JCOP Workshop 04-05 November 2015 Fieldbus, interfaces JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces Current use of fieldbuses in experiments: Ethernet (e.g. Wiener LV PS, CAEN mainframe) CAN bus (e.g. Wiener VME, Iseg, ELMB) RS232/RS485 USB Profibus (e.g. PLC based applications) Other: GPIB, Parallel, propriety bus WorldFIP, one of the CERN standards, is not used in the experiments JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces Clearly the choice of the fieldbus is not completely free, it is bound to the device you want to control There is a trend to (or at least a demand for) Ethernet based communication with devices Point to point, or ‘bus’-like such as EtherCAT What is the longer term (beyond LS3) future of CAN bus? Anybody using EtherCAT devices? Anybody considering wireless? JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces What buses are likely to be used in the experiments? CANbus JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces Current use of fieldbus (CAN) interfaces in experiments: Kvaser PCI (original CANbus interface standard) Anyone still using these? Peak PCI or USB (CANbus interface for Iseg devices) Systec USB (current ‘de-facto’ standard) RS232 or USB ‘over Ethernet’ (e.g. Digi portserver and Digi USB anywhere) can add flexibility What is long term perspective of USB-CAN interfaces? LHCb sees no reason to change, others might consider change for Ethernet-CAN (LS2) EN/ICE support for systec will continue beyond LS2 Thanks to Geraldine Thomas for her input JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces New generation of interfaces Experiments expressed interest in Ethernet – CAN interfaces General interest in homogenizing the CAN hardware and software across CERN Survey and extensive validation tests performed by EN/ICE Newly supported and recommended solution: Anagate Tabletop boxes with 1/2/4 CAN ports 1U rack mounted with 12 CAN ports DIN rail mounted with 2/4/8 CAN ports Recommended solution for new developments Thanks to Geraldine Thomas for her input JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces Although support for current interfaces will continue, the recommended solution for new developments is the Anagate Ethernet - CAN gateway Keen interest by experiments (CMS); what is the operational experience? CMS aims to replace all SYSTEC interfaces by Anagate gateways in the coming months Thanks to Geraldine Thomas for her input JCOP Workshop 04-05 November 2015

JCOP Workshop 04-05 November 2015 Fieldbus, interfaces Questions: What buses are likely to be used in the experiments? What is the longer term (beyond LS3) future of CAN bus? Can we converge to a common standard? Anybody using EtherCAT devices? Anybody considering wireless? What is longer term perspective of USB-CAN interfaces? What is the operational experience with Ethernet-CAN interfaces (anagate)? JCOP Workshop 04-05 November 2015
