Security Application Diagram
Integrated Security PLC-based SCADA Wireless Multi-site Network
Any existing PLC application using a wireless link to remote sites connected to other PLC and I/O equipment are now able to add security devices at the remote site by using the existing communication path.
An existing corporate Ethernet network at any industrial plant can be used with security software to access the devices that have been added at the remote sites without changing the configuration of the entire system.
At Site 1 a video application consisting of a video camera and a video server have been added to an Ethernet switch. This now allows monitoring of that remote site or process via the exiting Ethernet link. The same security equipment could be done at Site 2.
Site 3 shows a new remote site that was added by using a Data-Linc wireless Ethernet modem to the existing wireless Ethernet network. A site like water reservoirs, gate control, etc. might require a complete security application consisting of a motion detector, camera and security I/Os.
