Functional description

The interface module is designed to operate with all WAGO I/O fieldbus
couplers. The serial interface module allows the connection of RS485 or
RS488-Interface devices to the WAGO I/O SYSTEM. The RS485/RS488
Interface module can provide gateways within the fieldbus protocol. This
allows serial equipment such as printers, barcode readers, and links to local
operator interfaces to communicate directly by the fieldbus protocol with the
PLC or PC Master. This module supports no higher level of protocol.
Communication is made completely transparent to the fieldbus allowing
flexibility in further applications of the serial interface module. The
communication protocols are configured at the Master PLC or PC.
The 120 byte input buffer provides for high rates of data transmission. When
using lower rates of transmission speed you can collect the received data, with
less priority, without loosing data.
The 16 byte output buffer provides for faster transmission of larger data
strings.
The data transmission takes place at 9,600 baud (default value). 1 startbit, 8
databits and 1 stopbit will be transmitted. No parity is available. The drivers
are high ohmic. The control of data is made by the user software.
