2.3 Important Information Regarding Decommissioning Of The Module - Siemens SIMATIC S7-1500 Manual

Locking the Ethernet port
Lock the unused Ethernet port mechanically with an RJ 45 port lock.
Diagnostic message when the SIMATIC Memory Card is removed
Removing the SIMATIC Memory Card during operation triggers a diagnostic event, which is
indicated in the value status (error byte, bit 1) in the PII.
You can find more information in section: Status and error information in the process image
input (PII) (Page 28)
Preventing loss of data on the SIMATIC Memory Card
Routinely create backup copies of the contents of the SIMATIC Memory Card, e.g. neural
networks, apps/scripts and configuration files.
In this way, you protect your know-how from tampering or stolen SIMATIC Memory Cards.
Disabling debug mode via web server during operation
If the module has been enabled for commissioning, then ensure that debug mode via web
server has been disabled during module operation. This prevents unauthorized access and
thus the reading of potentially confidential diagnostic information (MicroPython debug
information).
You disable the web server through configuration in HW Config. Default state of the web
server: disabled.
To prevent it from being enabled (again) without permission, also delete the configuration
file debug.conf (Page 59) from the SIMATIC Memory Card after commissioning.
2.3 Important information regarding decommissioning of the
module
When you decommission the TM NPU, remove the SIMATIC Memory Card. In this way, you
prevent improper access to your data.
