Description
The EL6861 serial interface enables the connection of BACnet MS/TP devices (Master-Slave/Token-Passing) via an RS485 interface. Up to 32 MS/TP devices (up to 64 if ultra-low power transceivers are used) can be connected. Use the EL6861 interface only in combination with TwinCAT and CX9020 or higher, since the BACnet MS/TP driver integrated in TwinCAT implements the communication via the MS/TP protocol (BACnet Revision 12). The configuration is also done in TwinCAT.
