Configuration Files; Network.conf - Siemens SIMATIC S7-1500 Manual

Configuration files

Inconsistent entries and errors in the network.conf, ftpclient.conf and debug.conf
configuration files are reported via a group error in the PII.
You can find more information on the process image input (PII) in the value status (error

network.conf

NOTE
The configuration file "network.conf" is required for use of the TM NPU. The file must be
present with valid entries in the "/config" folder on the SIMATIC Memory Card, even if the
Ethernet port is disabled and not being used. Otherwise, the module does not start.
The configuration file "network.conf" is only read during startup of the TM NPU. The IP
address of the TM NPU is specified in the configuration.
Structure of the configuration file
The configuration file "network.conf" contains the following information:
• address
• mtu
Supported character sets: UTF-8, CP1252
Permitted line endings: LF (Unix)
Procedure
1. Create or edit the configuration file "network.conf".
2. Copy the configuration file "network.conf" to the "/config" folder on the
SIMATIC Memory Card.
The Ethernet connection is only established if the configuration file "network.conf" is
present on the SIMATIC Memory Card.
Changes to the configuration file "network.conf" only take effect after a restart of the
TM NPU.

// IP address of the TM NPU and the subnet mask as short notation
