Bit 7 is not used. If several tariffs are set in the byte then the tariff with the least significant bit is selected.
UMG 96RM-P/-CBM Deactivate energy meters / tariffs via Profibus If energy meters are assigned to a tariff then these can be deactivated via byte 3 and byte 4 (cf. activate tariffs via Profibus). Here the selection of the desired tariff is implemented in byte 3 and the clearing of the associated bits in byte 4 deactivates the energy meter.
UMG 96RM-P/-CBM Reading out measurement values via the Profibus Selected measurement values can be read out via 4 factory-set profiles and an additional 8 userdefined profiles. Here each profile has a unique profile number with which a PLC can read out the configured measurement values of a profile. Example: Reading out of measurement values from the factorypreconfigured Profibus profile number 8. The 1st byte should be set to the profile number 8 (dec.) and sent to the UMG 96RM-P.
UMG 96RM-P/-CBM Example: Using Profibus to retrieve measurement values At least one Profibus profile must be set up with GridVis and transferred to the UMG 96RM-P. PLC UMG 96RM-P Fetch measured values for this profile number. PLC process output box 1st byte = Profile number (0 ..

Digital output 1: Addr. 608 = 0 Digital output 2: Addr. 609 = 0 The current flow can up to 50mA.
UMG 96RM-P/-CBM Impulse output The digital outputs can be used for the output of pulses for the computation of power consumption. For this purpose, a pulse of defined length is applied on the output after reaching a certain, adjustable amount of power. You need to make various adjustments in the software GridVis (configuration menu) to use a digital output as a pulse one. • • • • • Digital output, Selection of source, Selection of measured value, Pulse length, Pulse value. Fig.
UMG 96RM-P/-CBM Pulse length (addr. 106) The pulse length applies for both pulse outputs and is permanently fixed via parameter address 106. 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-P/-CBM 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.
