Description

The PROFIBUS master terminal EL6731 supports the PROFIBUS protocol with all its features. Within an EtherCAT Terminal network, it enables the integration of any PROFIBUS devices. Thanks to the PROFIBUS chip developed in-house, the terminal is equipped with the latest version of the PROFIBUS technology – including high-precision isochronous mode for axis control and expanded diagnostic options. These masters are the only ones that support different poll rates for the slaves. Features:
