I'm developing a machine with an ABB robot, and to save costs I want the robot a profinet master, with external operation buttons (start, reset), door locks, and TowerLamp connected to the robot via profinet. My question is how these external signals can be programmed logically in the robot system, which is easy to implement in a PLC, but how to implement it in the robot system? Can someone give me some advice? Thank you. (Currently my idea is to use MuiltiTasking + Interrupt, but I have a feeling that's not a good idea)
Does the ABB robot controller have softPLC functionality?

You can use MultiTasking, that works good if the tasks are not too complicated/extensive, you have to program some "binary state machines". I don't see why you will need interrupts for hat task.

Multitask works very well. Don't be afraid to use it. I wrote a program with 5 multitask. And also you can use cross connection together. Helps a lot

Thank you so much for your responses.

One thing is absolutely important for a parallel task: You have to program a short waittime in every task, otherwise the system will have erratic behaviour.
