SIMOTION supports PROFINET V2.2 according to the specifications of PI (PROFIBUS & PROFINET International) from Version V4.1 SP2 onwards

  • Entry
  • Associated product(s)

SIMOTION V4.1 SP2 supports PROFINET Standard, Version 2.2  across the board on all SIMOTION hardware platforms.

For the specification of PROFINET IO for IEC61158, there is a transition from Version V2.1 to V2.2. SIMOTION up to Version V4.1 SP1 and SINAMICS up to V2.5 SP1 HF9 support PROFINET communications corresponding to the PROFINET Standard in accordance with V2.1.

For the transition of the versions of the PROFINET Standard from V2.1 to V2.2, contents regarding PROFINET with IRT have changed. Operation in the RT class IRT in the PROFINET network is not compatible between Versions V2.1 and V2.2. This means that when using PROFINET with IRT together with SIMOTION and SINAMICS, then it should be carefully observed that the devices involved either all support the Standard according to V2.1 or V2.2 if they are involved in the IRT communication.

Presently, not all of the devices in the market support PROFINET with IRT according to V2.2, SIMOTION with V4.1 SP2  and SINAMICS S120 V2.6 SP1 (V2.5 SP1 with HF10) offer, in a transition phase, PROFINET to either be operated corresponding to the standard either in compliance with V2.1 or V2.2. Additional information on configuring and application cases is provided under the following file:

SIMOTION with the alternative PROFINET Version can be used for the SIMOTION platforms D425, D435, D445, D410 and P350.  SIMOTION C240 PN - as the new SIMOTION platform - will only support PROFINET V2.2.

Prerequisites:

  • Configuring
    To configure PROFINET communications according to V2.2, in addition to SIMOTION SCOUT V4.1 SP2   SIMATIC STEP 7 Version V5.4 SP4 is required.

Recommendation:

  • New machines/projects with SIMOTION and SINAMICS S120 based on PROFINET should generally be realized with PN V2.2.
