Hi,
I'm new to PLC ladder diagrams and I'm stuck in a problem where I'm given a ladder diagram (please refer to the attached file "Problem"). I need to have a PLC 5/30 control System. There are 8-point I/O cards with one-slot addressing.
It is required to draw the inputs and outputs which are attached with the post as "Inputs" and "Outputs" respectively. As per my understanding there are 4 inputs (stop-1, start-1, stop-2, start-2) and 5 outputs as shown in the attached file.
I tried to construct the PLC ladder diagram (please refer to the attached file "PLC_Ladder_Diagram").
In this diagram I could not include the float switch which energizes CR2. Also I did not understand how to include OL's in the PLC ladder diagram.
I tried to run a simulation of the PLC Ladder diagram though it is incomplete because I did not how to include the float switch. Attached file ("Problem1.plc"). Please help me to include the float switch in the PLC Ladder diagram.
Thanks in advance.
Appreciate your help.
