  The Los Alamos Neu­tron Sci­ence Cen­ter (LAN­SCE) con­trol sys­tem in­cludes many data chan­nels that are timed and fla­vored, i.e., users can spec­ify the species of beam and time within the beam pulse at which data are re­ported. The legacy LAN­SCE con­trol sys­tem ac­com-plished this task by queu­ing up ap­pli­ca­tion soft­ware-ini­ti­ated re­quests and sched­ul­ing Ana­log to Dig­i­tal Con-verter (ADC) read­out with cus­tom pro­gram­ma­ble time-de­lay gated and mul­ti­plexed Re­mote In­for­ma­tion and Con­trol Equip­ment (RICE). This year we up­graded this sys­tem to a new Ex­per­i­men­tal Physics and In­dus­trial Con­trol Sys­tem (EPICS) sys­tem that in­cludes sig­nal ded-icated wave­form dig­i­tizer. An ap­pro­pri­ate sub­set of the data is then re­turned as spec­i­fied by each client. This is made pos­si­ble by im­prove­ments to EPICS soft­ware, a Com­mer­cial Off-The-Shelf (COTS) Field Pro­gram­ma­ble Gate Array (FPGA) Mez­za­nine Card (FMC) based ADC and a COTS VPX FPGA card with EPICS em­bed­ded on a soft-core proces­sor. This year we up­graded over 1200 wave­form chan­nels from RICE to the new TDAQ (Timed/fla­vored Data Ac­qui­si­tion) sys­tem.
