7.8 Communication failure between scalable I/O device and controller
Description
The OmniCore controller and scalable I/O device DSQC1042 are configured with
all parameters correctly set. However, the communication between the OmniCore
controller and scalable I/O device still fails.
This issue may occur when the SafetyIO-based laser scanner(s) is connected.
Consequence
The safety configurations do not take effect.
Possible causes
During configuration of communication between the OmniCore controller and
scalable I/O device, the scalable I/O device information must be configured on the
OmniCore controller’s side first. Otherwise, the configured signals will not be saved
in the OmniCore controller.
Recommended actions
1 Open the RobotStudio.
2 In the Controller tab page, choose Visual SafeMove from Safety in the
Configuration group.
3 Check the Safe I/O configurations.
The following signals can be observed.

4 If the signals cannot be observed, choose I/O Engineering Tool from
Configuration in the Configuration group.
5 Go back to the Visual SafeMove window and write the SafeMove
configurations to the controller again.
You will observe the signals and the communication is correctly set up.
