Is it possible to get error messages using the RTDE interface? I was able to send messages using RTDE\_TEXT\_MESSAGE package, and the messages I sent appeared Log tab in the simulator. I wanted to know is it possible to retrieve the errors/ exception messages when some goes wrong (eg: robot goes to protective stop) using the RTDE\_TEXT\_MESSAGE or any other way using the RTDE interface.

@moliveira thanks for the reply. I also want to know the use of RTDE\_TEXT\_MESSAGE package, can we retrieve detailed error messages/ exceptions in this data package?
