How does it benchmark against other modern PLCs? Could you give a ballpark figure for the scan time of a 10 robot cell for example?
If the question is about motion control of robots, our cycle time of 10-20 ms is probably too long as motion control usually requires < 1 ms.
If on the other hand the question is about human-robot collaboration safety, the product is likely unsuitable as this requires specially certified appliances.
If it's none of these two, it would be necessary to know more specifically what the setup is (fieldbus used, number of axes, etc) to come up with a realistic figure.
