Analog applications of S7-300

I am new to the S7-300 system, and the actual requirement is as follows: Output one channel from the SM332 2*12bit setup to one channel of the SM331 8*12bit setup. The value of the output channel is specified manually (0~1000.0). How to implement this in programming? (The input channel is configured for 4-wire 4~20mA, and the output channel is also configured for 4~20mA).
In the Stand library, within the TI-S7 Converting Blocks, FC105 is for AI, and FC106 is for AO.
How are the externally given values implemented? Or in other words, how to assign values to registers in a program (forced values, not forced digital signals)
And how can one obtain the current output value of a certain channel of the SM332? (Entering “Monitor/Modify” indicates that the output of peripheral devices cannot be monitored.) )

This is resolved; it can be implemented through the variable table!
