Selection (Value)
Default: Read Only
Range: 0000h - FFFFh
Displays the status of digital inputs DIIL and DI6 - DI1. This word is
updated only after activation/deactivation delays (if any are specified).
Bits 0 - 5 reflect the delayed status of DI1 - DI6; bit 15 reflects the
delayed status of the DIIL input.
This parameter is read-only.
Default: Read Only
Range: 0000h - FFFFh
The electrical statuses of the digital inputs can be overridden for eg.
testing purposes. A bit in parameter 10.04 DI force data is provided for
each digital input, and its value is applied whenever the corresponding
bit in this parameter is 1.

Default: Read Only
Range: 0000h - FFFFh
Contains the values that the digital inputs are forced to when selected
by 10.03 DI force selection.
Bit 0 is the forced value for DI1; bit 15 is the forced value for the DIIL
input.
Default: 0.0 s
Range: 0.0 to 3000.0 s
Defines the activation delay for digital input DI1.

*Electrical status of digital input. Indicated by 10.01 DI status
**Indicated by 10.02 DI delayed status.
Default: 0.0 s
Range: 0.0 to 3000.0 s
Defines the deactivation delay for digital input DI1. See parameter
10.05 DI1 ON delay.
