Page 26: Usb
Service USB communication serves as a fast peer‐to‐terminal data link. The device is detected by host as a USB 2.0 compatible device. Service USB connection is provided through a USB mini‐B type connector. Service USB is intended only for parameterisation of the meter and is not galvanic separated. Advantage is that in this case meter does not need a power supply to communicate. Communication via service port is time limited. When using service communication, power supply and measuring voltages need to be disconnected. WARNING! Service USB communication is not galvanic separated! When using service USB communication, power supply and measuring voltages need to be disconnected! PLEASE NOTE When MC3x0x is connected to a PC through USB communication for the first time, a user is prompted to install a driver. The driver is integrated in MiQen software or can be downloaded from the Iskra, d.d. web page www.iskra.eu.

It is constant and its influence on the accuracy is increased by decreasing measuring signals. It is present also when measuring signals are not connected and it occurs at all further calculations as very sporadic measurements. By setting a common starting current, a limit of input signal is defined where measurements and all other calculations are still performed. Starting current for all powers (mA) Noise is limited with a starting current also at measurements and calculations of powers. Starting voltage for all powers Noise is limited with a starting voltage also at measurements and calculations of powers. Until voltage reaches user defined starting voltage limit, all powers are set to 0. Using three wire electrical connections, virtual phase voltage is used in calculations. Starting voltage for SYNC (MC350, MC350H and MC330 only) If all voltages are less than Starting voltage for SYNC, than the current inputs are used for synchronisation.

Day program sets up to 4 time spots (rules) for each day group in a season for tariff switching. A date of real time clock defines an active period. An individual period is active from the period starting date to the first next date of the beginning of other periods. The order of seasons and starting dates is not important, except when two dates are equal. In that case the season with a higher successive number has priority, while the season with a lower number will never be active. If no starting date of a season is active, the active period is 1.

Page 49: Explanation Of Basic Concepts
A device measures all primary quantities with sample frequency which cannot exceed a certain number of samples in a time period. Based on these limitations (65 Hz∙128 samples) a sample factor is calculated. A sample factor (M ), depending on frequency of a measured signal, defines a number of periods for a measurement calculation and thus a number of harmonics considered in calculations. Average interval − MP Due to readability of measurements from LCD and via communication, an Average interval (M ) is calculated with regard to the measured signal frequency. The Average interval (see chapter Average interval on page 41) defines refresh rate of displayed measurements based on a sampling factor. Power and energy flow Figures below show a flow of active power, reactive power and energy for 4u connection. PLEASE NOTE Display of energy flow direction can be adjusted to connection and operation requirements by changing the Energy flow direction settings in general / connection (see page 28).

Communication. Structure of the input/output telegram When Iskra MC350H Profibus enters the Data Exchange operation mode then standard SRD (Send and Request Data with acknowledge) telegrams are exchanged between Master device and MC350H device. Iskra defines one output telegrams (master to slave) and 4 input telegrams (slave to master), to provide data information being exchanged. Output telegram is used to write data into the output module registers. And the input telegrams are used to read one of four modules with measuring data. Telegrams are defined on the data section field (data field up to 244 Bytes long) inside the SDR message structure. The purpose of telegrams definition is to provide exchange of measurements data from MC350H to the Master device and to control MC350H outputs from the Master device. MC350H output telegram is defined as: Master telegram to the Slave Meaning/contents Value Header byte 0 Telegram ID – or module number of the data 1‐5 segment to be requested Header byte 1 reserved‐not used at this time Header byte 2 control byte WRXXX XXXDU Header byte 3 reserved‐not used at this time Data bytes 4‐128 up to 124 bytes of user data user data being exchanged Measuring centres – MC320, MC330, MC350 & MC350H ‐ User’s Manual ... - Page 72 Header byte 3 status byte XXXUP XXIDX Data bytes 4‐128 up to 124 bytes of user data user data being exchanged Header byte 0 indicates the module number index being requested. With this number (1‐5) MC350H indicates to the Master which module of data is being transferred inside the SRD data section. Header bytes 1 and 2 are not used. Header byte 3 is used as a status byte with the following meaning. B7 B6 B5 B4 B3 B2 B1 B0 X X X UP X X ID X With bit 4 (UP) set to 1 MC350H indicates to the Master that internal data update is in progress. Value 0 means that internal data processing completed. With bit 1 (ID) set to 1 MC350 signalizes to the Master that telegram ID inside the header byte 1 is wrong (not in the range 1‐5). This prevents errors when addressing wrong input telegrams at the Master output telegram. 64 Measuring centres – MC320, MC330, MC350 & MC350H ‐ User’s Manual ...
