24.4.5.10.1 Group Address Support for Virtual Target
For better utilization of the resources and register space, the Target mode supports the sharing of Group Addresses between the configured Virtual Targets.
The acceptance of Group Addresses by each Virtual Target ‘x’ through SETGRPA CCC is
determined by checking the following conditions:
- Whether the assigned Group Addresses to Virtual Target ‘x’ are less than four.
- Whether the total number of unique Group Addresses is less than four.
If either of these conditions is not met, the SETGRPA CCC sent to Virtual Target ‘x’ is NACK’d Common Command Codes (CCC).
