Experiment Control System
LS1 Plans…
Clara Gaspar, November 2012
ECS Infrastructure❚Current Control PCs are old, so:
❙New, more powerful machines❘Virtual machines x group projects
❙New Operating Systems:❘Windows 2008S-R2 64 bits only❘Linux SLC6 64 bits only
❙New WinCC-OA 3.11❘No more PVSS…
➨ Need to “move” and “upgrade” ALL PVSS projects

ECS Interfaces❚Effects on Hardware Interfaces
❙PCI slots no longer available❘SPECS -> New ethernet based SPECS
(coming…)❘Peak CAN Interface -> ?
❙Virtual Machines -> no direct HW connections❘Systec CAN-USB (direct USB cables)
-> New box USB to ethernet (under discussion)
❘Ethernet: Ok
❙Other Hardware?

❚ Preliminary…
❚ Run Specs Server in CCPC❚ PVSS Project in Control PC

❚ Simplified block diagram - Preliminary…
❚ Use PVSS “Scattered” Systems:❚ Run OPC Server & PVSS OPC Client in each CCPC❚ PVSS Project away on Control PC
Clara Gaspar, November 2012
ECS Interfaces❚Effects on Hardware Interfaces
❙In general for HW access from virtual machines:❙Separate the HW access & the supervisory
layer➨ By making more use of scattered projects /
distributed DIM Servers…
❙Software: New 64 bit OSs:❘New drivers (SPECS, Systec)❘New OPC Servers:
〡CAEN, WIENER, ISEG, ELMB
➨ Working versions exist

WinCC-OA 3.11❚Siemens Strategy:
❙Base all their SCADA products on the PVSS core (i.e. Event Manager,Data Manager, etc.)❘Simatic WinCC (Their old product)❘Simatic WinCC Open Architecture (old PVSS)
❚Implications:❙Installation directory changes❙Manager names change
❘WCCILpmon, WCCILevent, etc.❘WCCOActrl, WCCOAui, etc.

WinCC-OA 3.11❚Implications (continued):
❙New JCOP framework:❘All CERN managers re-built:
〡WCCOAdim, WCCOAdip, WCCOAsmi, etc.
❙Luckily stay the same:❘The Project directory structure❘All functions used in Ctrl scripts and User
Interfaces❘The C++ API for managers and ctrl extensions
❙In general: everything still works!(and we can mix projects of different versions)

WinCC-OA 3.11❚Improvements
❙Several, reported here:❘ http://www.etm.at/index_e.asp?id=&sb1=&sb2=&sb3=&snam
e=div_nw_0212_3_11_e.asp&sid=&seite_id=
❘They claim better performance…❘Otherwise I found nothing really useful for
us…
❚But we need to install it:❙Because we need the support for the new
PCs, operating systems, 64 bits, etc.

Migration Strategy❚Procedure (draft):
❙Keep the old PCs up.❙Copy project to new machine❙“Upgrade” Project❙Test project➨ We will try to create tools to ease the
procedure and of course document the exact detailed procedure to follow.

To be done by Sub-system Teams

Migration Strategy (detail)
❚Current plan:❙Old PCs will be renamed prefix with “old”
❘ Ex.: r2dcs02w (running Windows 2003 SP2, PVSS 3.8 SP2) r2dcs02w (running Windows 2008 SP2, WinCC 3.11) old PC will be kept as oldr2dcs02w
❘ Auto-start of DIM and PVSS will be disabled
❙New PC with the same name and new OS prepared
❘ New WinCC installed, all configurations, privileges etc. ported over (to the extent possible)
❘ Projects will also be copied over
❙New and old computers can run in parallel, but the WinCC projects and some DIM stuff can not!
❘ This allows manual going forth and back in case there is a need to check

Migration Strategy❚“Details” to be sorted out:
❙“PVSS” Archive❘WinCC-OA 3.11 needs a new schema version
(Once upgraded old project can not use archive anymore)
➨ Clone archive?
❙Project Upgrade x Project Recreation❘Projects seem to “age” (get heavier and
slower)➨ Create new ones and (ascii) import all
dps?
❙Projects in PCs with HW (Specs for ex.)❘If HW replacement not available yet➨ Leave DIM/OPC Server there, migrate
project

Manpower & Responsibility
❚Each sub-system:❙Is responsible for upgrading and testing
their projects (there will be docs and tools)
❙Should give us their preferred schedule, so that we can give support…
❙Can give us comments and requests for (central) improvements, we are open…
❙Can discuss with us all other upgrades in their sub-systems, we would like to help…

Conclusion❚No PVSS projects after LS1…
❚We need your collaboration…
