  1. 1. News from TPC DCS cooling prototype • Project overview: • Aim of the prototype: investigating and developing standard DCS solutions • and integrating them in the TPC community • 1-st version of the cooling prototype(IROC) was assembled in april 2001, • in 161-R024 • had as main features the cooling mechanical structure very similar to • the final version • control loop was consisting in monitoring the temperature and controlling • the input current for heater.

  7. In progress : Step 1 qualification of Wago mPLC (in thermolab) consisting in: -test of system stability -test of system load (maximum nr. PID loops) -test of time response with a maximum load Step 2 studies of other possible solutions : ELMB (the Atlas Embedded Local Monitoring Board) The same type of tests will be performed in the next weeks PT1000 adaptators , software + connection to sensors finished and working properly Alice DCS workshop S.Popescu

  8. Near future: Step 3 Qualification of new electronics board (FEC), aim  control of LV full cable length Wiener PL500 + Slic.OPC + Control Panel September  161-R024 Implications on control side: - test of archiving, alarms and database handling Step 4 Test of cooling for IROC + electronics (45 FEC) October  TPC laboratory Step 5 Test for a complete control for 1 IROC: cooling, LV Wiener PS, FEC, HV Iseg PS news : Iseg OPC sever exist and is working good Alice DCS workshop S.Popescu
