I believe this uses a communication layer algorithm that locates an applicable Scaling parameter on the module.

There are three possible names:
/MYPARAM_SCALE
/PV_SCALE
/OUT_SCALE

The scaling parameter must be at the same level or path as the parameter it applies too. In a PID block there are two scaling parameters. PV_SCALE and OUT_SCALE. The PV parameter uses PV_SCALE and OUT uses OUT_SCALE

There is no SP_SCALE. No problem. The function will return the PV_SCALE for SP.

An AI Block has OUT_SCALE. So AI1/PV ends up using OUT_SCALE.

For a user defined parameter called VALUE, create a parameter called VALUE_SCALE at the same level in the modue.

If no scale parameter is found, I think 0-100% is used.
