dear all ,

Greetings

please your help ,I have   three distributed water tanks the distance between every one and the supply pumps around 3 km so i try to make wireless communication between three slave logo_8 and the master one which near to pumps which will revive the water level signals from the three tanks ,I already made the program and the network between the four logos but during make  drag drop for network input NI and network output NQ the sequential serial of NI jump direct from NI11 to NI13,NI12 not inserted

and when i have try to make download to logo message came there blocks without  connection to output although i removed the program and wrote again

You must have a NI12 in your diagram, maybe outside of the visible area. Try to find it and delete the unused NI12.

In the past there were problems, if the NIx and NQx are not numbered in series. Try to use NI1, NI2, NI3 ... without intervals to avoid strange behavior.
