Description

The SINUMERIK-Xplorer interface is suitable for measurement data acquisition from the NCK part (Numerical Control Kernel) of Siemens SINUMERIK CNC controls, incl. SINUMERIK One, via Ethernet using standard network cards as well as via Profibus using SIMATIC NET interface cards. Access is transparent for the SINUMERIK controller.

It is not necessary to specially configure or program it. The signals to be measured can be selected via the Sinumerik symbol browser in the I/O Manager of ibaPDA. NC data and SINAMICS servo symbols can be acquired in combination as well as symbols of multiple SINAMICS servo drives. Moreover, the SINUMERIK symbol browser supports user defined symbols ("GUD").

The connections to the SINUMERIK NCUs (Numerical Control Unit) can be established via standard interfaces of the computer or corresponding CP modules.

Additional Siemens software (e.g., SIMATIC NET or SIMATIC STEP 7) is needed for operation, in case the connection to the control system is established via a SIMATIC NET communication board (CP) in the computer to an integrated Ethernet interface of the CPU (if available) or to a CP module in the PLC.

Generally, no particular configuration and programming is required on the SINUMERIK side.

When using the PC/CP connection mode, a suitable access point must be configured in the SIMATIC PG/PC interface of the ibaPDA computer.
Interface settings

Set all values to zero when an NCK connection is lost.

If this option is enabled, all the measured values of an NCK are set to zero as soon as the connection is lost.

Start acquisition even if an NCK is not accessible.

If this option is enabled, the acquisition will start even if an NCK is not accessible. A warning is indicated in the validation dialog. If the system was started without a connection to the NCK, ibaPDA will periodically attempt to connect to the NCK.

Enabling this option is recommended if several connections to a CPU have been configured. As the SINUMERIK CPU is not able to start multiple connections at the same time, this allows the acquisition to be started without problems.

Allow inaccessible NCK variables

Enable this option to start the acquisition even if NCK variables are not accessible or if they are configured with an incorrect size. The inaccessible variables are displayed as a warning in the validation dialog.

Automatically restart ibaPDA server when NCK variable sizes automatically changed

If this option is enabled, the ibaPDA server is restarted automatically if the NCK variable sizes have changed automatically.

<Open log file>

If connections to NCKs have been established, all connection-specific actions are logged in a text file. Using this button, you can open and see this file. In the file system on the hard drive, you will find the log files in the program path of the ibaPDA server (…\ProgramData\iba\ibaPDA\Log\). The file name of the current log file is SINUMERIKLog.txt, the name of the archived log files is SINUMERIKLog_yyyy_mm_dd_hh_mm_ss.txt.

<Reset counter>

Resets the error counter as well as the response times in the connection table to zero.

Connection table

The table shows the error counters as well as the response times of the individual connections during data measurement.
