Address for bus communicationThe 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.

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.

7.1.1 CommunicationThe communication takes place via a Modbus module or a GSM/GPRS module. See section 7.2 Data communication.

7.2 Data communicationThe 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).

7.2.2 CIM 270 (GRM)The CIM 270 module is used to link with Grundfos Remote Management.


7.2.3 EthernetEthernet 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.

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.

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.

This is the first menu display seen when the CU 361 connects.
