3 General Description ENERGY MASTER is a device for panel- or DIN-Rail-mounting, which thanks to its integrated RS485 port and non-volatile memory- can autonomously read and store measurements from a network of up to 128 Elcontrol Energy Net Energy Analysers. Via a Ethernet or RS232+MODEM connection it is possible to establish communications between the ENERGY MASTER and a remote PC and perform the following tasks: Configure the Energy Master. Automatically detect the connected Energy Analysers. Download the files containing the measurement and energy counters data using with the following modes: manual, programmed or automatic. Set up and receive alarm messages when measured values exceed user-defined alarmthresholds. Remotely manage relay-outputs of the Energy Analysers (if available). Energy Master can be set to execute measurement surveys on weekly or flexible basis (Start/Stop Date/Time) Composition of ENERGY MASTER Basic Kit: 1 Energy Master 1 Set of DIN-Rail Adapter 1 Set of screws/nuts fixing Energy Master 1 RS485 Network connection cable 1 External Power Supply 1 Ethernet Cross-Cable 1 EMClient Software CD 3

CYCLE n+1 Wait. = Cycle Time - Cycle Duration At the end of each day a binary file will be available for each device connected to the RS485 network. This file will contain all values corresponding to the selected registers. This binary file can be converted to a text-file (for reading via spreadsheet) to obtain monthly or flexible historical files. Every 5 minutes: COUNTER CYCLE 1 Cycle Number = 1 MEASURE CYCLE 1 Wait end of 5 COUNTER CYCLE 2 MEASURE CYCLE 2 Wait end of 5 Cycle Number > 1 COUNTER CYCLE 1 MEASURE CYCLE 1 MEASURE CYCLE 2 MEASURE CYCLE n Wait end of 5 COUNTER CYCLE 2 At the end of each day a binary file will be available for each device connected to the RS485 network. This file will contain all values corresponding to the selected registers and the counters values at 5 minutes intervals. This binary file can be converted to a text-file (for reading via spreadsheet) to obtain monthly or flexible historical files 5) Select the polling Type : Recursive: Polling is always active Campaign: Polling is active only within the time-intervals defined in the Campaign section. Selecting the Campaign polling type, enables the related section of the setup, which allows setting two types of campaign: - Timed: Campaigns are activated/stopped following a sequence of set start and stop dates/times. - Weekly: Campaigns are activated/stopped basing on preset intervals for each day of the week. Further to the above, the Campaign section allows choosing if Alarms should be always active or only during the set campaign intervals. 9

10 6) Select the ID Num. of each device with the mouse and then click on the Alarm: Priority or Alarm: Regular buttons to call up the related windows and choose the parameters to be checked by the alarm function. REGULAR ALARM (max one alarm for each device) The parameter associated to the regular alarm is checked once every measurement cycle. The user can set the number of consecutive readings for which the parameter s value must exceed the set thresholds, before the alarm message is notified. CYCLE 1 Regular Alarm CYCLE 2 Regular Alarm CYCLE n Regular Alarm CYCLE n+1 PRIORITY ALARM (One for the whole network of devices) The parameter associated to the priority alarm is checked every 2 or 4 seconds, independently from the normal polling cycle. As for the regular alarm the user can set the number of consecutive readings for which the parameter s value must exceed the set thresholds, before the alarm message is notified. 10

11 Priority Alarm checked every 2 seconds: Read register Priority Alarm Read register Priority Alarm Read register Priority Alarm Read register Priority Alarm checked every 4 seconds: Read register Read register Read register Priority Alarm Read register Read register Read register Priority Alarm 7) To update Energy Master with the set configuration, click on the Send Configuration button. 8) The Remote Connection sub-menu allows enabling incoming messages from Energy Master to PC in case of memory getting exhausted, alarm signalling, etc. As for the communication from PC to Energy Master, the user can set Ethernet or Modem communication. In case of Modem communication, it is necessary to set the telephone number, username and password needed to access the remote PC. If the chosen mode of Ethernet connection is via IP address (see New Connection section), the sub-menu Remote LAN Settings is available. The default setting is Dynamic IP and the server to which Energy Master is connected assigns automatically a free address. If, on the contrary, a Static IP address is chosen, it is necessary to set the IP address and Subnet Mask. Default: Indirizzo IP Subnet Mask

12 9) Modify Date / Time synchronises the clock settings between Energy Master and the PC. Alarm Logs Clicking on the LOG Alarms button displays the below menu where the user can choose to display and/or save to file the historical log of regular and priority alarms, as well as a list of currently active alarms. This function can be limited to the currently connected Energy Master unit or extended to all units monitored via the same PC. 12

13 Device Relay Management It s possibile to read ( READ ) and change ( SEND ) the status of the relays of any device connected to the Energy Master via the EMClient software. The relay management function can be used only if the polling is not active. Note: The reading of the relays status must be considered indicative. The actual closing/opening of the relays cannot be guaranteed. Note: STAR3DIN and DMM3 have a single alarm relay. Note: STAR3, VIP396, SIRIO have two alarm relays. Note: The local settings on each device must be such as to allow the remote management of the relay(s). Please refer to the User Manual of the device. Data Transfer Data Transfer from Energy Master to PC can be initiated manually by clicking on the Download Files button in the main program window or automatically (see section New Connection ). If the data is downloaded manually, it s possible to chose between the following sets of data: Historical Data transfers all data-files present on the Energy Master and related to days preceding current date. 13

14 Current Data Files allows choosing specific devices connected to the network (selecting their ID Num. ) and downloading their data, related to the current day. The file will be automatically downloaded and converted. Note: When the free memory on the Energy Master becomes lower than 40Mb, the automatic data download procedure of all data is activated. In order to be successful, the Enable Calls option must be enabled in the Remote Connection sub-menu of the Energy Master Setup. File Conversion Data is stored as binary files on the Energy Master and thus it is necessary to convert them to text-files in order to read them using any usual spreadsheet application (such as MS Excel). The conversion can be done in two ways: 14

15 Monthly File Conversion All files (containing all measures from all connected devices) related to one month are converted into one text-file for each device. In order to limit the quantity of information contained in such files, the user can choose if all records available in the binary files should be converted (selecting All in the Record section) or to adjust the frequency of the records in the output-file by choosing to convert only 1 record every xx. Selected Files Conversion This mode of conversion is useful if it is necessary to focus on the data related only to specific devices and within specific time-frames. As for the previous mode, the number of records can be adjusted to the user s needs. 15

This file contains all information related to the requested measurement registers. If Energy Master has been set for 5 Minute-Interval readings, a separate file will be saved, containing all information related to the energy counters. The name of the mentioned files is 11 characters long and identifies the devices and the date of the file: AAAYYYYMMDD.cin A = Device Address Y = Year M = Month D = Day The files can be downloaded starting from the date following the day to which the polling was related to and, once transferred to the PC, will be saved in the folder of the respective month (for example /4/bin for the files of April). The conversion of the binary files generates TAB-separated text-files that can be imported into MS Excel or similar spreadsheet applications. The mentioned text-file will consist of a short part containing the data necessary to identify the device and the data itself. Each column corresponds to one of the measured parameters and every record is marked with the corresponding date and time. Current Data Files If necessary the temporary files related to the current date can be downloaded and automatically converted. In this case, the corresponding files will be saved in /DIRECT and their structure/format will be identical to that of the previously described historical files. Alarm Log-File The list of alarm events found on each single or all Energy Master units can be saved into a Log-File. Example - Log-file priority alarm: 25
