Unlike T100MD+ PLC which outputs a +5V on pin 13-15 and 0V on pin 9-11, the T100MX3224R require an external +5V DC analog voltage reference to by applied to the AVcc and AGND inputs.  i.e. You have to find a good stable analog power source +5V to be applied to the analog reference terminal. Take note that connecting a wrong voltage to the AVCC and AGND will instantly kill the CPU so be careful.
