TCP and UDP protocols. Like all other ABB serial communication adapters, the ABB Ethernet communication adapter have the size of 2 DIN-modules and follows the ABB’s pro M- standard, which defines mechanical dimensions, way of mounting (35 mm DIN-rail) and design outlook.
220 - 240 V Optional functionality No options Functional upgrade Table 1: Type designation of ABB Serial Communication Adapters. 3 INSTALLATION 1. Disconnect the power supply. 2. Strip the wires and connect them to the top terminals of 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 SCA Status Green Link has been established and OK. Flashing Green Transferring data.
5 TECHNICAL DATA Network Protocol and Standards Compatibility Data protocols: TCP/IP, UDP, DHCP. Power Supply Nominal voltage: 100-240 V AC Voltage range: -20 % to +15 % of nominal voltage. Frequency: 50/60 Hz ± 5 % Power consumption: 0.80 VA at 230 V AC, 50 Hz. Terminal wire area: 0 –...
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 M- Bus telegrams.
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.
7.3 USER AND SECURITY MANAGEMENT This section will deal with the user management feature in the ABB Ethernet communication adapter. It will discuss how to add and remove users and setting their privileges and settings.
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.
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.
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.
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.
