Operating the TP 070

Operating Screens  
What is a screen?  
Screens visualize the progress of processes and display specified process values.  
A screen contains logically related process data which the operating unit can both  
display and modify by operating the individual values.  
Screen partitions  
A screen is basically composed of static and dynamic sections. The terms “static”  
and “dynamic” do not refer to the possibility of dynamically positioning screen  
partitions but to the connection to the PLC.  
Static partitions, e.g. text and graphics, are not updated by the PLC. Dynamic  
partitions, e.g. input and output fields and bars, can be linked to the PLC and  
display current values constantly read in from the PLC memory. Their connection  
to the PLC is established by means of tags.
