Experimenting with chatbot ChatGPT for programming a digital twin of a production

Can ChatGPT ( https://chat.openai.com/chat ) write Tecnomatix Plant Simulation #PlantSimulation SimTalk code? – Not yet but it looks like it is only a question of time and training.

The result is truly amazing!?

Question to ChatGPT:

Please write an exit control in SimTalk code for Tecnomatix Plant Simulation to move a movable unit to station2

This is the answer by the ChatGPT bot, (including a nice answer, what it means!):

This code uses the "on exit" control in SimTalk, the programming language used in Tecnomatix Plant Simulation, to trigger a movement of a movable unit from Station1 to Station2. When the movable unit exits Station1, the code first checks if Station2 is free using the "isFree" function. If it is, the code then checks if the movable unit is available using the "isAvailable" function. If both conditions are met, the code moves the unit to Station2. If Station2 is not free or the movable unit is not available, the code will display a message indicating the reason for not moving the unit.

Note: This is a more complete example, however it is important to define the movableUnit, Station1, and Station2 in your simulation model and also check if the movable unit is in the correct location before moving it.

So yes, the answer is (still?) wrong but the structure is clear, detailed and for me very promising.

And what else can AI do for you?

If you don’t understand code, someone else wrote, or if you like a detailed documentation: Ask your friendly chatbot to add some lines of explanations:

e.g.:

GPT please try to add comments on the following code:

waituntil not self.~.Empty and self.~.IsReady

for var x := 1 to self.~.XDim

???????????????var mu := self.Location[x,1].Cont

???????????????if mu /= void

??????????????????????????????self.~.IsReady := false

??????????????????????????????var targetAngle := 180 - (x-1) * 360/self.~.XDim

??????????????????????????????wait self.~._3D.playRotation(self.~.currentAngle, targetAngle, 10)

??????????????????????????????self.~.currentAngle := targetAngle

??????????????????????????????wait 2

??????????????????????????????mu.move

??????????????????????????????waituntil mu.~ /= self.~ -- Wait until part has left

??????????????????????????????self.~.IsReady := true

??????????????????????????????return

???????????????end

next

And this is the AI answer:

Or if this is too long and too detailed:

GPT please briefly summarize the meaning of the SimTalk control:

waituntil not self.~.Empty and self.~.IsReady

for var x := 1 to self.~.XDim

var mu := self.Location[x,1].Cont

if mu /= void

self.~.IsReady := false

var targetAngle := 180 - (x-1) * 360/self.~.XDim

wait self.~._3D.playRotation(self.~.currentAngle, targetAngle, 10)

self.~.currentAngle := targetAngle

wait 2

mu.move

waituntil mu.~ /= self.~ -- Wait until part has left

self.~.IsReady := true

return

end

next

Is summarized by the OpenAI ChatGPT:

This SimTalk control is a script that rotates a 3D object by a certain angle and then waits for a specific event to occur before continuing. The script waits until the object is not empty and is ready, then iterates through a range of values (x) from 1 to the object's X dimension. Within the loop, the script assigns a variable (mu) to the contents of the object's location at the current x and y value. If the contents are not void, the script sets the object's IsReady status to false, calculates a target angle based on the current x value, rotates the object to the target angle, waits 2 seconds, moves the contents (mu), and then waits until the contents are no longer in the object. The script then sets the object's IsReady status to true and exits the loop.

Nice isn't it?
