After plugging the cable adapter and powering up the computer and energy meter, it is possible to test the connection by using DOS emulated command line (on Windows command prompt).

Serial port and communication test The power meter used in this example (Actaris ACE5000 family) need following serial communication settings, according to ISO/IEC 1177:1985 : baud rate 1200 bps 7 data bits parity even 1 stop bit. The +Vcc and Vcc power are supplied by computer s RS232 DTR=ON and RTS=OFF signals, respectively. Based on RS-232 (EIA/TIA) serial port status and control output signals, some tricks can be used to supply simple data communication circuit.
Both solutions are similar, there are only few differences, as shown in figure 1. SERIAL COMMUNICATION CIRCUITS Some energy meters are equipped, either optical isolated open collector and emitter transistor, or infrared output LED. A simple solution is based on serial and IEC optical port connected to a computer running OPC. In some cases, continuous measuring and monitoring are needed, at customer s premise. Interfaces, either simple direct wired / optical isolated serial, or complex wired / wireless network types, enable suppliers to periodically read and/or control remotely, using appropriate devices and applications. INTRODUCTION There are many energy meter applications based on devices equipped with communication interfaces providing measurement information. Keywords: Energy meter reading, DLMS/COSEM, OBIS codes, exchange, OPC platform, HMI 1. Some tricks and configuration details are also presented.

These information may be transferred to another computer station and used to be displayed by hardware or software based HMI device, as can be see below. OPC server environment can integrate different devices interfaces and communication protocols and provides different parameter values as abstract information. The computer runs an application developed under OPC Server environment, used for interface, channel protocol and device configuration and data acquisition reasons. The system contains an energy meter (Actaris ACE 5000 family), one optoisolated serial adapter connected to a process computer via serial communication port. This article describe a simple meter reading example, using optoisolated serial readout circuit and a software application using OPC Client/Server environment solution. 1 238 IEC protocol based, Energy Meter Integration on OPC Access environment Florin DRĂGAN, Romul COPÎNDEAN and Rodica HOLONEC Abstract:The International Electrotechnical Commission s IEC standard suite describe direct local connections physical layer and communication protocols used for Electricity energy metering - exchange for meter reading, tariff and load control.
