HELLO guys

I have 8 hopper , for that 8 hopper I have 8 selection input each for indivisual  hopper

I need to select hopper according to input which give to plc.

if more then one input for selection for hopper then hopper out will be according to priority I have given

for example I given priority to j1 .if ji selection input is there if j1 and j2 and j3 input selection is given then hopper out will be  according to priority I have given

suppose I have given j1 first then j2 then j3 then j4 whether all selection input on...please guys help me to do it in structured text in omron

First, why does it need to be in structured text?

Second, have you written up a list of the possible scenarios so you can begin programming?  First step in writing a PLC program is to build a complete sequence of operation.

I guess in st it easy and less time consuming 

While in ladder a very big progam i have to written

There would be more than one solution to your programming requirement.

The attached program printout is in ladder, but functions similar to your description.

This program works as a simple first in, first out with no priority to a specific hopper.

I don't program in structured text, so this is all I would have to offer.

I hope this is helpful.
