To some extend, space electronics have a lot in common with stuff used to manage industrial plants.

For examples in Chinese megascale steel mills, while SCADA's are used for monitoring and higher level control, operational aspects are handled by handcrafted PLCs made of modern analogues of 7400 series, 8t sram, redundant sensors, quoruming and BCH coding, mram, mems oscilators, and all solid DC-DC conversion, and all of that is provided with manual overrides

Most important feature of all of this is that it provides hard, near physical, impediment to wrong inputs from higher level control systems (SCADAs.)
