Fieldbus Access runtime¶
Service management¶
Fieldbus Access runs as a service and the management is different depending on the system it runs on.
CC Linux 4.1¶
The runtime starts as a service and can be controlled by systemctl. Use either
enable or disable to control if Fieldbus Access should autostart or not:
sudo systemctl enable fieldbusaccess
sudo systemctl disable fieldbusaccess
The service may also be started or stopped while the system is running:
sudo systemctl start fieldbusaccess
sudo systemctl stop fieldbusaccess
Output from the service can be checked with journalctl:
sudo journalctl -fu fieldbusaccess
