                                                         Unique number of the signal group The signal groups are numbered consecutively. The preset number can be overwritten by a number which has not yet been assigned in the network.  |

                                                         Green time start  | 
                                                    
                                                         If you create a signal group for a signal group-based signal controller, enter the green time start in seconds here. If you create a signal group for a stage-based signal controller, this field is disabled. The green time start of the selected stage is used.  |

                                                         Green time end  | 
                                                    
                                                         If you create a signal group for a signal group-based signal controller, enter the green time end in seconds here. If you create a signal group for a stage-based signal controller, this field is disabled. The green time end of the selected stage is used.  |

                                                         Minimum green time  | 
                                                    
                                                         Enter the minimum green time in seconds. Note The value takes effect during green time optimization (Optimizing signal cycles and split of a single signal controller).  |

                                                         Amber  | 
                                                    
                                                         Enter the amber time in seconds.  | 
                                                
| 
                                                         Allred  | 
                                                    
                                                         Enter the Allred time in seconds. Note Time after the amber time of a signal group, in which no other signal group can have a green light.  | 
                                                
| 
                                                         Stages  | 
                                                    
                                                         If you create a signal group for a stage-based signal controller, you have to allocate one or several stages to the signal group. Note The signal group must be allocated to at least one stage.  | 
                                                
| Second green time start / second green time end | Using these attributes, you can define a second green time for the signal group. |
