Thank you prakash for your response,
The CNC hardware is 720.2 with PLC 31-2DP.
The system is HMI EMBEDDED the HMI/NC version is Sinumerik 840D Sl CNC-software 331-5 with HMI-SL, 6-Language,software 2.5SP1HF1 on CF with license.
i read all the above document that you mention.
My question is there is any specific thing to do to enter the setup or commissioning mode for the integrated Prifibus S120.
I follow the sinumerik commissioning document [ IDsl] chapter 8 Commissioning integrated drives (NCU)
In Manual [ IDsl] , chapter 8.1.2 Automatic device configuration I can’t see [Alarm "120 402:...First commissioning of SINAMICS required!"]
In sheet 70 of document [ IDsl] After the complete drive system has powered-up, the HMI did not displays any information as it shown in page 70 titile3
I attached some screen form the machine
