Problem
There is a communication problem between a Robotiq gripper and a TM/Omron robot.
The problem can be just a delay or a request not working (grip check, position...)
On TM/Omron, the latency below 3 seconds, can be a normal situation. This is mostly due to the time for communication using the converter RS232.
The occurrence of the delay may happen 1 out of 800 times or more.
Troubleshooting
1. Verify the version of TM Flow.
2. Verify the version of the Robotiq component.
3. Verify the version of the RS232-RS485 adapter.

How to test
Make a small program where the gripper opens and closes and monitor it.
You can include a grip check feature.
Solution
1. Update TM Flow to the latest compatible version.
2. Update the Robotiq component to the latest compatible version.
3. Replace the RS232-RS485 adapter.
4. Try with a different adapter but make sure the new one is from the correct version.
5. Try a different gripper, coupling, and cable.
6. If all still fails, contact the Robotiq support team (support@robotiq.com) and provide the necessary information.
