Issue Details

The Modbus registers update slowly in Vision Builder for Automated Inspection (VBAI), how can I increase the refresh rate?

Solution

You can modify the loop rate by adding the following section to the Vision Builder AI System Config.ini located in the /etc/natinst/vbai/ folder:

[PrivateDeviceSettings]
Server_PrivLoopRate = <period in ms> 

The Vision Builder AI Modbus server is set to update Modbus registers at an appropriate rate for the target.
