7.7 Communication failure between PLC and controller
Description
The OmniCore controller and PLC are configured with all parameters correctly set.
However, the communication between the OmniCore controller and PLC still fails.
This issue may occur when the PROFIsafe-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 PLC,
the PROFIsafe device information must be configured on the OmniCore controller’s
side first. Otherwise, the configured signals will not be saved in the safety module
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.
For robots running RobotWare 7.5 or earlier, the following signals can be
observed.
