i hope someone can help me with this problem:
If a collision body on a transport surface passes the collision sensor, the sensor is triggered once. If there is a jam on the transport surface the collision sensor is triggered permanently.
I want an operation (emergency stop or jam breaker) in the sequence editor to start if the collision sensor is triggered longer then, for example, 4 seconds. How can i do that?
Solved! Go to Solution.
there are several ways to do it in MCD.
One of the easiest way is to use a "Expression Block".
In this "Expression Block" dialog you can define a simple time counter that will count up when the sensor is triggered and set to zero if the sensor is not triggered.
Here is also a Video and a NX Part file as reference:
You could even define it as a reuseable XML Template if you want.
thats exactly what i was looking for. Thank you very much.
But the use of the "Expression Block" leads me to another question. There are so many possibilities to implement features. When do I need (or should use) an "Expression Block" or an "Runtime Expression" or the "Signal Adapter"?
At the moment i use the "Signal Adapter" to combine different signals and i use the combined signal as a condition object in the sequence editor. But i am not sure if thats the way it was meant to be.
