EL6733 | EtherCAT Terminal, 1-channel communication interface, PROFIBUS, master/slave
EL6733 | EtherCAT Terminal, 1-channel communication interface, PROFIBUS, master/slave
The EL6733 PROFIBUS master terminal supports the PROFIBUS protocol with all features and enables the integration of any PROFIBUS devices in the EtherCAT Terminal network. The terminal features the latest PROFIBUS technology thanks to Beckhoff’s PROFIBUS chip, which was developed in-house. This includes a high-precision isochronous mode for axis control and extended diagnostic options. These masters are the only ones that support different polling rates for slaves.
- cycle times from 200 µs possible
- PROFIBUS DP
- master and slave up to 12 MBit/s
- high-performance parameter and diagnostic interfaces
- freely configurable error management for each bus device
- reading of the bus configuration and automatic assignment of the GSD files possible
Like the FC3101 PROFIBUS PCI card, the EL6733 is used to connect to PROFIBUS networks; however, it saves space since it does not require PCI slots in the industrial PC.
