Selection of graph with maintenance technician variables . Sele ction of graph with OEM variables. The insertion of the user level in MAXA TREND program , does not represent an ex pansion of the possible functions as for SCADA prog ram , but it is relative to the single database that is opened. In fact, by opening a new database, the level returns to USER one . MAXA DAS S upervision software for maxa chillers and heat pumps 7 10 SCADA S upervisory C ontrol A nd D ata A cquisition The SCADA program is the tool used to supervise the MAXA units and it consists of the following functions: • Setting and enabling connections • Selection of the machine • Monitoring of operating variables (sensors and actuators) and status variables • Forcing machine status • Reading

10 / writing parameters • Allow ing
/ writing parameters • Allow ing to import parameters into file for updating USB pen drive (VER415) • Events log • Alarm notification (popup, email) • Library setting • Process recording 10.1 PROGE C T S The SCADA program allows you to save all the created configurations in a project file. The menu has a section devoted to the projec ts , by clicking on File option . The commands that are related to the projects are: New, Open, Save, Save As..., Recent Projects - �. The file of a project is given in “ . mosX ” format and is protected by an encryption key. A backup copy can be automaticall y created every time you make a modification or you save the file as an existing one . You can automatically load the last project by ticking the " Load last configuration " on T ools menu. 10.2 CONNE CT ION S The connection is the mean by which the computer in w hich MAXA DAS software is installed can communicate with a machine . The functions that are related to the connections are: New, Copy, Paste, Delete, Properties commands . By p ressing " Add Connection " , a main branch will be added to the tree diagram and th e p roperties dialog box will open . The connection settings depend on the " Connection Type ", in this case the "serial port" connection is selected. In our normal use , we will treat only the "standard" connections for MAXA units, i . e . Serial Port and Ethern et TCP; the other 2 modes are for very special cases. SERIAL PORT N a me = n ode name COM Port = mapped serial number on the computer Baud R ate = communication speed Parit y = c ontrol type (N one , U neven , P eer ) Stop Bits = number of stop bits (1 - 2) Data Bits = number of bit s per c h ara c ter (7 - 8) Watch Time = wait time for reconnect ion after an error condition (sec.) Delay = delay between one bus operation an

11 d the next (ms) Descri pt ion = t ex
d the next (ms) Descri pt ion = t ext field for add ing notes Read Interval Timeout = time related to receivi ng the serial buffer. This parameter can be useful in case of slow devices in transmitting the response (ms) Normally the parameters of MAXA units are Baud Rate at 9600, Even Parity, 1 Stop Bits, 8 Data Bits, Read interval Timeout at 1 ms. MAXA DAS S upervision software for maxa chillers and heat pumps 8 ETHERNET TCP N a me = N ode name Remote Host = ( IP address of connection ) Remote Port = PC remote port ( 502 port for standard Modbus) Watch Time = Time for reconnection (s) Delay = Time between 2 successive commands (ms) Descri pt ion = T ext field for add ing notes In th e main area of SCADA program there is a sheet devoted to the set up connections . You can enable or disable a connection across the c onnection properties dialog box or across the popup menu which can be displayed by a right mouse button click on the conn ection. Y ou can enable or disable a connection via this menu . It is also possible to use the " Activ e single " function, which allows to enable only the selected connection and disables the others . After establishing the connection, the blue - square turns gr een indicating that a com port has been opened correctly, otherwise a red - square will appear . To establish / terminate a connection, click on the Start/Stop menu button , or through the graphically stylized symbols with an electric plug. Connection not act ivated or failed Opening communication errors ( wrong COM , i ncorrect or unreachable IP address ) Active and correct connection MAXA DAS S upervision software for maxa chillers and heat pumps 9 10.3 CHILLER/HEAT PUMP MACHINE The machine represents the electronic object with which a communication is established. In our ca se the device could be ideally simplified t

12 o the chiller or heat pump units on
o the chiller or heat pump units on which we have to operate. The options related to the device are: New, Copy, Paste, Delete, Properties. When clicking on Add machine , a selection dialog box will be display ed with family (se r ies) tree, subfamily, model and revision. Only by selecting a revision and giving a name to the new device, you can confirm the action and continue with the setting of Properties. In some devices the branch level related to the subfamily may not be used. In this case the branch will have as description "...". Once the action of device selection is confirmed , the " Machine Properties " dialog box will automatically appear . N a me = machine name . Address = Address of the modbus slave . Ret ries = number of attempts in case of failed or incorrect response . Timeout = maximum waiting time for the response after the command is sent . Watch Time = Time period (sec.) to retry the connection of an Offline Device. It is also used to retry communicati on with wrong variables of an Online devices . Common Refresh Time = After activat ion, it allows you to refresh the v ariables simultaneously every n milliseconds (number of milliseconds of your presetting) . Max Data Byte = It d eterminates the maximum numbe r of bytes for multi ple readings of variables and parameters Fami ly, Subfamily , Model , REV : they are a non - written data located in the source library . Descri pt ion = text field for add ing notes Swap = It a llows you to invert Byte, Word and Dword functions f or special devices. Actually not use d. NB: The minimum value of MaxByteData for reading a single register at a time (word) is 2 . By entering too large values, you risk requesting readings on inaccessible registers that coul d generate errors . Normally a ma ximum size of 32 is used for a serial connection. For rem

13 ote connections this value is reduced to
ote connections this value is reduced to 2 - 4 and a higher timeout is set to be (3000 - 5000) . Device not activated or not connected Device with communication errors Active device , connected a nd without communication errors MAXA DAS S upervision software for maxa chillers and heat pumps 10 10.4 VARIABL ES The variables represent the device values that to be managed . They are automatically loaded when a new device is created depending on the belonging family (series) . From the Technician, OEM, pro ducer or administr ator level , you can change the Properties of each variable , beyond the possibility of using the following options : New, Cut, Copy, Paste, Delete. N a me = variable name Address = Modbus register Bit = Bit index i n the word, only in Boolean data type T y p e = Register type Refresh Time = Time interval between one reading and another when the “ Common Refresh Time” on “ Machine Properties ” is not enabled . IsAlarm = It indicates that the variable represents an alarm . User level = Belonging level and variable visi bility Unit of measure = It indicated the measurement unit of the variable . Descri pt ion = t ext field for adding notes Scaling: w hen this option is enabled, it allows you to manage the reading data by scaling it appropriately before being stored in the variables table (see next page ) . In the example shown in the left , the reading value is appropriately scaled so as to obtain in the table a value divided by 10 (therefore with 1 decimal) respect ing the one present in the register. The registers of MAXA d evices are of Holding Register type, and on SCADA program are identified with "4x - Output Register". The data conventionally used are the "Boolean" and "Signed Integer" types . By enabling the " IsAlarm " flag, the variable in question becomes an alarm.

14 An a larm is a higher class level of t
An a larm is a higher class level of the variable and is used to be notified by SCADA and historicized by TREND. When it is enabled, other 2 flags will appear beside the " IsAlarm ". Email = the alarm variable will be sent for notification via e - mail to the co nfigured recipient addresses ( see paragra ph 10.10 ). Popup = the alarm variable will be notified via pop - up alert box , to which successive alarms will be added . Each notification includes the occurr ing date and t ime of the alarm , Device and alarm n ame s NB : When a new device is created, the "IsAlarm" alarm flag is usually attributed . The flag is considered an indispensable information for the program in order to process the variables that identify an alarm and to memorize a lis t of the occured alarms during the recording of a process (displayed on MAXA TREND). MAXA DAS S upervision software for maxa chillers and heat pumps 11 The variable s page displays the reading value as a function of the data type . Variable is not yet read Error of variable r eading Variable was read corre c t ly In the "Mode" area, the firmware read from the unit is displayed, along with the current status, which can be changed by selecting the mode and the corresponding send button . For the units that mount the new electronics there is also the reproduction of th e leds o f the display on the machine. The values read or the following strings are present in the "Value" column : ON - OFF For values declared as booleans, such as alarms or digital inputs and outputs ERR Disconnected or broken probe NO_CNF Input not configured TIMEOUT Reading failed due to timeout (the machine did not respond the data in the configured time) If the variable is an alarm type and the value is b oolean in the ON state, the background of the corresponding cell is colored red. Furthermo re, the following command

15 keys are present : Send Mode Fo
keys are present : Send Mode Force the unit mode according to the selection Force Defrost Forces manual defrost Reset Alarms Reset all active alarms (only for units that mount the new electronics) Reset History Reset the list of all the historicized alarms (only for units that mount the new electronics and for Producer user or higher) MAXA DAS S upervision software for maxa chillers and heat pumps 12 10.5 PARAMET E R S The parameters represent the device settings to be adjust ed for each specific model. The se parameters will be automatically loaded when a new device is created according the relative series . Y ou can also change the Properties of each parameter from the Maintenance Technician , OEM, P roducer or A dministrator levels , beyond the possibility of using the following options : New, Cut, Copy, Paste, Delete actions. The setting of a given parameter is completely similar to that of a variable, except if the " Refresh Time " and " IsAlarm " properties are disabled, and the " Default Value " property is activated which identifies the value to be wri t t en . The scaling allows to manage the value from the register and it can be also used to identif y the minimum and maximum values to be introduced . Each parameter can be visible or invisible according to the user - level login . Regular visualizzation of th e parameter Communication error , error of reading and writing of all parameters The r eading and writing of the parameters can be done only through the command on the parameter’s page . The "Default Value" column is preloaded during the device creat ion and can be edited for changing the values of the parameters. But on the other hand, t he "Value" column is of readonly type and it shows the reading values. When the data in these two columns are different, the background of the corresponding "Value" cell i s colored o

16 range. The writing operations are as
range. The writing operations are as follows (a confirmation of the operation is requested before being performed): Write Parameters Writes all the parameters visible in the table Write Factory Parameters W rites all the parameters related to the configured unit, therefore also parameters not visible in the table; this function is active for Mainten er level or higher Write Single Writes the parameter of the selected row Write on Defaults Copy the values read from the unit in the "Value" colum n in side the "Default Value" column so that they are saved in the project MAXA DAS S upervision software for maxa chillers and heat pumps 13 10.6 EVENTS LOG La scheda Log rappresenta una lista di eventi relativi alla comunicazione con i vari dispositivi abilitati. The "Log" page contains a list of the communication events with all enabled devices. Th e logger is temporary as long as SCADA program remains open. But when closing the program, a persistent file event log will be updated. To configure the notification event filter, please see the paragra ph 10.10 . 10.7 PROCESS RECORDING PROCEDURE You can start to record one or more processes b y clicking on the red circle icon . The process recording will take place for all active connections, with active machines . For each recording, t he data will be sto red in a sqlite database encrypted file . NB: When starting the recording, if the connection is not open, it is forced to do so. To end the process recording, click on the red square icon. Each time you begin an acquisition, a file will be stored in the configured destination folder (see paragraph 10.10 ) . Respectively, a folder tree will be created with the name of the family (series of the machine ) , sub - family, model and revision. The file name takes the name of the mach ine with the start date and time . MAXA DAS S upervision software for maxa c

MAXA DAS S upervision software for maxa chillers and heat pumps 16 11 TREND “ TREND ” program is the tool used for ongoing or already recorded processes mangement. The program requires an active license in order to be started. The displayed and used license i s the sa me as on “ SCADA ” program . T his program is also in Italian/English languages the same as SCADA program and contains log events . 11.1 DATABASE MANAGEMENT Each file related to a recording process is in itself a “ SqLite ” format database file. The insertion of the user level, in TREND program , does not represent an extension of the possible functions as SCADA program , but it depends on the opened single database. In fact, if you open a new database, the level returns back to USER one . The effect of introducing a hig her level is related to the visualization of some variables on a graph , which are normally hidden for the lower levels. 11.2 G RA PH When

19 opening a database , the current graph
opening a database , the current graph remains white and empty. On the right side, you can select v ariables up to 12 cu rves that to be shown at the same time on the graph . You can select also the color and the t h ickness f or each curve . If a Boolean curve is selected, it will be displayed on a graph at the bottom of the screen (normally not visible if no Boolean curves sele cted). MAXA DAS S upervision software for maxa chillers and heat pumps 17 Inside the graph there is a curser which allows you to display the values of curves in a panel on the right at that special time . It is possible to scroll the cursor quickly by double - click on the desired area of the graph. The time is temporally indicated in the bottom right corner of the page where the cursor is actually positioned on the graph . It is also possible to shift from sample to sample to wards the left or the right using the appropriate arrows buttons . The bar graph at the bottom right allows you to act on the graph through some functions. The arrow buttons at the bottom left side act on the graph n avigation , they are used to shift the visualization of one or a group of samples. This button helps you to acces s to the visualization period of your selection ; the "Scale X" dialog box allows you to insert th e X scaling data. This button helps you to select the limits of visualization for the selected values; the "Scale Y" dialog box allows you t o insert th e Y scaling data. It helps you to extend the X - axis to the whole recording period. It helps you t o extend the Y - axis so as to contain all the values of the selected period. SHIFT + LEFT ( rectangle sele ction ) = Zoom on selection command . 11.3 A LARMS LOG By selecting the Alarms page , you can displ a y the list of alarms that occurred during the recording. NB: A

20 n alarm will be recorded if the variable
n alarm will be recorded if the variable on SCADA program is set to "IsAlarm". MAXA DAS S upervision software for maxa chillers and heat pumps 18 11.4 REAL - TIME By op ening a database file with SCADA software of a n actual regestration process , you will get the “REALTIME” data displayed on the graph . Basically for each additional data sample in the databese, the displayed time period will shift to left. This could happen , if the displayed time period is the last one, otherwise the "REALTIME" action will not be considered. To constrain the visualization of the graph with the last sampled pa rt , you must click the button in the bottom left bar.
