Object 3474h: Parameters for digital inputs

This set of objects is used to set extended parameters for some digital input functions. The parameters can be used for different DINx.MODEs. Therefore the scaling might be different or no scaling is used at all.

Two subindices build an access object to one of these parameters, because they are 64-bit numbers internally, e.g. object 3474 sub 1 gives access to the low 32 bits of DIN1.PARAM whereas 3474 sub 8 sub 4 gives access to the high 32 bits.

If access to the whole 64 bit number is needed the higher bits must be written first. The access to the lower 32 bits then writes the parameter. If the to be written value fits into 32 bit, only the lower part needs to be written. The most-significant bit is then taken as sign-bit for the number.
