	We had useful discussion about DVCS Trigger System. ~~First revision of document containing requirements was placed on~~ http://clonweb/wiki/index.php/DVCS_Trigger_System along with related materials. We talked about general design, necessity of external start signal to start DVCS Trigger logic, the source of that start signal (L1 or self), outputs we want to have. Ben expressed an opinion that project can be completed using v1495 boards, he will look closely on the project. We'll have another discussion soon to finalize system design.		We had useful discussion about DVCS Trigger System. New page http://clonweb/wiki/index.php/DVCS_Trigger_System was created. It contains system requirements along with related materials, and will be updated regularly by adding new materials and updating existing ones. We talked about general design, necessity of external start signal to start DVCS Trigger logic, the source of that start signal (L1 or self), outputs we want to have. Ben expressed an opinion that project can be completed using v1495 boards, he will look closely on the project. We'll have another discussion soon to finalize system design.

	~~We discussed ioc restart procedure and decided to add~~ '~~ioc reboot~~' ~~button to existing ioc reboot GUI, so it can be done by~~ '~~clasrun~~'~~. Currently it can be done by~~ '~~root~~' ~~or by designated users included into 'sudo' list. Along with reboot function it will be good to have heartbeat as well, same way as for vxworks iocs.~~		'''Projects'''

	~~Several repair-related issues were discussed~~. ~~Three Lecroy mainframes were sent tfor repair~~, all ~~of them were repaired recently, we hope to repair it for free~~. ~~One more mainframe will go to repair for the first time. All~~ mainframes in the ~~Hall B are working but we do not have any spares right now~~.		Nerses reported progress on epics support for the SY1527 system. He finished driver modification, all available boards are supported now. Three mainframes (HVDVCS, HVTEST and PCAL) are running fine with the recent version of driver.

	~~CAEN 1533 6-channel HV board have a problem enabling last 3 channels, we~~ be sent to ~~CAEN~~.		Softioc startup script was modified by Nerses: instead of using 'sleep' as ioc input Nerses decided to use 'pipe' named 'softioc.pipe' created in the same directory where ioc config file is located. Command 'exit' can be sent to that pipe to force ioc to exit (actually any command forces ioc to exit).

	~~PCAL fastbus crate lost +5V power~~, ~~will~~ be ~~repaired on site~~. ~~In general PCAL test setup works, but several issues remains,~~ will be ~~investigated~~.		We discussed ioc restart procedure and decided to add 'ioc reboot' button to existing ioc reboot GUI, so ioc can be rebooted by user 'clasrun'.

	~~We attempt to take laser data from CLAS TOF system~~, ~~several problems~~ were ~~observed including readout~~, will be ~~addressed~~.		Several repair-related issues were discussed. Three Lecroy mainframes were sent for repair, all of them were repaired before, so we hope that those mainframes will be repaired for free. One more mainframe will go to repair for the first time.

	This morning we experienced power outage in counting house because of emergency generator panel repair. It is probably make sense to ask for better power management: when emergency generator is on service, normal power should be supplied. Sergey will submit request.
