1 GENERAL This manual contains information about the CEM 05100 Ethernet communication adapter, which is an adapter of the serial communication adapter (SCA) family for electronic electricity meters manufactured by ABB AB. Throughout this manual the CEM 05100 Ethernet communication adapter will be referred to as the SCA or the adapter. The purpose of this manual is to give the user a good overview and understanding of the features the CEM 05100 Ethernet communication adapter offers.
2.2 TYPE DESIGNATION Below are tables with explanation for all positions in the type designation for the SCA.

3.1 STATUS LED The status LED, part 6 in figure 1, indicates the state of the SCA. The chart below describes the state of the SCA and how the status LED indicates this. Status LED Green Flashing Green Off Red SCA Status Link has been established and OK. Transferring data. No link established or power off Fatal Error. Table 2: Table over the status LED indication. 4 TROUBLE SHOOTING Status LED Off Cause No link. Off No power to SCA. Red Fatal error.
5 TECHNICAL DATA Network Protocol and Standards Compatibility Data protocols: TCP/IP, UDP, DHCP. Power Supply Nominal voltage: Voltage range: Frequency: Power consumption: Terminal wire area: Recommended tightening torque: 100-240 V AC -20 % to +15 % of nominal voltage. 50/60 Hz ± 5 % 0.80 VA at 230 V AC, 50 Hz. 0 – 2.5 mm² 0.
5.1 DIMENSIONS The physical dimensions of the SCA are displayed below. Power 1 4 ABB IR Interface Ethernet D51 Figure 3: The physical dimensions of the SCA. 6 AUTOMATIC METER READING The ABB Ethernet communication adapter provides Automatic Meter Reading (AMR) using M-Bus protocol over UDP or TCP over a network. This is done transparently without altering the original MBus telegrams.
Maximum Demand. Voltage Event Log. Current harmonics. Please refer to the User’s Manual of the electricity meter for more information of what quantities can be readout depending on the type of electricity meter. 7.1 ACCESSING THE WEB SERVER This section will describe how to access the built-in web server in ABB Ethernet communication adapter. To access the SCA for the first time, the IP-range of the local area network used must be 192.168.1.x, with 192.168.1.10 free for the SCA to use.
7.2 ODINSINGLE ENERGY RESET The Read meter-page of the SCA also has a button to reset the resettable energy-register in the ODINsingle electricity meter. This button only has an effect on electricity meters with resettable energy registers. Other meters will ignore the command. If one or more users are added to the SCA, only an administrator can issue an energy-reset. If no users exist, then anyone can issue the command. 7.
login requires neither. The guest without login type means that only an administrator can change settings, but anyone can access the meter-data readout. 7.3.1 SECURITY From a security-perspective, the SCA is designed to be used in a private network. It is not intended to be used in a public network like the Internet. 7.3.2 USER ADDING AND LOGGING IN Enter the Add user menu and add a user by filling in the fields below and submit.
Restart the web browser and a login window will appear. Login with username and pass. 7.3.3 GUEST WITHOUT LOGIN USER-TYPE A guest without login-type user can be added to the system, no username and password is required to be entered when creating this type of user. To login as this type of guest, click OK without entering any login information when prompted. If a user tries to login a few times, or if Cancel is pressed, then the following page appears, explaining how to login without a password.
7.4 CONFIGURING ADAPTER SETTINGS This section will describe how to configure the ABB Ethernet communication adapter’s IP-address both statically and by a DHCP-server. 7.4.1 ASSIGNING IP-ADDRESS STATICALLY Enter the Module Setup by clicking on the Module Setup tab. Uncheck the Enable DHCP check box and enter the information for static IP-address.
Click Save and restart to send the new settings to the SCA. The SCA reboots automatically and implements the new setup. Wait a few seconds before attempting to access the ethernet module again. 7.4.2 ASSIGNING IP-ADDRESS THROUGH DHCP-SERVER. Click on the Module Setup link and check the DHCP checkbox. The IP settings will then be received from a DHCP server when the SCA is restarted. Click the Save and restart button to save changes and restart the module.
7.4.3 TIMEOUT CONFIGURATION The AMR timeout in the Module setup page of the SCA is a way to ensure that a connected electricity meter communicates in only one way at any given time: UDP, TCP or via the web server. The timeout is locked to one protocol, and is released either when the protocol closes the connection or when the timeout limit is reached. If the AMR timeout is set to 120 seconds, then the maximum time which the SCA waits for more communication is 120 seconds.
8 ABBREVIATIONS AND ACRONYMS 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over twisted pair wiring. DHCP Dynamic Host Configuration Protocol, An Ethernet protocol specifying how a centralized DHCP server can assign network configuration information to multiple DHCP clients. The assigned information includes IP addresses, DNS addresses, and gateway (router) addresses. IP Internet Protocol, The main internetworking protocol used in the Internet.
