———— SETTING VIRTUAL DIGITAL I/Os ————
5.1.6 Behavior
This object allows the assignment of Drive parameters to the “Virtual Digital
Inputs” so that the Master can write cyclically the values of these parameters.
The assignment of the Drive parameter is accomplished through the parameter
index; if the parameter for any reason cannot be assigned to a “Virtual Digital
Input”, an error code will be returned.
5.1.6.1 Write Virtual Digital Input configuration
In this example is shown the writing of the configuraton of the “Virtual Digital
Inputs”; the cases of positive and wrong writing are distinguished.
5.1.6.1.1 Write Single Virtual Digital Input Configuration
The data frame for the writing of the single configuration of the “Virtual Digital
Inputs” is composed as follows:
DATA TYPE FIELD VALUE MEANING
Byte Service Code 10hex
Set_Attribute_Single -
Common Service.
Class ID 6Ahex

See Note 1)
1) Byte or Word depending on the type of allocation executed by the Master.
2) The format of the Drive parameter index is Low Byte - High byte.
5.1.6.1.2 Write Single Virtual Digital Input configuration - Reply OK
If the single configuration of the “Virtual Digital Inputs” is written correctly,
the response is composed as follows:
