Page 4: Introduction
1 INTRODUCTION 1.1 KCI 4 S0 KCI 4 S0 from Zennio is an S0 to KNX interface that makes it possible to integrate S0- pulse generators into the KNX installation. Specifically, up to four S0-pulse generators can be connected independently to the inputs of KCI 4 S0, which will interpret these S0 pulses as energy, water or gas consumption measurements, depending on the external S0-compliant meter that has been connected. -

Page 7: Consumption Data Resets After A Download
To make use of calendar-dependent functions, such as periodical registers or the register initial dates, an external clock (such as the one in Z41 from Zennio) should be present in the installation in order to synchronise the KCI internal clock. -
Page 8: Configuration
Zennio KCI 4 S0 2 CONFIGURATION 2.1 GENERAL KCI 4 S0 incorporates four input channels for connecting up to four S0-pulse generators. Which ones will be in use is the first thing to configure. On the other hand, two one-bit alarm objects will be available in the project by default, besides of Date and Time of Day objects (see section 1.4). - Page 9 Zennio KCI 4 S0 Figure 2: General. Four checkboxes (one per input channel) let the integrator select which input channels will be in use. Additional entries will be included in the tab menu on the left depending on the number of active inputs.
- Page 10 Zennio KCI 4 S0 “Date”: its value will become periodically updated according to the internal date of the device. It can also receive values from an external clock for synchronisation purposes. “Time of Day”: its value will become periodically updated according to the internal time of the device.

Zennio KCI 4 S0 2.2 INPUT S0x 2.2.1 CONFIGURATION Each input channel of KCI 4 S0 can be particularised for two different scenarios, depending on the type of the S0-pulse generator connected to it: Electrical energy consumption meters. Water or gas volume consumption meters. - Page 12 Zennio KCI 4 S0 The cost of the consumed energy, according to a certain tariff. Consumption notifications are available for each register, together with power and flow alarms (provided that the calculation of the power and flow has been enabled) as well as pulse monitoring alarms.

Page 13: Total Register
Zennio KCI 4 S0 Pulses per Unit Energy (or volume): sets the pulse frequency, in pulses per kilowatt-hour (pulse/kWh) or pulses per cubic metre (pulse/m3). The available range is 1 to 65535 (the default is “1000”). CO2 Ratio: sets the hundredths of a kilogramme of CO2 released to the atmosphere per unit consumption (0.01 kgCO2/kWh or 0.01 kgCO2/m... - Page 14 Zennio KCI 4 S0 the value of the corresponding cost and CO2 emissions. Therefore, it reflects the per- input values accumulated since the device start-up. The initial value of the register can be set in parameters, being either a fixed value (such as ‘0’) or the last value that may have already been saved in the register prior to...

Page 17: Partial Registers
Zennio KCI 4 S0 2.2.3 PARTIAL REGISTERS Up to three partial registers are also available per input, which will monitor consumption during different periods of time. As the total register, they can record consumption data itself, as well as other variables such as CO2 and cost. -
Page 18: Electric Power (Or Water/Gas Flow)
Zennio KCI 4 S0 Energy Units, Initial Consumption, Additional Objects and Sending Mode, as well as the objects involved, are all of them similar to the analogous parameters in the total register (section 2.2.2). Periodic Reset: activates or deactivates the automatic reset of the partial register whenever a certain period expires: ... - Page 19 Zennio KCI 4 S0 When the instantaneous value method has been selected, the electric power (or water/gas flow) will be calculated whenever a pulse arrives. The result of such calculation, therefore, can never be zero as there must be some consumption.
- Page 20 Zennio KCI 4 S0 ETS PARAMETERISATION Once the electric power or water/gas flow functions have been activated in the input (see section 2.2.1), the “[S0x] Power (4 bytes)” and “[S0x] Power (2 bytes)” objects (or the analogous for water/gas flow) will be shown in ETS, as well as a specific screen containing the following parameters.
- Page 21 Zennio KCI 4 S0 Note: the assumption of null power (or flow) is always performed according to the minimum power (or flow) value configured above. However, these two values may condition when it is actually reported to the bus. Example: null power may not be sent depending on the parameterisation.

Page 22: Tariff
Zennio KCI 4 S0 2.2.5 TARIFF For every register, it is possible to calculate the monetary cost of the accumulated consumption, together with the consumption corresponding to each tariff (for up to two registers per input), in case of a time-slot based tariff system. -
Page 23: Notifications
Zennio KCI 4 S0 Bear in mind that only after enabling the Tariff function the Cost and Consumption in each tariff parameters will be available under Aditional objects, within the parameter screens of the registers. Enabling such function also brings the following objects to the project topology: “[S0x] Set Tariff”, which allows setting the current tariff (from 1 to 4). - Page 24 Zennio KCI 4 S0 Figure 12: Input S0x – Notifications Notification ‘y’: activates or deactivates notification number ‘y’ and therefore the “[S0x] Notification ‘y’” binary object. Register: sets the register containing the variable to be monitored. Only currently enabled registers will be displayed.

Page 25: Alarms
Zennio KCI 4 S0 2.2.7 ALARMS In addition to notifications and battery alarms, KCI implements two electric power (or water/gas flow) alarms and one pulse monitoring alarm. Power and flow alarms Every input channel incorporates an alarm function to monitor the power (or flow) - Page 26 Zennio KCI 4 S0 ETS PARAMETERISATION The Alarms tab will be available after enabling such function in the Configuration screen (see section 2.2.1). The available parameters are: Figure 13: Input S0x – Alarms Electric Power (or Water / Flow) Alarms These parameters will only show after enabling the power (or flow) calculation function in the Configuration screen.
- Page 27 Zennio KCI 4 S0 Action: sets the value to be sent (“1” or “0”) through the “[S0x] Excess Power” or “[S0x] Excess Flow” objects on the activation of the alarm. Periodic sending: activates or deactivates the periodic resending of the alarm object.
- Page 28 Zennio KCI 4 S0 Pulse Monitoring Alarm Monitoring Period: maximum time (in the range 1 to 65535 seconds, minutes or hours) the absence of pulses will not be considered an alarm situation. The value “0” disables this function. Action: sets the value to be sent to the bus (“Send 1” or “Send 0”) through the “[S0x] Alarm: Pulse Receiving –...

Page 29: Initialisation And Power Loss
Zennio KCI 4 S0 2.3 INITIALISATION AND POWER LOSS After an ETS download (as long as bus power is present): The initial energy or volume accumulated value of each register will be the one set in parameters (zero by default), unless the option to keep the previous value has been parameterised (see section 2.2). - Page 30 Zennio KCI 4 S0 The energy and volume objects will either recover their previous values or be updated according to the increments measured during the absence of bus power – in such case, they will be sent to the bus if the option to send them on a value change is active and if the increment has been greater than the minimum change parameterised.

Page 32: Annex I: Power Calculation
Zennio KCI 4 S0 ANNEX I: POWER CALCULATION KCI 4 S0 can dynamically obtain the value of the electric power or the water / gas flow rate by monitoring the pulse reception. Consumption Figure 14: Pulse Reception. The scenario shown in Figure 5 represents an example. KCI 4 S0 will be receiving discrete pulses at certain instants, as the energy, water or gas consumption increases. - Page 33 Zennio KCI 4 S0 Note that the lower the power calculation intervals (and the higher the pulse frequency), the higher the accuracy of these results. In other words, to obtain the instant power value (and not an approximation) it would be necessary to take infinitesimal intervals and to have a continuous (non-discrete) reception of consumption increments.
- Page 34 Zennio KCI 4 S0 actually sent to the bus, a power threshold can be parameterised so that, after the time period corresponding to that power elapses with no pulse reception, the power is assumed to be zero. Example: Power Calculation Methods.
