Fieldbus, interfaces
JCOP Workshop November 2015

2. 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

3. 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?

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

5. 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

6. 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 November 2015

7. 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

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)?
