The IP services, FTP server, and service terminal, reside in the local
data acquisition system. The benefits of using a serial line IP connection
in this kind of configuration are:
- Standard file transfer method
- Possibility to establish multiple simultaneous links over one serial
line
1. Configure the PPP connection in the local data acquisition system
with the parameters presented in
Table 69 on page 320 . Further
information on creating dial-up/in interfaces in Windows PCs and
configuring their parameters can be found in Windows online help.
2. Add and configure the physical communication devices in the
setup.
a. In the Optional hardware view, add module DSU232 to an
available module place.
b. In the Devices view, add the device WinNullModem-IP.
NOTE Half-duplex links, such as two-wire RS-485, are not suitable as PPP
carriers with the QML logger. Whenever possible, using Ethernet
should be preferred.
