The LAN-RING industrial switch software package includes the Extension suite, a set of advanced tools for managing available I/O and RS-485 buses. Users can configure up to 64 automatic actions here. A major advantage is the switches’ ability to communicate directly with the IPLOG PLC. This runs a control programme written in FBD, LD, ST or IL languages in accordance with the IEC 61131-3 standard.

Thanks to these capabilities, the LAN-RING system offers significantly greater utility. Users can precisely tailor the device’s functionality to the specific requirements of a particular project and effectively optimise the operation of the entire network.

Examples of practical uses for automatic actions

The Extension menu allows you to easily configure automatic responses. In its simplest form, this involves a direct link between an input and an output. In practice, you can use the system, for example, to:

  • Enhancing security: Rotating a PTZ camera to a predefined position if a switchboard tamper is triggered or when motion is detected by a PIR sensor.

  • Network diagnostics: Signalling the connection or disconnection of an optical ring via a relay output.

  • Energy saving and power supply protection: Automatically switching off the PoE power supply if the charge level of the backup batteries falls below 30 per cent.

  • Integration with CCTV systems: Reception of TCP events generated by advanced video analysis within the camera and their subsequent mapping to a relay output.

  • Ensuring high availability (IP Watchdog): Automatic restart of the camera’s power supply should the device cease to respond to ARP queries.
