Service installation

/usr/local/plc/bin/plc_service_install <service name>

This command will install and start a new system service. If the program has the same name as the service, is in /usr/local/plc/bin/ directory and doesn't take any command line options, no other configuration is needed.

Service uninstallation

/usr/local/plc/bin/plc_service_uninstall <service name>

This command stops and uninstalls given PLC service.

Service list

/usr/local/plc/bin/plc_service_list [-s]

List all installed PLC services. -s option also shows their status.

1. /usr/local/plc/etc/service/<name>.cfg
2. /usr/local/plc/etc/service/<name>
3. /usr/local/plc/etc/<name>.service.cfg
4. /usr/local/plc/etc/<name>
