UMG 96RM-M M-Bus interface Cable connections The M-Bus interface is designed with the UMG 96RM-M as a 2-pole plug contact and communicates via the MBus protocol. Twisted screened cable should be used for connections via the M-Bus interface. The UMG 96RM-M loads the M-Bus with an M-Bus device load of 1.5 mA. • Cable paths should be designed to be as short as possible. • Maintain as much distance as possible to power cables and to consumers (e.g. electrical motors, neon tubes, transformers).
UMG 96RM-M Cable type Bus structure The cable used must be suitable for an ambient temperature of at least 80 °C. • All devices are connected in a star, line or tree structure, whereby each device has its own address within the bus (see also Parameter programming). • A subdivision of the network structure into individual segments is implemented via repeaters (line amplifiers). • Up to 250 subscribers can be connected together in a single segment.
UMG 96RM-M Tree structure • This topology combines the star and line structures. Repeaters generally divide the branches into individual segments. Thus in the event of a fault only a specific branch is affected and so a fault in the bus system can be quickly localised.

UMG 96RM-M Device address (addr. 000) If several devices are connected to one another via the M-Bus interface, a master device can only differentiate between these devices by means of their device addresses. Therefore, each device in a network must have a different device address. Addresses can be set in the range from 1 to 250. C The adjustable range of the device address is between 0 and 255. The values 0 and 251 to 255 are reserved and may not be used. Secondary device address (addr.
UMG 96RM-M Baud rate (addr. 001) Mean value A common baud rate is adjustable for the M-Bus interfaces. The baud rate must be chosen to be a uniform value in the network. The parameter data bits (8), parity (even) and stop bits (1) are permanently set. Mean values are formed over an adjustable for the current, voltage and power measured The mean values are identified with a bar the measured value. The averaging time can be selected from a list fixed averaging times.
UMG 96RM-M Averaging method Minimum and maximum values After the set averaging time, the exponential averaging method used achieves at least 95% of the measured value. All measured values are measured and calculated every 10/12 periods. Minimum and maximum values are determined for most of the measured values. The minimum value is the smallest measured value that has been determined since the last reset. The maximum value is the largest measured value that has been determined since the last clearance.
UMG 96RM-M Mains frequency (addr. 034) For automatic ascertainment of the mains frequency, an L1-N voltage larger than 10Veff must be applied to the voltage measurement input V1. The mains frequency is then used to calculate the sampling rate for the current and voltage inputs. Adjustment range: 0, 45 .. 65 0= automatic frequency determination. The mains frequency is determined from the measurement voltage. 45..65 = fixed frequency The mains frequency is preselected.
UMG 96RM-M Energy meter Reading the active energy The UMG 96RM-M has energy meters for active energy, reactive energy and apparent energy.
UMG 96RM-M Harmonics Total Harmonic Distortion (THD) Harmonics are the integer multiple of a mains frequency. The voltage mains frequency for the UMG 96RM-M must be in the range between 45 and 65 Hz. The calculated voltage and current harmonics refer to this mains frequency. Harmonics up to 40x the mains frequency are recorded. THD is the ratio of the root mean square value of harmonics to the root mean square value of the mains frequency.
UMG 96RM-M Measured value relay Changeover time (addr. 039) All measured values are calculated every 10/12 periods and can be recalled once per second on the measured value displays. Two methods are available for retrieving the measured value displays: Adjustment range: 0 .. 60 seconds If 0 seconds are set, no changeover takes place between the measured value displays selected for the measured value relay. The changeover time applies for all display change profiles.
UMG 96RM-M Measured value displays User password (addr. 050) After return of the power supply, the UMG 96RM-M shows the first measured value panel from the current display profile. In order to keep the selection of measured values to be displayed arranged in a clear manner, only one part of the available measured values is preprogrammed for recall in the measured value display by default.
UMG 96RM-M Clear energy meter (addr. 507) Rotation field direction The active, apparent and reactive energy meters can only be cleared together. The rotation field direction of the voltages and the frequency of phase L1 are shown on the display. The rotation field direction indicates the phase sequence in three-phase systems.

UMG 96RM-M Commissioning Applying the measured current Applying the supply voltage The UMG 96RM-M is designed for connecting ../1 A and ../5 A current transformers. Only AC currents and not DC currents can be measured via the current measurement inputs. Short circuit all current transformer outputs except for one. Compare the currents displayed on the UMG 96RM-M with the applied current.
UMG 96RM-M Rotation field direction Checking the measurement Check the direction of the voltage rotation field on the measured value display of the UMG 96RM-M. Usually there is a "clockwise" spinning rotation field. If all voltage and current measurement inputs are correctly connected, the individual and sum power ratings are accurately calculated and displayed.
UMG 96RM-M Check the sum power ratings If all voltages, currents and power ratings for the respective phase conductor are correctly displayed, the sum power ratings measured by the UMG 96RM-M must also be correct. For confirmation, the sum power ratings measured by the UMG 96RM-M should be compared with the energy of the active and reactive power meters at the power feed.
UMG 96RM-M M-Bus interface Number of data points The data of the parameter list and measurement values list can be accessed via the M-Bus interface with the help of the primary or secondary address. Changing these values is not possible via the M-Bus. The number of data points to be transmitted for the RSP_UD2 telegram is defined via this address. The primary device address is factory preset to „1“.
UMG 96RM-M Measurement signal level Structure of the RSP_UD2 telegram The data transfer in the M-Bus network is implemented through modulation of the supply voltage, whereby the voltage for a high signal is 36 V and 24 V for a low signal. The slave device answers the master via the modulation of its current draw, whereby the high signal is 1.5 mA and the low signal is 11-20 mA.

Adjustment range: 1 .. 1000 1 = 10ms Default: 5 = 50ms Due to the minimum pulse length and minimum pulse pause, the values in the table are for the maximum number of pulses per hour. Pulse length Pulse pause Maximum pulses/hour The typical pulse length for S0 pulses is 30 ms.
UMG 96RM-M Pulse value (addr. 102, 104) The pulse value specifies how much energy (Wh or varh) should correspond to a pulse. The pulse value is determined by the maximum connected load and the maximum number of pulses per hour. If the pulse value is specified with a positive sign, pulses will only be issued if the measured value also has a positive sign. If the pulse value is specified with a negative sign, pulses will only be issued if the measured value also has a negative sign.
