Cim 500 Modbus Tcp Communication Setup - Grundfos CIM 200 Functional Profile And User Manual

10.3 CIM 500 Modbus TCP communication setup

Step Action
1 Install CIM 500 in the Grundfos product according to the product documentation.
2 Select position 1 at the protocol rotary switch. See section
3 Power on the Grundfos product, and observe LED2 turn permanently green and LED1 remaining off.
4 Complete the product configuration, for example sensor configuration via Grundfos GO Remote.
5 Connect one of the CIM 500 Ethernet ports (RJ45) to a PC using an Ethernet cable.
Configure the PC Ethernet port to the same subnetwork as CIM 500, for example 192.168.1.1, and the subnet mask to
6
255.255.255.0. See section
7 Open your internet browser and make contact to the CIM 500 webserver. Default address: 192.168.1.100
Log in to the webserver. Default:
8 User name: admin
Password: Grundfos.
9 In the menu column to the left select: Configuration > Real time Ethernet protocol
10 Key in an IP address belonging to the same subnet as your PC, for example 192.168.1.2.
11 Key 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 while
connected to another Modbus TCP master.
