Virtual Serial COM Driver

By using a software supplement under TwinCAT in conjunction with an EL60x1 EtherCAT Terminal a serial

interface can be positioned in the I/O ﬁeld of a system at a signiﬁcantly further distance from the controller

than would be possible with a cable-based physical layer (RS232/RS422/RS485).

Basic Principles

The TwinCAT Supplement Virtual Serial COM Driver in combination with a serial EL6001 (RS232) or EL6021 (RS422/RS485)

interface terminal for the EtherCAT I/O system enables virtual COM interfaces to be generated that can be used by Windows

applications just like normal serial interfaces. The actual connection point for devices with serial interface can be anywhere in

the ﬁeld (see Fig. 1). In order to use such third-party devices with serial connection in the ﬁeld, in the past a PC with a suitable

interface had to be installed in the ﬁeld or a connection between the interface and the central controller had to be established

using a suitably long cable. A PC generates additional costs for acquisition and system integration. The cable length is limited

by the corresponding physical layer. A Windows-compliant serial interface can be set up in the PC by using the EL60x1

EtherCAT Terminal and the TwinCAT Virtual Serial COM Driver.
