This read-only object is available for diagnostic feedback purposes. It reflects the measured over/under
voltage powering the controller as well as the internal microcontroller temperature. FD1 is over temperature
fault detection, FD2 power over voltage fault detection and FD3 power under voltage detection. The physical
unit for this object is volts and ºC, respectively.

2.4.83. Object 5041h: FD Set Threshold
This object sets the value that will flag a fault detection error in the 2IN-2OUT-SIG-CO if the measured field
value (5040h) goes above (FD 1 and FD 2) or below (FD 3) this limit. If error checking on the fault is enabled
by object 5050h, then the module will flag an appropriate error on that channel. This value must be in the
same units as the field value for the fault, as determined by the sub-index.
