Serial Network Link - Ethernet/RS232/RS485 Gateway
SNL2-E allows the connection of two serial end devices. The serial interfaces can be configured via software as RS232 or RS422/RS485 interfaces. A mixed operation mode is possible. Additionally, terminating resistors can be switched on via software for operating the RS485 bus. Operation in TTY mode can be via an external adapter. Both interfaces support full duplex DMA mode operation. In synchronous operation mode, rates of up to 1 Mbit/s can be reached. An increase to 2 Mbit/s is available on request at any time. The protocol firmware is loadable. The serial interfaces can be run completely independent from each other. On every serial interface a different protocol driver can be loaded and run.
- For Windows as well as UNIX operating systems, the DF board compatible interface allows the replacement of an existing DF board by an SNL2-E Gateway without any changes in the application software.
- Hardware/driver installation with its typical related problems is no longer required
- Access to the SINEC-L1 interface from any network PC
- Trouble-free integration of lower automation levels into the control and design level
