Vlrtual Digital Output; Virtual Digital Output Descriptors - GE Profibus - DP Bus Instructions Manual

8.2. VIRTUAL DIGITAL OUTPUT
As to the virtual digital output the parameters involved are:
- Parameter index 5EFDh: virtual digital output configuration.
- Parameter index 5EFFh: reading of virtual digital output values.
Parameter 5EFDh: 16-element array Unsigned Int.
This array is used to configure the virtual digital output and shall therefore be written before using these outputs.
It contains the drive parameter index assigned to the output. These ouputs are then controlled through the
5EFFh parameter- type Unsigned Int - where the single Bit status corresponds to the status of the virtual digital
output assigned through the configuration array.
Example:
The 0 element of the 5EFDh parameter array coctains the 215Ah parameter index referred to the DV-300
drive, which means
Ramp+.
The operation is the following: after configuring the 0 element of the 5EFDh parameter with the 215Ah
parameter index, the
Ramp+
status of the DV-300 drive is read through the Bit 0 of the 5EFFh parameter.
8.2.1. Virtual digital output descriptors '
The 5EFDh parameter is used for the virtual digital ou(put configuration and can be written/read by single element.
