To verify the APN settings after completion, use the SMS command "APNSETTINGS".
To verify that the data connection is working, use the SMS command "APNSTATUS". The connection state must be
"Context active" if ready and "Connected" if a Modbus TCP master is already communicating.
CIU 260 is now ready to be accessed from a Modbus TCP master via a data connection, or via SMS commands.
Step Action
1 Install CIM 500 in the Grundfos booster system according to the booster system documentation.
2 Select position 1 at the protocol rotary switch. See section 7.2 Setting the Industrial Ethernet protocol.
3 Power on the booster system, and observe LED2 turning permanently green and LED1 remaining off.
4
Complete the booster system configuration, for example sensor configuration and selection of local Operating mode, local
Control mode and local Setpoint, for example via Grundfos GO Remote.
5 Connect one of the CIM 500 Ethernet ports (RJ45) to a PC using an Ethernet cable.
6
Configure the PC Ethernet port to the same subnetwork as CIM 500, for example 192.168.1.1, and the subnet mask to
255.255.255.0. See section A.1 How to configure an IP address on your PC on page 61.
7
Open your internet browser and make contact to the CIM 500 webserver.
Factory default address: 192.168.1.100
8
Log in to the webserver. Default:
User: admin
Password: Grundfos
9 In the menu column to the left, select "Configuration" > "Real time Ethernet protocol".
10 Type in an IP address belonging to the same subnet as your PC, for example 192.168.1.2.
11 Type in the subnet mask 255.255.255.0, and leave the rest of the settings at their factory default values.
12 Click [Submit] to transfer the new settings, and close the internet browser.
CIM 500 is now ready to be accessed from a Modbus TCP master via one of its Ethernet ports. Use the IP address selected under step
9. The Modbus address (Unit ID) in the Modbus TCP telegram is not used.
• CIM 500 LED1 flashes green when Modbus TCP communication takes place.
• You can use the two Ethernet ports to daisy chain CIM 500 modules.
• It is possible to have connection to the webserver simultaneously with a connection to a Modbus TCP master.
• It is possible to have connection to more Modbus TCP masters simultaneously, for example to have connection to PC Tool CIM/CIU
while connected to another Modbus TCP master.
Step Action
1 Check that both the CIU 500 unit and the booster system are powered off.
2 Remove the front cover of CIU 500.
3 Select position 1 at the CIM 500 module protocol rotary switch. See section 7.2 Setting the Industrial Ethernet protocol.
4
Connect the GENIbus cable from CIU 500 to the booster system. See fig. 5 in "CIU, Communication Interface Unit
installation and operating instructions" or see the CIU quick guide
5 Power on CIU 500 and the booster system, and observe LED2 turning permanently green and LED1 remaining off.
6 Connect one of the CIU 500 Ethernet ports (RJ45) to a PC using an Ethernet cable.
7
Configure the PC Ethernet port to the same subnetwork as CIM 500, for example 192.168.1.1 and the subnet mask to
255.255.255.0. See section A.1 How to configure an IP address on your PC on page 61
