Benefits
Industrial security documentation contains recommendations and information for the planning
and design of secure systems or plants. The documentation serves as a reference material and
guideline. It is not a requirement.
The intent of the documentation is to support customers in safely operating their controls or
plants. The operator is responsible for implementing the security recommendations.
9.4.4
Parameter Security Levels
The SINAMICS Perfect Harmony GH180 provides for security levels for parameter changes. These
security levels are not meant for more than simple protection of inadvertent access to
parameters based upon the sophistication of the maintenance being performed. These security
levels are 0, 5, and 7.
The SINAMICS Perfect Harmony GH180 control allows the user to perform the following:
• Change the security access code
• Set the security level for parameters
• Enable / disable the ability to change parameters while the drive is in operation
9.4.5
Write Protection
The GH180 drive contains a piece of software called a System Operating Program (SOP). This
system operating program can be modified such that parameter writing cannot occur. This SOP
can be programmed such that a specific digital input, network flag and or operating conditions
must be present to allow keypad parameter modification. Once set, this write protection
parameter also prevents selection of a new SOP via the keypad and also prevents parameter
modification via the ToolSuite drive tool. Otherwise, the internal system memory will need to be
recovered using the section USB Connection/Secure USB System Keys.
Note
Ensure that the SOP-based write protection can be turned off.
Otherwise, the internal system memory will need to be recovered using the section USB
Connection/Secure USB System Keys.
9.4.6
Network Protection
The SINAMICS Perfect Harmony GH180 drive supports three networks, two of which are field bus
networks. The third network is reserved for future use.
