2. Introduction • Scalance Siemens Alternatives • STMS – Surface Temperature Monitor Surveillance IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

3. Scalance Siemens Alternatives • Objective: split the PLC sub-network from the main RFQ network and manage traffic between them. • Product available form Siemens Catalogue: • Scalance Siemens (Switch Industrial Ethernet Scalance) • Features: • realize industrial electric/optic ethernet network [linear or star configurations] • flexible port configuration and traffic management • diagnostic tools available • cost: about €1000,00 IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

4. Scalance Siemens Alternatives • Alternative found: OPNwall rack edition - 19" m0n0wall appliance • Features: • complete embedded fan-less firewall appliance • software: Linux M0n0wall firewall • it can be used as Wireless Access Point IPsec VPN gateway, Captive portal and Traffic Shaper. • provides skill desired (packet filtering with block/pass rules and logging) • cost: €349,00 IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

5. STMS – Surface Temperature Monitor Surveillance • Task: Monitor RFQ’s Surface Temperature through dedicated distributed devices • Hardware chosen: 1-wire system • 1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. It is typically used to communicate with small inexpensive devices such as digital thermometers and weather instruments. • Temperature Sensor: 1-wire digital thermometer [DS18B20] • Network Interface: LinkHub-E ethernet interface IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

6. STMS – Surface Temperature Monitor Surveillance • 1-Wire sensor network configurations • There are different configuration available for realize the sensor network. • Examples: • Now it is possible to create a 1-line sensor network (available for testing 1 LinkHub and 4 Digital Thermometers) IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

7. STMS – Surface Temperature Monitor Surveillance • Software: • there are different open source software available to realize a distributed monitor system with 1-wire hardware. • main objective: integrate 1-wire solution into the EPICS Environment • Possibly solutions: • create an EPICS driver to manage data acquisition from the LinkHub • use 1-wire software into the EPICS Control System Environment IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012

8. STMS – Surface Temperature Monitor Surveillance • Possibly solutions: • create an EPICS driver to manage data acquisition from the LinkHub EPICS Asyn + StreamDevice Support for TCP Connections IFMIF-EVEDA –INFN Legnaro LCS – Monthly Collaboration Meeting, Legnaro, March 02, 2012
