Hello,

the XB Switch is not a PROFINET IRT Switch, so it can not be configured between two IRT devices .

Hello,

normally S210 is running with DSC and Telegram 105. For this IRT is required.

With RT you get a worse control behavior.  Use a HUB with IRT!!

If not possible, please do " One Bitton Tuning" with Mode  "conservative" and use a setpoint filter.

Available with V5.2

Speed setpoint filter for PN-RT
The speed setpoint filter in conjunction with Profinet RT (S7-1200) improves the running characteristics of the motor. The speed setpoint filter is activated with a time constant greater than zero. The time constant for the speed reference filter (PT1) is set via p1416[0].

Dear Sir,

 Thanks of your reply.

Because i do not have so many knowledge of drives, i use V90 and S210 of IRT in my every projects.

At that time , i use Technology objects.

But this time I will use "SINA_POS" Siemens Blocks to control the drives(V90 and S210).

In this post, i can find some information of these two stuff.

But when should i use SINA_POS? when should i use Technology objects?

I still can not have a very good concept...

Sorry of my Poor english.

Hello,

in fact, the SINAMICS S210 does not have an integrated positioning function. You should use all time the technology objects for SINAMICS S210.

To have the full performance of a SINAMICS S210 drive system, we recommend using telegram 105 IRT. Further details can also be found in the FAQ below:
