Configuration 4.1 Necessary equipment The following equipment is needed: R100, SW version 14, Nov. 01, 2005 or later PC Tools PC Tool Link adapter. 4.2 Configuration of Dedicated Controls The configuration consists of three steps: Setting the GENIbus number in the IO 351B module, if installed. See section 4.2.1 Setting the GENIbus number in IO 351B modules, if installed. Configuration of the CU 361 control unit. Use the configuration wizard or the PC Tool WW Controls supplied on CD-ROM. See section 6. PC Tool. Configuration of the IO 111 module, if installed. Use the PC Tool Water Utility, DIP switches in section 4.2.3 or see the installation and operating instructions for the IO 111. 4.2.1 Setting the GENIbus number in IO 351B modules, if installed This module must have a GENIbus number according to the following table: Module number GENIbus number A01 (IO 351B) 41 To assign a GENIbus number to the IO 351B module, proceed as follows: 1. Switch on the power supply to the Dedicated Controls. 2. Switch on the R100 and point it at the IR window of the first IO 351B to establish connection. Note If there are more than one IO 351B module, move close to the IR window to make sure that the R100 only communicates with one module at a time. Fig. 12 IR window of the IO 351B 3. Go to the first display "Number, IO 351" in the INSTALLATION menu with the R100. See fig. 13. Set the number of the module according to the above table.

Address for bus communication The IO 111 can communicate with control systems via a bus connection. In connection with bus communication, the IO 111 is slave. As a control system must be able to identify the slave units with which it communicates, the IO 111 modules must have unique addresses. Addresses between 40 and 46 are set by means of the switches 3, 4 and 5. See table. If the DIP switches are set to bus configuration, the address of the IO 111 module is set from the control system via bus. The address can be selected between 32 and 231. As standard, the address is set to 231.

7. Fieldbus communication module 7.1 SCADA system See the installation and operating instructions for Dedicated Controls to set up communication to SCADA systems. See also section 7.2 Data communication or menu 4.3 in the CU 361. Grundfos does not supply SCADA systems. If it seems as if the SCADA system is faulty, we recommend you to contact the supplier. Note The SCADA system integrator can order a functional profile from Grundfos. 7.1.1 Communication The communication takes place via a Modbus module or a GSM/GPRS module. See section 7.2 Data communication. 7.2 Data communication The CU 361 must have a CIM module (CIM = Communication Interface Module) fitted to be able to transfer data to the SCADA system or to a mobile phone. Various CIM modules are available, depending on the type of network. The CIM module can be fitted directly in the CU 361. See section 7.3 Fitting the CIM module. For configuration of the CIM module, see the installation and operating instructions and the functional profile on the CD-ROM supplied with the module. The user must select the type of communication module fitted before a network connection can be established. The following CIM modules can be fitted in the CU 361: CIM 200 (Modbus via RS-485) CIM 250 (Modbus and SMS via GSM/GPRS) CIM 270 (GRM) (GRM = Grundfos Remote Management). Display_4.3 Fig. 17 Example, selection of CIM module and communication 28 / 60

7.2.1 Modbus network CIM 200 (Modbus via RS-485) The CIM 200 module transfers data to/from the CU 361 and the local Modbus network. See fig. 18. SCADA Modbus network CU 361 (CIM 200 built-in) TM04 3221 3908 Fig. 18 Example, CIM 200 CIM 250 (Modbus and SMS via GSM/GPRS) The CIM 250 transfers data to/from the CU 361 and a GSM/GPRS network. See fig. 19. The CIM 250 can send/receive SMS messages to/from one or more mobile phones. The CIM 250 can also send data to a remote SCADA system. Note A series of system parameters must be set before SMS messaging can be used. SCADA GSM antenna Mobile phone CU 361 (CIM 250 built-in) TM04 3697 4908 Fig. 19 Example, CIM 250 29 / 60

7.2.2 CIM 270 (GRM) The CIM 270 module is used to link with Grundfos Remote Management. GRM server GRM WebAccess GSM antenna Mobile phone CU 361 (CIM 270 built-in) TM04 3698 4908 Fig. 20 Example, CIM 270 7.2.3 Ethernet Ethernet is the most widely used standard for local networks (LAN). The standardisation of this technology has created some of the easiest and cheapest ways of creating communication between electrical units, for instance between computers or between computers and control units. The web server of the CU 361 makes it possible to connect a computer to the CU 361 via an Ethernet connection (Ethernet crossover cable). The user interface can thus be exported from the CU 361 to a computer so that the CU 361 and consequently the Dedicated Controls system can be remotely monitored and controlled. See figs 21 and 22. Note Grundfos recommends that the system administrator is contacted to arrange security protection for the CU 361 connection. In order to use the web server, the user must know the IP address of the CU 361. All network units must have a unique IP address to communicate with each other. The IP address of the CU 361 from factory is 192.168.0.102. Alternatively to the factory-set IP address, it is possible to use a dynamic assignment of IP address. This is possible by activating a DHCP (Dynamic Host Configuration Protocol) either directly in the CU 361 or via the web server. Ethernet crossover cable CU 361 TM04 3218 3908 Fig. 21 Example, Ethernet connection 30 / 60

PC with access to the CU 361 via the internet Ethernet cable for internet connection CU 361 TM04 3699 4908 Fig. 22 Example, internet connection Dynamic assignment of an IP address for the CU 361 requires a DHCP server in the network. The DHCP server assigns a number of IP addresses to the electrical units and makes sure that two units do not receive the same IP address. A standard internet browser is used for connection to the web server of the CU 361. If the user wants to use the factory-set IP address, no changes are required in the menu display. Open the internet browser, and enter the IP address of the CU 361. Now open the browser, and enter the CU 361 "Host name" (Default: CU361) instead of the IP address. The internet browser will try to connect to the CU 361. The host name can be read in the display, but can only be changed using a PC tool or via a web browser. Note DHCP requires a host name. This is the first menu display seen when the CU 361 connects. TM03 2048 3505 Fig. 23 Connecting to the CU 361 Factory setting Username: admin Password: admin When username and password have been entered, a Java Runtime Environment application starts up in the CU 361, provided that it has been installed on the computer in question. If this is not the case, but the computer is connected to the internet, then use the link on the screen to download and install the Java Runtime Environment application. 31 / 60

The connection can be established via a gateway. For more information, contact Grundfos. 33 / 60

7.3 Fitting the CIM module The CIM module must be fitted by authorised personnel. Warning Switch off the power supply to the CU 361 before fitting the CIM module. Warning Electrostatic discharge (ESD) must be avoided when fitting the CIM module, for instance by wearing an antistatic wrist strap as shown in fig. 30. Fit the CIM module as follows: 1. Remove the screw in the back cover of the CU 361. See fig. 28. Fig. 28 Removing the screw holding the back cover 2. Remove the cover. Place the cover on a plane surface, and push out the marked knockout using a screwdriver or a similar tool. See fig. 29.

11.2 Alarm settings Alarms can only be indicated if the desired alarms have been enabled. See section "Alarm settings" in the installation and operating instructions for Dedicated Controls. All fault sources are either of the analog or digital fault type. 11.2.1 Analog fault configuration Analog faults are activated if the currently measured value is outside a set limit. An analog fault can be registered as a warning or as an alarm. Alarm delay An alarm delay is typically used when a measuring signal is unstable. The signal from surface water waves may generate a high water level for a short period. An alarm delay allows time for the unstable signal to pass, e.g. for the water level to steady.
