![]() ![]() But again there is an %I2.6 that has been wiped out by Network 4's usage of %ID2. ![]() This makes me think you have other memory overlap occurrences.ģ) Network ? makes me wonder if you are using special system bits which are by default covering %M0.0 to %M1.7. I am not liking the fact that you are using %ID2 (input double word 2) to read the elapsed time. I am wondering what the value is for PT in the TON. The next coil overrides the previous coil's result.Ģ) Network 14 is not clear what the issue is. The code segments you shared leaves me with little answers.ġ) Network 4 has several coils for the same memory bit. Please bear in mind I may have missed something simple! Is there anything simple I am missing for this to be happening? Problem 3: there are several timers to stop the machine cycle if the timers run out, the ´stop cycle´ shows as being active in the timer Network, but in the Network where it stops the machine via a SR bit, doesn´t show as active and doesn´t stop the machine. If I change it to a N/O input then it works fine. Problem 2: An output Q1.0 starts a timer to monitor a particular function, when this is set to Positive Edge it show it as being active, but the timer after it doesn´t start. Problem 1: I have a series of TON / TOF timers to sounds a startup sound when the machine starts, these go to Q0.0, in TIA with monitoring it shows Q0.0 as being on, but on ther PLC it isn´t. I have checked memory assignments and there were quite a few overlapping, so they have been corrected. I am getting quite a few unexpected things not happening as expected. I have some strange problems with my S7-1200 program in TIA.
