It should be useful, for example, in the PID tuning phase. At this way, when Reset = true, the ramp function is deactivated.

Step 7: Your Ethernet address will auto-populate in the License Server or Node-lock hostid field. In the attached example, the same variable was used in the Input and SubstituteOutput inputs. 1 License server -> RLM server Info’, but it is also possible to access it over the network. Rating: (0) Hi, I am migrating a step 7 v5.6 program to TIA portal v15.1 and I have some problems with a list function that worked previously in step 7. The substitute value input, together with the reset button, could be used to “turn off” the rum function. These gradients could be found in the block instance DB, with the names: Qualified personnel are those who, based on their training and experience, are capable of identifying risks and avoiding potential hazards when working with these products/systems. The gradients express how many “unitis” will increase / decrease per second. task in accordance with the relevant documentation, in particular its warning notices and safety instructions. With this block, it is possible, for example, to generate a ramp for PID set points and so, to get soft and controlled changes of the process variable even with step changes in the original set points. 
The RampFunction block enable to limiting the rate of change and the limit values of a signal with different gradients for positive/ negative/rising/falling signals As from STEP 7 V15 it available a new instruction for ramp generation: RampFunction (Intructions > Technology > PID Control > Auxiliary Functions)
