please help me, how to make this circuit?
If timestamp2 is activated less than 30s aftertime stamp1, then output1; otherwise output 2.
To compare 2 values from different inputs - you need either a context to collect data or join them to one message object. Here is the second option to use one msg object:
The payload contains the timestamps of both Inject Nodes - as timestamp1 and timestamp2

The switch creates the difference and send the msg if between 0 and 30,000 ms to output 1 otherwise to output 2

Thanks. It seems to be what I need.
I also need to add a condition - if the timestamp1 is not activated at all, but the timestamp2 is activated, then the output2.
Just change the join node to wait for 1 instead of 2 messages.
If there is still an old timestamp1 stamp is in the join object it doesn't matter as then the time difference is greater than 30 s as well and the otherwise case will be chosen.
Yes, but then activating timestamp1 also results in output2. I need to process only the timestamp2. Add a filter?
Hmm - yes - but I thought that was the intention. If timestamp2 is activate and then timestamp1 and you want to have this as output 1 then you need the absolute value - then it doesn#t matter which one is first - and sends always to output 1 - if the difference is < 30s.
No, not like this. Timestamp1 is only a condition for timestamp2. There should be no action after it.
This will work as it should. But after each deployment, the first hit will be incorrect.
Ok - so you there is a strict order.
- If timestamp1 is first and then timestamp2 is within 30s then output1
- If timestamp1 is first and then timestamp2 is after 30s then output2
- If timestamp2 is alone then output2
- The next timestamp1 has to be ignored and the next timestamp2 directs to output 1 or 2 dependent on time difference.
I fear you need a function node.
I try to implement this.
Would adding a msg.complete to timestamp2 do what you need.
e.g.

Yes. Looks like this is exactly what I need.
