Hey there folkz. I have a test station here that i prep for 2021. Im not to well used for plc progamming so i hope i can get my answers here. The task is to make A program to be created in sequence with a percentage increase in air pressure in the tank, with fixed consumption. The working area of the tank is 0-5bar The sequence is as follows: Tank pressure increases to 25% The pressure is kept stable for 1 min Tank increases to 50% held for 1 min Tank increases to 75% held for 1 min Tank drops to 25% and the sequence is reatarted. i understand that pid is involved in one ladder by it self, so my question is how do i implement the values into a sequance cheers
NickV posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareDear, Since a few weeks I started working with the Vision PLC 430 J T 2. I have three expansion modules (2 for analog inputs and 1 for load cells). Recently I've started writing down the logic of my final program. Until now I only have experience with the Siemens S7 with associated software. I want to create a sequence where the transition from state to state is based upon conditions. Only one transition can be true at any point and the sequence is always the same. I've always done this with flip flops which set and reset each other. Now I’m searching for the correct way to implement this into the Vision software. Can someone advise me on this? Thank you in advance! Nick Verlooy
