EL6720 | Lightbus master terminal

The EL6720 Lightbus master terminal enables the connection to Lightbus devices. The terminal supports the Lightbus protocol with all its features. Within an EtherCAT Terminal network, the EL6720 enables the integration of any Lightbus slaves. The terminal has a powerful protocol implementation with many features:

Like the FC2001 Lightbus PCI card, the EL6720 can be used for connection to Lightbus networks. The terminal, however, enables a more space-saving implementation since no PCI slots are required in the Industrial PC.
