Lukasz Zwalinski GUAPI 26 th June 2013 We have selected to work with Schneider PLCs We knew that PROFIBUS is not perfect solution for Schneider Schneider strongly advertised Ethernet IP (FDT/DTM workshops etc.) EN-ICE recommended to study this technology More and more equipment available with Ethernet IP Selected WAGO as I/O solution FESTO as electro valves Why Ethernet IP? Ethernet IP advantages Siemens and Schneider goes in the direction of implementation of the industrial Ethernet Transparency: configure, control and diagnose all devices on the network Efficiency: consolidate control onto a single network module Simplicity: manage the entire network with Unity Pro Ring topology Hot Swapping Etc.. But is it real??

CMS real implementation Lukasz Zwalinski GUAPI 26 th June 2013

CERN TN – Ethernet IP was not validated to be implemented in CERN TN network directly, as the consequence we don’t have the direct access to all the devices in the network UNITY PRO - Each PC from which we want to access our application should have the same DTM library, so we need to import the definition files on all our PCs independently Addressing Implementation issues We have to remember that declared memory area for the Ethernet IP communication is not covering with UNICOS mapping Lukasz Zwalinski GUAPI 26 th June 2013

Addressing - to establish no error communication the declared memory addressing for the coupler has to match exactly the real memory consumed by the coupler. Implementation issues Trick for WAGO Calculated memory area for inputs has to be always increased by 1 byte!! As it is reserved for coupler identification. User has to carefully calculated required memory or can connect to the device and read how much it consumes. (Online parameters in Ethernet IP) Lukasz Zwalinski GUAPI 26 th June 2013

Addressing – is not an issue when You use Schneider equipment like STB_NIC2212 When additional Advantys software installed for configuration of the Schneider Ethernet IP device it connects automatically with UNITY and it has very nice graphical representation of the hardware configuration Implementation issues Lukasz Zwalinski GUAPI 26 th June 2013

Summary Summary: Ethernet IP is very interesting technology but at CERN currently we can not use all features because of the network infrastructure. It does not allow in reality to access to the device form our PC like in example Siemens PDM. We need to connect into privet network. Advantages: Ring topology – verified Hot swapping – not verified Consolidation – verified Easy cabling Lukasz Zwalinski GUAPI 26 th June 2013
