What do these three DCS signals represent?

What are the three digital inputs represented by DI×3? Do they refer to on, off, and fault? Experts, please
Operation status: 1DI fault, 1DI manual/automatic switch, 1DI current 4~20mA, start/stop, 2DO
The expert is online to answer questions; thank you very much
Transport status: 1, Automatic/Manual: 1, Faulty: 1
Is it correct to understand variable frequency feedback as an input of 4-20mA and variable frequency starting as an output of 4-20mA?
Open to full position, close to full position, fault signal； Moreover, this IO table is highly irregular; what is a 4–20 mA current signal? Valve opening degree? Let’s make a decision after confirming first.
The three DI values represent the belt operation status, manual/automatic mode, and fault condition, respectively. One AI has a current of 4–20mA, and the two DOs are for start and stop. There are six signals in total
Yes, the feedback is a 4~20mA input, while the setpoint is a 4~20mA output
Operation status: 1DI fault, 1DI manual/automatic switch, 1DI current 4~20mA, start/stop, 2DO
