Object 3477h: Parameters for virtual digital inputs

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

Two subindices build an access object to one of these parameters since they are 64-bit numbers internally.

For example:

  • Object 3477 sub 1 gives access to the low 32 bits of VDIN1.PARAM

  • Object 3474 sub 9 gives access to the high 32 bits of VDIN1.PARAM

If access to the whole 64 bit number is needed then 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 bits, only the lower part needs to be written. The most-significant bit is then taken as sign-bit for the number.
