Release Announcement
PI Connector for Siemens SINUMERIK RPC is released

New Connector

OSIsoft is excited to announce the official release of PI Connector for Siemens SINUMERIK RPC.  This connector has been in private release for the last several months during which time it has been tested heavily and significant improvements made.


The PI Connector for Siemens SINUMERIK RPC allows monitoring of computer numeric control (CNC) machines that support the SINUMERIK RPC communication standard. Siemens SINUMERIK RPC is a library that can be embedded into software applications, allowing them to establish communication with SINUMERIK CNC machines via TCP/IP. The library includes a wide range of functions that provide access to process related information stored inside the CNC machines such as machine status information, PLC variables, program details, positional data and alarm number and time. PI Connector for Siemens SINUMERIK RPC incorporates the SINUMERIK RPC library as part of its communication operations and retrieves data from any CNC machines supporting this standard. The connector models a CNC machine by creating a PI AF hierarchy/structure in the PI Asset Framework, and PI points in the PI Data Archive.

This connector requires the PI Connector Relay (version 2.x) and Data Collection Manager, which are separate downloads.
