppliers.

5.4 Microcontroller sectionThe µPSD3334 is a powerful 8051-based microcontroller with a flexible memory structure, programmable logic, rich peripheral mix, watchdog, and a low-voltage reset, forming an ideal embedded controller. The 8032 core is combined with the Programmable System Device (PSD) architecture to optimize the 8032 memory structure, offering two independent banks of Flash memory (256 and 32K) that can be placed at virtually any address within 8032 program or data address space, and easily paged beyond 64 Kbytes using on-chip programmable decode logic.

5.5 Peripheral sectionThe M41ST87 Serial TIMEKEEPER®/Controller SRAM is a low power 1280-bit, static CMOS SRAM organized as 160 bytes by 8 bits. A built-in 32.768kHz oscillator (controlled by an internal crystal) and 8 bytes of the SRAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format. An additional 11 bytes of RAM provide calibration, status/ control of alarm, watchdog, tamper and square wave functions. 8 bytes of ROM and finally 128 bytes of user RAM are also provided. Addresses and data are transferred serially via a two-line, bi-directional I2C interface. The M41ST87 has a built-in power sense circuit which detects power failures and automatically switches to the battery supply when a power failure occurs. Two fully independent tamper detection inputs allow monitoring of multiple locations within the system.The supercap is used instead of a battery for the RTC device backup due to its longer lifetime and the fact that the meter is supplied from the mains most of the time when it is in operation. The installed value 0.22F/5.5V is enough for retaining the memory content for at least 1 week of power outage.The M24512 is an I2C compatible electrically erasable programmable memory (EEPROM) organized as 64k x 8 bits with more than 100,000 Erase/Write cycles.The measured energy and power values plus time and date information (16 bytes in total) are stored in this memory every 5 seconds for the automatic meter reading function. This arrangement records the data curves for a period of over 5.5 hours. In a real metering application the storing period is much longer as well as the total recording time.The end of the memory space is reserved for the STPM01 configuration and calibration data. These values are loaded in the STPM01 shadow RAM memory after the board reset and then used for the demonstration board operation. OTP memory is not used, it is free for user test purposes.The ST3232 is a 3V powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements and high data-rate capabilities.The MC1602 is a standard 16 characters x 2 lines display.

Note: The board assembly does not include the IrDA transceiver due to a wrong pinout on the PCB.

High-End Meter Demonstration Board Software Description

23/47

6 Software Description

The PC software included with the Power Meter Board displays all the measured data, enables access to the internal registers and configuration bits of the embedded components (STPM01, RTC, ST7538) and demonstrates the power line communication, the automatic meter reading functions and the loading curve transfer.

The source code files are supplied on the included CD. The firmware was developed using Keil uVision2 V2.37 (C language) and the software was developed with Microsoft Development Environment 2003 Version 7.1.3088 (Visual C++).

To set up the communication, run the software, choose the COM port that the meter board is connected to, and click on the Connect button. If the COM port is properly installed and no other application is using it, the Connect button stays pressed.

6.1 Main software windowThe main PC software window (Figure 8) displays the active, reactive, apparent and active base band energy data, voltage and current rms values, mains frequency and meter status bits. If you click the Update button, these values will be updated approximately every second. To directly access the board connected to the COM port, do not select Concentrator mode. This mode is only for power line communication.

6.2 Component registers

6.2.1 STPM01

This dialog box shows all the configuration and mode bits of the STPM01. You can modify them and write them to the circuit by clicking the OK button. The meter will change its operation immediately in accordance with the new settings. For example, you use this dialog box to easily observe the effect of the calibration bits.

Figure 9. STPM01 configuration bits

Note: A good tip is to leave the RD bit set so that the STPM01 works with the corresponding OTP shadow latches and in this mode test the other configuration bits.

To get complete definition of each bit refer to the STPM01 Datasheet.


25/47

6.2.2 M41ST87

The M41ST87 dialog box displays the content of the RTC registers and configuration bits. You can edit the field with new values. when you click the OK button they are written to the circuit. This dialog box allows you to easily test the states of the tamper push-button sensors.

Figure 10. M41ST87 registers


26/47

Figure 11. M41ST87 configuration bits

Note: To start running the RTC, deselect the oscillator stop bit (ST), power down time-stamp halt bit (HT) and tamper event time-stamp enable bits (TEB1, TEB2).

For complete description of the M41ST87 memory refer to the product datasheet.


27/47

6.2.3 ST7538

The ST7538 Control Register dialog box (Figure 12) displays the physical parameters of the power line communication and the other features of the ST7538 and allows you to change them. You can adjust the link layer parameters using the power line communication (PLC) settings dialog box (Figure 14).

Figure 12. ST7538 control register

For a more detailed and complete description of the ST7538 device refer to the product datasheet.

6.3 Power line communicationFigure 13 shows power line communication (PLC) connection scheme. Up to 65535 demonstration boards can be connected to the network. The boards are identified by their own unique Meter address numbers. To test the communication, set a different address for each board in the network (see Figure 27), connect your PC to any of the boards using the serial cable, specify the destination address of the board you want to communicate with in the PLC dialog box (Figure 14) and select Concentrator mode in the main window (Figure 8). Then any requested operation will be performed with the remote board.

6.3.1 Frame structure

This chapter briefly presents the frame structures and error correction scheme used in this meter PLC demonstration. The implementation conforms to the CENELEC rules.

Figure 15 shows the structure of a power line frame. It contains the following fields:

● Preamble. This field is used for training and synchronizing the receiver modem. It simply consists of a sequence of ‘0’s and ‘1’s.

● Header. This field marks the start of the useful frame data. Its value is very different from the preamble (0x9B58).

● Domain address (DOA) (1).

● Control field (CTRL) (1).

● Network protocol control information (NPCI) (1).

● Source address (SA). The address of the frame transmitter.

● Destination address (DA). The address of the frame receiver.

● Application data. This field contains the transported data.

● Frame check sequence (FCS). This field contains cyclic redundancy check (CRC) value generated using the polynomial x16 + x15 + x2 + 1 from all the fields in the frame (excluding preamble, header and FCS itself). It enables a corrupted frame to be identified and discarded.

Note: 1 These fields are transferred but are not checked either by the transmitter or by the receiver.

Figure 15. Frame structure

Figure 16 shows the structure of an acknowledgement frame. It contains the following fields:

● Preamble. The same field as in the data frame.

● Header. This field has the same purpose as in the data frame but its value is 0xE958.

● Frame check sequence (FCS). This field repeats the FCS field of the transmitted data frame.

Figure 16. Acknowledgement frame structure

All bytes starting from the domain address field including the FCS field are transmitted with a forward error correction (FEC) scheme that adds a further 6 bits to every byte (see Figure 17). These additional fields are calculated through the use of the generator polynomial x6 + x5 + x4 + x3 + 1 and are complemented so that a byte containing 0 is encoded with a non-null value. This redundant information enables correction of up to three consecutive erroneous bits.

Preamble Header DOA CTRL NPCI SA DA Application data FCS

2 bytes 2 bytes 2 bytes 1 byte 1 byte 2 bytes 2 bytes 64 bytes 2 bytes

Preamble FCS

2 bytes 2 bytes

Header

Figure 17. Forward error correction scheme

6.4 Automatic meter readingThere is a circular buffer defined in the meter EEPROM. The measured values (i.e. active energy, reactive energy, active power and reactive power) are stored in this buffer every 5 seconds. To read this data, press the "AMR" button. You can interrupt the reading by pressing the "Stop" button at any moment. After reading, the data are automatically displayed on your monitor (see Figure 18).

Figure 18. AMR graph

1. The read data are displayed from the zero address of the circular buffer. This means that the oldest records are not always displayed on the left side of the graph. To avoid this problem and make the new records start from address zero, click on the Reset button in the main software window.

2. The data are stored only if the RTC is running. Therefore you should remove all tamper conditions (reset bits HT, TEB1, TEB2) and set the correct time and date.

8 Additional features

8.1 In-System ProgrammingThe In-System Programming (ISP) feature allows you to change the whole content of the µPSD3334 (i.e. memory, configuration and programmable logic) without controlling the 8032 through the JTAG interface. The FlashLINK JTAG programming cable is available from STMicroelectronics and PSDsoft Express is available at no charge from www.st.com/psm.

8.2 In-Application ProgrammingThe µPSD3334 memory structure that includes two independent Flash memory arrays capable of read-while-write operation making it ideal for In-Application Programming (IAP). The meter firmware provides support through the RS232 port. To begin programming, connect the demonstration board to your PC using the serial cable, power-up the board and enter bootloader mode (see Figure 29) by resetting the board while pressing the KEY ONE button. Run the Uploader software (see Figure 30), choose the corresponding serial port number and press the Connect button. Then you can perform the following operations:

● Erase - erases bank0 of the main Flash memory

● Program - programs the new firmware in bank0 of the main Flash memory (you'll be asked to enter the firmware hex file name after pressing this button)

● Reset - resets the main Flash memory state machine embedded algorithm (it must be executed after any error condition that occurs during Erase or Program operations).

The bar at the bottom of the software window shows the progress.

The bootloader itself is not accessible. If a failure occurs during programming you should repeat the process again.

Figure 30. Uploader

8.3 Self TestThis feature was originally developed for testing the boards in production. But you can use it for verifying the board functionality at any time. You can use it to check the KEY buttons, SENSOR buttons, LCD, ICs (PLM, EEPROM, RTC, STPM01) and roughly calibrate the meter.

To accomplish these tests, execute the following steps:

1. Connect the power source and the load to the board (see Figure 31)

2. Connect the board to your PC using the RS232 cable

3. Power up the board

4. Run the test software, select the appropriate COM port number, specify the name of the test report file and click on the Start button to start testing (see Figure 32)

5. Perform the actions required by the test software.

You will get a successful/fail result at the end of the tests. You can see the test details in the report file.

Note: The higher load current you use for the calibration, the more precise results you get. But do not exceed the maximum ratings (listed in Table 2).
