6.3 Network operation
6.3.1 Basic principles
Purpose
The HMI devices can be connected to an Ethernet network. The MP 270B is equipped with
an on-board Ethernet interface. In the case of TP 270 or OP 270, an NE2000-compatible PC
card is required.
The network function can be used for the following:
• Logging data via the network
• Printing via a network printer
• Storing recipe data records in the network
• Exporting recipe data records from a network
• Importing recipe data records to a network
• Transferring projects
• Backing up data
Notice
The HMI device can only be implemented in TCP/IP networks.
The HMI device only has client functionality in the PC network. This means that users
can access files of a subscriber with TCP/IP server functionality from the HMI device via
the network. However, it is not possible to access files on the HMI device via the network
from a PC.
Note
Information on communication using SIMATIC S7 via Ethernet is provided in the "WinCC
flexible Communication" user manual.
Requirements
Within a TCP/IP network, computers are addressed by means of network names. These
network names are translated from a DNS or WINS server to TCP/IP addresses. Direct
addressing via TCP/IP addresses is not currently supported by the operating system.
Therefore, to ensure the functionality of the HMI device in a TCP/IP network, it is useful to
employ a DNS or WINS server. Appropriate servers are available in common TCP/IP
networks. Please contact your network administrator.
