Hello, regarding to your inquiry we would like to inform you. I´m not sure what is exactly your problem but I hope I can help you with some examples which do you will find in the internet. In refer to your description you want to control example blower 2 and 3, or blower 1 and 5, or blower 2, 4 and 6. In STEP 7 there is a function of jump distributors. Here you can with the programming of the jump distributor to control the special blower in each jump. Please see the home page of the SIMATIC customer support: JL End; JU M00; JU M01; |

I attach a little sample code [:)] Function of the sample: M10.0 starts the sequencer and the sequence keeps on running until M10.0 is reset again. MW12 is the word for the start orders, for 10 blowers set this to w#16#07FE. The bit in the position to the right end (M13.0) must start as being "0". MW16 is for the selection of blowers. In the sample code it is set to w#16#0122 to start blower 1, 5 and 8. MW14is to keep track of where in the sequence we really are, since it is only bit M13.0 and M17.0 that are compared for the start order (due to the shifting instruction). M0.2 is the systempulse 100ms which shifts the word to the right and count up the counter. Replace this with whatever you want to trig the shifting. Looking at the code now, I see that there is really no need for two words to use in the shifting since MW12's bits are all set to "1" for all the blowers. But sometimes the mind works slower than the fingers...[:)] AttachmentFC10.zip (779 Downloads) |
