WAGO-I/O-SYSTEM 750 System Description
2.1.1.7 Functional description
The interface module is designed to operate with all WAGO I/O fieldbus
couplers. The TTY interface module allows the connection of TTY-Interface
devices to the WAGO I/O SYSTEM. The TTY 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 128 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.
