# DALI group control

In the case of DALI ballasts, control can be implemented in two ways. The first way assumes individual control of each ballast, while the second way assumes group control of selected ballasts.

 

**Individual control**:

1. From myGrenton application:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-44-17-5273-AM.png)

2. From input objects:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-44-48-0873-AM.png)

 

**Group control**:

1. From myGrenton application:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-46-11-2961-AM.png)  
where:  
**dali\_group16\_val** is a user feature:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-58-09-2492-AM.png)

**dali\_group16\_set** is a script with a **dali\_group16\_value** parameter:

```
CLU->dali_group16_val=dali_group16_valueCLU->DALI_MASTER_01->SetGroupDAPCValue(16,dali_group16_value,0)
```

![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-56-48-2755-AM.png)

2. From input objects:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-55-34-1467-AM.png)  
where:  
**dali\_group16\_switch** is a script responsible for changing the state of the group:

```
if(CLU->dali_group16_val>0) thenCLU->dali_group16_val=0CLU->dali_group16_set(CLU->dali_group16_val)elseCLU->dali_group16_val=254CLU->dali_group16_set(CLU->dali_group16_val)end
```

**dali\_group16\_change** is a script determining the direction of the hold action based on the value of the **dali\_group16\_direction** feature:

```
if(CLU->dali_group16_direction==0) thenCLU->dali_group16_direction=1elseif(CLU->dali_group16_direction==1) thenCLU->dali_group16_direction=0end
```

![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-51-20-1864-AM.png)

**dali\_group16\_direction** is a user feature determining the direction of the hold action:  
![](https://knowledgebase.grenton.com/hubfs/image-png-May-11-2023-06-49-46-5065-AM.png)

**dali\_group16\_hold** is a script responsible for increasing/decreasing the value of the group:

```
if(CLU->dali_group16_direction==0) then    if(CLU->dali_group16_val<250) then    CLU->dali_group16_val=CLU->dali_group16_val+5    CLU->dali_group16_set(CLU->dali_group16_val)    endelseif(CLU->dali_group16_direction==1) then    if(CLU->dali_group16_val>4) then    CLU->dali_group16_val=CLU->dali_group16_val-5    CLU->dali_group16_set(CLU->dali_group16_val)    endend
```
