They are the I/O modules which deals with the field input (can be
temperature sensor, binary sensor, ...), process them and
communicate with the upper PLC/DCS through the communication
backplane (DeviceNet or others). I think they can use
either Linux and WinCE since the chip vendor supports both. I will
think both Linux and WinCE are good enough for them but the
engineer may be more familiar with WinCE.
