Hi, guys

I have a TIA portal V17 unified system with S7-1517F CPU

There is so many servo drive in my system

So Please let me know how many servo drive is available for IRT?

the other words, Maximum servo drive for IRT

and if IRT is not available, 

Is RT possible for servo drive ?

Best regards,

Lee

 Is RT possible for Servo drive?

and If It is possble,  what is different?

I mean....

for example,   if RT is used,   what is unusable function like synchronous control , motion control, so on?

In principle, servo drives should be able to operate without IRT, but you should check with the drive manufacturer.

However, using IRT will improve the quality of closed-loop position control. For example, you can find the following information in the function manual "STEP 7: S7-1500/S7-1500T Axis functions V7.0 as of STEP 7 V18":

PROFINET drives can always be operated in isochronous mode or clock synchronized mode. Isochronous mode, however, increases the quality of the closed loop position control of the drive and is therefore recommended for drives such as SINAMICS S120.

Kind regards
