Hi, in my current project I have a button on my touchscreen. If this button is pressed, MB33 is set and afterwards MB 10 should be set too. But, as you can see in the image below, the execution of the net stops before MB10. Basicly I copied this structure out of this tutorial : https://www.youtube.com/watch?v=8RyFPPE3Hdk&feature=youtu.be&t=572 In the tutorial they use the same sequence of contact and coil to turn a "LED" on the touchscreen on and off. Any ideas, why it doesnt work for me?
Hello, I am a first time user for the program and so far i've been learning from using the tutorials and i'm struggling to configure a relay output connected to a solenoid. So from what i've found i believe i have assigned the solenoid to O0 and have added this to my ladder. Can anyone confirm if this is correct? essentially i need the solenoid to open when a button is pressed for 2 seconds. Thanks in advance
Hi, A subroutine in my program uses a few timers. However, when the first timer starts it then stops after only 0.15 seconds have elapsed - the preset value is 10s - and the program flow does not progress beyond that ladder net. Attached is a screenshot showing the relevant part of the ladder during runtime. Sorry if the solution to resolving this is really obvious, but please could someone suggest how to correct this? Many thanks in advance. - James
