  Sys­tem on a chip (SoC) is widely used in em­bed­ded en­vi­ron­ment. Cur­rent gen­er­a­tion SoC com­mer­cial prod­ucts with small foot­print and low-cost have pow­er­ful in CPU per­for­mance and rich in­ter­face so­lu­tion to sup­port many con­trol ap­pli­ca­tions. To deal with some em­bed­ded con­trol ap­pli­ca­tions, the "Ba­nana Pi" which is a card-size sin­gle-board com­puter and runs Linux-based op­er­a­tion sys­tem has been adopted as the EPICS IOC to im­ple­ment sev­eral ap­pli­ca­tions. The ef­forts for im­ple­ment­ing are sum­ma­rized in this paper.

  For a low emit­tance light source, beam orbit mo­tion needs to be con­trolled within sub­mi­cron for ob­tain­ing a high qual­ity light. Mag­nets vi­bra­tion es­pe­cially quadru­ples will be one of the main sources to de­stroy the beam sta­bil­ity. In order to study the re­la­tion­ship be­tween vi­bra­tion and beam mo­tion, it is highly de­sir­able to use a syn­chro­nous data ac­qui­si­tion sys­tem which in­te­grates mea­sure­ment of vi­bra­tion and beam po­si­tion mon­i­tor sys­tems es­pe­cially for the co­her­ence analy­sis. For a larger vi­bra­tion such as earth­quakes are also dele­te­ri­ous to beam sta­bil­ity or even make the beam trip due to the quench of su­per­con­duct­ing RF cav­ity. A data ac­qui­si­tion sys­tem in­te­grated with an earth­quake de­tec­tor is also quite nec­es­sary to show and archive the data on the con­trol sys­tem. The data ac­qui­si­tion sys­tems of vi­bra­tion and earth­quake mea­sure­ment sys­tem are sum­ma­rized in this re­port. The re­la­tion­ship be­tween the beam mo­tion and mag­nets vi­bra­tion will also study here.

  The con­trol sys­tem had been es­tab­lished for the new 3 GeV syn­chro­tron light source (Tai­wan Pho­ton Source, TPS) which was suc­cess­ful to com­mis­sion at De­cem­ber 2014. Var­i­ous con­trol sys­tem plat­forms with the EPICS frame­work had been im­ple­mented and com­mis­sioned. The re­la­tional data­base (RDB) has been set up for some of the TPS con­trol sys­tem ap­pli­ca­tions used. The EPICS data archive sys­tems are nec­es­sary to be built to record var­i­ous ma­chine pa­ra­me­ters and sta­tus in­for­ma­tion into the RDB for long time log­ging. The spe­cific ap­pli­ca­tions have been de­vel­oped to an­a­lyze the archived data which re­trieved from the RDB. One EPICS alarm sys­tem is nec­es­sary to be set up to mon­i­tor sub-sys­tem sta­tus and record de­tail in­for­ma­tion into the RDB if the prob­lem hap­pened. Some Web-based ap­pli­ca­tions with RDB have been grad­u­ally cre­ated to show the TPS ma­chine sta­tus re­lated in­for­ma­tion. The ef­forts are de­scribed at this paper.

  Con­trol sys­tem for the Tai­wan Pho­ton Source (TPS) has been com­pleted in 2014. Com­mis­sion­ing of the ac­cel­er­a­tor sys­tem is in pro­ceed­ing. Elec­tron beam were stored at the stor­age ring and emit first light in De­cem­ber 31, 2014. TPS con­trol sys­tem adopts EPICS toolk­its as its frame­works. The sub­sys­tems con­trol in­ter­faces in­clude event based tim­ing sys­tem, Eth­er­net based power sup­ply con­trol, cor­rec­tor power sup­ply con­trol, PLC-based pulse mag­net power sup­ply con­trol and ma­chine pro­tec­tion sys­tem, in­ser­tion de­vices mo­tion con­trol sys­tem, var­i­ous di­ag­nos­tics re­lated con­trol en­vi­ron­ment, and etc. The stan­dard hard­ware com­po­nents had been in­stalled and in­te­grated, and the var­i­ous IOCs (Input Out­put Con­troller) had been im­ple­mented as var­i­ous sub­sys­tems con­trol plat­forms. Low level and high level hard­ware and soft­ware are tested in­ten­sively in 2014 and final re­vise to pre­pare for rou­tine op­er­a­tion is under way. Ef­forts will be sum­ma­rized at this paper.
