Can RMC150E support Profinet IRT Function?

Can RMC150E support Profinet IRT Function?

No, just standard Profinet.
What function do you need that is provided by Profinet IRT that can’t be accomplished by the RMC150E using Profinet?

So far no.
I just have such a question.

Synchronous field bus systems like Sercos, ProfiNet IRT and CIP motion have their place but not in applications
where the actuators need to be tightly coupled to another actuator. Many such applications are hydraulic applications
such as presses and veneer lathes or any similar applications where actuators opposed each other
and one is in pressure or force mode and the other in position mode. In these cases the actuator in force mode must
know how the master is moving immediately so that feed forwards can be applied. The bus systems are not setup
to handle these common hydraulic applications where the master must read one actuator to make a decision about what to do with another actuator.
There are too many communication delays and the scans may be asynchronous. It is best if the motion control is handled all within one module.

As for speed. Look at this. … 20mode.mp4
There is no way bus system can transfer information from the position feed back from the dart to
the PLC then tell the balloon motor to move in time. There are too many communication delays. The calculations are too difficult for a PLC anyway.
Notice that there is a RMC75 there by the persons right shoulder. The balloon must start moving away from dart as it approaches.
The position, velocity and acceleration must be matched at contact. One big advantage the RMCs have is that which ever actuator is
the master executed first within out scan so the data can be used to make calculations for the slave axis in the same scan.
There are no communication delays.
This was programmed by our engineer in Washington State and Temposonics is in North Carolina across the country.
This was used for the Temposonics balloon demo
In both cases the dark moves up to the balloon and touches it but never depresses the balloon enough to pop it.
How can a bus based system read the dart position, to computations and then send the data back to the balloon position quickly?

When a salesman tells you a field bus type of communication system is good ask them if they can do what you see in the video.

Some day we will probably support a synchronous field bus like EtherCat but it can’t possibly match the performance you see in the videos.
The advantage that a synchronous field bus system has is that axes can be added easily and each axis has its own CPU to off load the master.
