1 92.460/1 EYK 230: nova230, Compact BACnet universal automation station The EYK 230 is the compact nova230 unit from the EY3600 family of systems with interface functions, equipped with a BACnet communication interface and a third-party interface. The BACnet interface supports the integration of Sauter's nova230 automation station into the open, standardised 'BACnet/IP on Ethernet basis' communication protocol as per EN and ISO This nova230 can be networked as it stands, and can communicate on novanet and Ethernet. As a BACnet server (B-BC), the necessary 'objects' with the 'properties' and the requisite 'services' for the HVAC are provided. Typical users (BACnet clients) of this information are open management systems, bus-wide operating devices, other automation stations with BACnet capability etc. In its function as a BACnet client, the communication interface supports peer-to-peer transfer with present-value properties of the specified objects. The station also comprises assemblies and interfaces that are needed for operations, connecting the devices and communicating with other stations and with the management level. Several variants with different combinations of functions are possible. Therefore, a nova230, on the one hand, can be used to control HVAC systems and, on the other, has a third-party interface (RS232 interface), via which the data of an alien system can be received or sent. An example of BACnet system topology with nova230 can be found in Appendix C of the complete PDS.

2 92.460/2 EYK 230 The card is licensed with BACstac TM and bears a licence sticker. The second licence sticker supplied can be kept in the project file or in the subsidiary company or NSO for archiving purposes and as a back-up licence. The connection from the BACnet communication interface to the automation station is an integrated connection via novanet. The supplied cable ( ) is connected to the novanet RJ11 socket. The Ethernet connection is via an RJ45 socket. Communication is effected via the transport protocol BACnet/IP. The configuration of this IP address and other parameters is done using Sauter's 'BACnet Server Configurator' software module; see BACnet AS manual The BACnet communication interface provides Sauter's DDC type nova230 with the BACnet server/client functionality. The MFAs (machine fine addresses) used in the automation station are converted into BACnet objects when the house address (data points) has been configured; the relevant BACnet object list is managed and updated automatically. This involves no additional generation work in order to integrate the BACnet functionality on the DDC level. Using the scheduler (day and week calendar), which is also provided, and the associated 'BACnet Objects Schedule and Calendar', it is possible to process local BACnet time programmes, and, therefore, to control process variables from the active AS. The DDC data points can be transferred either by BACnet clients using cyclical polling or by the COV subscription mechanism of the BACnet communication interface. Further BACnet specifications as per separate BACnet PICS (Protocol Implementation Statement). See "Sauter-BACnet-PICS.pdf". The nova230 in the various EYK 230 types comprises all assemblies and interfaces that are needed for operation, for connecting the devices, for communicating with other ASs, with the management level and with the non-sauter system. In addition, the EYK 230 F010 process the M-bus telegram traffic with the external system directly via terminals (terminals 501/502, 503/504) or via their RS232 interface. All other EYK 230 types process the telegram traffic via their RS232 interface. This occurs by means of the parameterised data-point list, which assigns the alien system's addresses to the AS software. The nova230 automation station can be fitted on a top-hat rail (EN 50022) in a motor control centre. The EYK 230 station requires a power supply of 230 V~. The earth terminals are connected with the earthing connector (PE) and the housing. The devices are connected via spring terminals. The following conditions must be met:- Cross-section of cable: min. 0,8 mm 2 (AWG 18), max. 2,5 mm 2 (AWG 13) observing the norms. novanet with twisted cable Digital inputs potential-free contacts, opto-coupler, transistors (open collectors) Digital outputs < 250 V~ / 2 (2)A to the relay contacts Analogue inputs < 10 V = Analogue outputs no external voltage Counters potential-free contacts, opto-coupler, transistors (open collectors) Description of inputs and outputs Temperature measurement Number of inputs 6 Type of inputs Ni1000 (without coding) Pt1000 (software coding) Measuring range Ni C ( F) Pt C ( F) The Ni/Pt inputs; (a) do not require calibration; (b) already take the cable resistance into account; and (c) can be used for Ni1000 and Pt1000. Linear correction factors a and b (Y = a X + b) Slope a No entry is needed here. A proportional factor, which gives the result in C, can be called up direct from the microprogram. Zero-point shift b No calibration is needed here. A line resistance of 2 Ω is included and has been compensated for. If the line resistance R is greater (deviation > 2 Ω):- b = 0,18 (R - 2 Ω) in room-temperature range or b = 0,16 (R - 2 Ω) at approx. 100 C

3 EYK /3 The sensors are connected using two-wire technology; the connecting leads can be up to 55 m (180 ft) long if 0,8 mm 2 (AWG 18) or 170 m (558 ft) if 1,5 mm 2 (AWG 15). The measuring voltage is pulsed in order to prevent the sensor from warming up. Though the inputs are intended for Ni1000 sensors, Pt1000 sensors can also be used. The type of measurement can be chosen via the software. The Ni1000 measuring value is strictly linear and better than ± 0,06 C (± 0,1 F) from 50 C to +150 C. The linearisation for Pt1000 guarantees negligible error between 50 and +100 C ( F). For the full measuring range of the Pt1000, see the following table:- Temperature Absolute difference 100 C ( 148 F) 0,05 C ( 0,09 F) C ( F) < ± 0,02 C (± 0,04 F) +150 C (302 F) +0,05 C (+0,09 F) 200 C (392 F) +0,11 C (+0,2 F) 300 C (572 F) +0,29 C (+0,52 F) 400 C (752 F) +0,10 C (+0,18 F) 500 C (932 F) 0,31 C ( 0,56 F) U/I/R measurement Number of inputs 4 Type of inputs Voltage 0 (2)...10 V, 0 (0,2)...1 V Strom 0 (4)...20 ma Potentiometer 500 Ω...2 kω Linear-correction factors a and b (Y = a X + b) The linearity can be adapted very accurately for every input. Settings for a standardised signal (0...1) Linear-correction factors Inputs a B V V ma ma 1,25 0, V 1,25 0, ma 12,5 0, V Input limit values:- Measurement of voltage < ± 50 V Measurement of current < 50 ma Loading of reference outputs < 10 ma Return line for all signals earth Accuracy U = ± 0,1% (± 0,01 V) I = ± 0,1% (± 0,02 ma) R = ± 0,5% (± 0,05 V) Resolution U = 5 mv Voltage input (U) The voltage is measured between one of the input terminals for voltage (marked with a 'U') and an earth terminal. The signal is connected at one end to the chassis and must, therefore, be either potential-free or earthed. If earthed, the chassis should have a 2,5 mm² wire (because of error). The two measurements 0 (0,2)...1 V and 0 (2)...10 V are selected by the software. The maximum voltage is < ± 50 V. The visible range, however, is limited to 10 V. The internal resistance R i of the input (load) is 60 kω in this case. Current input (I) There are special terminals (marked with an 'I') available for measuring the current. The current signal must also be potential-free. The maximum input current must be limited to 50 ma. The internal resistance R i is 100 Ω.

4 92.460/4 EYK 230 Potentiometer input (R) The potentiometer is connected to terminals U, earth and +1 V. In order not to overload the +1 V reference outputs (which are pulsed), the lowest potentiometer value should not be less than 500 Ω. The reference output is protected against short circuits. The potentiometer s upper value of 2 kω is prescribed in order to guarantee stable measurements free of interference. Pulse-meter input Number of inputs 2 Type of inputs Input frequency Max. output current of the inputs De-bounce time Protected against extraneous voltage potential-free contacts opto-coupler transistor (open collector) < 15 Hz 0,7 ma with respect to earth 20 ms up to 24 V ac/dc Potential-free contacts, opto-couplers or transistors with open collectors can be connected to the meter inputs. The maximum pulse frequency is 15 Hz. A de-bounce time of 20 ms is envisaged so that the switching contacts are correctly received. The pulse is received on the falling flank and can remain present indefinitely. The automation station's internal counter value is interrogated every cycle and stored in DW 2 as a dual partial sum. The counter values are updated approx. every sec. in DW 6 (i.e. 128 mal per hour). Through using the FP format, the counter value can have a maximum of approx. 2, With the FP format, it is possible to show counter values up to with a resolution of 1. Any counter overflow can be curbed by resetting using the 'C_Preset' function module. Digital inputs Number of inputs 16 Type of inputs potential-free contacts, with respect to earth opto-coupler transistor (open collector) Max. output current of the input 0,7 ma with respect to earth Max cable resistance 1 kω Protected against extraneous voltage up to 24 V a.c./d.c. The nova230 station processes 16 items of digital information. The monitored inputs are connected between the input terminals () and earth. Every input can be defined as an alarm or status input (standard setting is status). The station applies a voltage of approx. 12 V to the terminal. When the contacts are open, this corresponds to bit=0 (status). When the contacts are closed (equivalent to bit=1), a current of approx. 0,5 ma flows. The status change must be present for at least 30 ms; it is buffered (button function) and then processed at the next cycle. Digital outputs Number of outputs 1 0-I 3 0-I-II Type of outputs relays Outputs' loading 250 V~/ 2 A The digital outputs can also be used as 4 0-I. The feedback signals can be received (exclusively genuine) via the digital inputs. Analogue outputs Number of outputs 3 Type of outputs 2 0(2)...10 V 1 0(2)...10 V or ma Return conductor for all signals earth Error U = +0,5% (+0,05 V) I = +0,5% (+0,1 ma)

5 EYK /5 The output voltage is tapped between the relevant output terminal and an earth terminal. One output can provide 0 20 ma. The outputs are protected against static discharges and short circuits, but not against local alternating or direct current, which can destroy the protective diode and the output driver. For this reason, the device (e.g. an actuator) should always be connected in the installation first. Then a check should be made at the station to ensure that there is no potential at all (i.e. 0 V) at both wires with respect to earth and with respect to each other. If this is the case, the earth lead should be connected first, and the signal lead last, to their respective terminals in the station. Explanations The nova230 automation station has an operating program which reads in all inputs, processes the parameterised modules, updates the outputs and carries out communication with other stations or visualisation PCs. A real-time clock for the time programmes is also integrated in the automation stations. A lithium battery ensures that the user data (FBD data), time programmes and historical data (HDB) are retained in the SRAM in the event of a power failure. The real-time clock also runs off this lithium battery. The battery makes it possible to retain the data and run the real-time clock for at least 10 years without power having to be applied. Date and time are set ex works. When power is restored, the automation station checks the consistency of the data and starts communication. The user programmes can be loaded from any point in the novanet. The data stay in the batterybacked SRAM even in the event of a power failure. In addition, the data can be stored captive in a user EPROM. Therefore, the level of protection against loss of data is very high. Every station needs an AS address, which is set via coding switches. The nova230 station is available in several variants which differ in their link to the non-sauter system (see appendix). It has on the EY3600 side a green LED for power, two yellow LEDs for the novanet line (Send and Receive). It has on the side for the non-sauter link a green LED for the cycle and a red LED for fault. The nova240 control panel (EYT 240 F001, accessory) is coupled to the station via an RJ-45 socket. The control panel enables all the station's data (with the exception of the HDB) to be processed (e.g. to read measured values, alarms and status; to change setpoints; and to issue positioning commands). Putting into operation When connecting the power supply, the earthing lead must be connected to the screw provided (protection class I). When working on the unit, the power supply must be disconnected. Before being linked to the novanet, each station must be given a unique address. This AS number is binary-encoded via the block of P switches and can be between 1 and 4194 (for the BACnet stations). Off On Value Off On The AS address is set by means of the 16-digit switch-blocks. The last switch is for setting the parity, which refers to the address and not to the four other switches situated below. The parity should be set so that the number of switches in the 'on' position, including parity, is even Even Parity B10729 Example: = The following example is intended as an explanation of the binary encoding: Station number This AS number fort he EYK220F001 has to be set between 1 and 4 194

6 92.460/6 EYK 230 If the station has not already got an EPROM with the parameterised user data, they must be transmitted to the station. Communication is always effected via the novanet bus and the corresponding terminals or via the RJ- 11 connector. Programming can be done in parallel to the data traffic, though this may lengthen the response time of the other network subscribers. For this reason, the station can be separated from the novanet for the duration of the data transfer and the PC that is doing the parameterising can be connected locally. After the data have been transferred, they are immediately active. The station can then be re-connected to the network and is ready for operation. nova Off On Even Reset B C D Automation station Microprogramme (4 Mbit) Automation station User data (1 Mbit) Protocol, microprogramme (512 KBit) B07770 You are strongly advised to store the AS user data in the AS user data EPROM as well; this can be loaded with any normal programming device. Switch off the power supply before opening the station. Protective measures to prevent electrostatic discharges must be taken before performing any work on the unit. Reset: ON Reset B C D The reset switch should be set to 'ON' for approx. ½ s, causing the station to load the user data from the EPROM and to start operation under defined starting conditions. B04726 Finally, the reset switch on the automation station has to be reset. If the reset switch is left in the ON position, the station remains in the reset mode and cannot function correctly.

7 EYK /7 The nova230 has in the top left-hand corner three LEDs which indicate the status of the automation station:- The green Power LED, when lit continuously, indicates that the power supply is on. The yellow Receive LED, when flashing, indicates telegram traffic on the novanet. In standalone mode (without novanet), this LED remains unlit. The yellow 'Send' LED, when it flashes, indicates that the telegram is being sent from the AS. It shows, therefore, the telegram cycle or the internal cycle of the AS. In stand-alone mode, the LED flashes faster, because the AS is sending only dummy telegrams.

10 92.460/10 EYK 230 Appendix A nova230 M-bus (EYK 230 F010) engineering On the AS with M-bus interface, 60 machine fine addresses are used for AS functionality, leaving up to 192 transfers (software addresses) for M-bus communication. It should be noted that, when software addresses are used for the automation function, the number of transfer addresses falls accordingly (max. 192 transfer addresses X soft addresses for AS functions). Using a suitable parameterising program, the project technician must make a data-point list of the non- Sauter system s source addresses and the target addresses of the EY3600 system. These transfer data (data-point list) are then transferred into the serial EEPROM using a download function via the RS232 interface. The requisite parameterising program can be downloaded from the Sauter intranet. The nova230 has a direct M-bus (meter bus) connection and an RS232C interface. Therefore, the non-sauter bus can be connected either direct via the M-bus connection terminals (terminals 501/502, 503/504) or via the RS232C interface using an interface converter (also called a repeater). If the direct M-bus connection is used, the M-bus cable can be up to 1 km in length if the cable used has a capacitance of max. 50 nf per km. In this case, up to 40 loads can be connected directly, which load the bus with 1,5 ma (standard). If more loads are required, a repeater which communicates via the nova230 RS232C interface should be used. When parameterising the automation part using CASE-FBD, select nova230 (ILext) under AutomationStation.

11 EYK /11 Appendix B Compact AS: EYK 230 (from variant F040) engineering On the AS with alien-bus interface, 60 machine fine addresses are used for the AS functionality, so a maximum of 192 transfers (software addresses) remain for alien-bus communication. It should be noted that, if software addresses are used for the automation function, these are at the expense of transfer addresses (max. 192 transfer addresses X soft addresses for AS functions). Parameterising is done by the project technician using a parameterising program. The project technician creates a list of the alien system's data points with their properties (function code, source address etc.). Depending on the protocol, it is necessary to decide on which memory address (AS number, MFA and data word) and with which card code the translated value in the nova system is to be transferred. These transfer data (data-point list) are then transferred into the serial EEPROM by means of a download function via the RS232 interface. A parameterising program can be downloaded from the Sauter intranet.

In total, this AS has 256 MFAs (machine fine addresses) of which up to 192 software MFAs are available for the transfer with the alien system (e.g. M-bus, Modbus, LON). The parameterising of the AS and the provision of the signal to the alien system is done using the 'CASE FBD Editor' software in accordance with IEC The transfer list is parameterised using a parameterising program with download function.
