MS Reporting Services are included as part of MS SQL.
Q: What product specific interface does the product have iro well-known MES packages?
Interfaces are available for most known MES systems such as SAP.
PLC configuration and programming
Q: What capabilities does the scada offer in terms of generation and/or management of PLC configuration files or PLC application code?
WinCC integrates fully with Simatic Manager (Step 7 for the Siemens PLC). Tags are directly available and alarming is automatically generated during compile.
Security and data protection
Q: If the scada system generates application files that are transferred to the PLC, how are Stuxnet style PLC virus attacks prevented?
The scada system does not generate application files, only Simatic Manager does that. Stuxnet was a very specific virus for a very specific application. Preventative measures have been taken to prevent future problems.
Q: What authentication, authorisation & role management models are available for the runtime environment?
Incorporated in the application based on the Windows Authentication system.
Unique selling proposition (USP)
Q: List the top five feature/benefit pairs that contribute to this product’s USP.
