Serial interface RS422/RS485
| Information | |
| About product | The EL6021 serial interface enables the connection of devices with RS422 or RS485 interface. These devices communicate with the automation device via the coupler. The active communication channel operates independently of the higher-level bus system in full or half duplex mode at up to 115.2 kbaud. The transmission of differential signals according to RS422 guarantees high immunity to interference through electrically isolated signals. In conjunction with the TwinCAT Virtual Serial COM Driver (see TwinCAT Supplements – Communication) the EL6021 can be used as a normal Windows COM interface.The EL6021 serial interface enables the connection of devices with RS422 or RS485 interface.
