  From time-to-time, mi­cro­con­troller- and FP­GA-based LLRF elec­tron­ics de­vices need main­te­nance of firmware and con­fig­u­ra­tion data. The sys­tem de­scribed here al­lows this and also long term mon­i­tor­ing of func­tion­al­i­ty and per­for­mance. Both re­quire­ments cover mea­sur­ing de­vices that op­er­ate under a com­mon op­er­at­ing sys­tem as well as mod­ules only ad­dress­able by means of GPIOs or their pro­gram­ming in­ter­face. For large ac­cel­er­a­tor sys­tems like in the FAIR pro­ject, a Web-based re­mote­ly con­trolled sys­tem was de­signed in close col­lab­o­ra­tion with two in­dus­tri­al part­ners. To cover the re­quire­ments of the ex­treme­ly dif­fer­ent types of par­tic­i­pat­ing mod­ules while re­main­ing flex­i­ble for fu­ture ex­ten­sions, the sys­tem was de­signed with a max­i­mum of mod­u­lar­i­ty and a strong focus on high re­li­a­bil­i­ty and safe­ty. This con­tri­bu­tion de­scribes the glob­al struc­ture and the ac­tu­al sta­tus of the RF Main­te­nance and Di­ag­nos­tics Sys­tem. Sev­er­al types of mea­sur­ing equip­ment and LLRF mod­ules such as a phase con­trol loop sys­tem and an IF sig­nal pre-pro­cess­ing sys­tem have been in­te­grat­ed.
