Using ChatGPT to write ladder logic

[DonNH 3]

Anyone successfully used ChatGPT to write ladder code?

I've tried a few times with zero success. At least part of the problem is just trying to interpret the "ladder" that it creates using a very limited set of ASCII characters.

 

For example, I asked this question:

      Can you generate ladder logic to try to correct an error condition:

1) Error condition 'error 1' occurs
2) system runs subroutine 'sub1'
3) check is made to see if error condition is still present
4) If error condition is still present, system outputs 'Stop'
5) if error condition is cleared, system outputs 'cleared'

 

and got this result:

 

+-----------------+
| Start           |
|                 |
|  +---[ Error 1 ]---+
|  |              |
|  |              V
|  |         +--------------+
|  +------[ Run Sub1 ]-----+
|            |            |
|            V            |
|  +----[ Check Error 1 ]---+
|  |            |            |
|  |            V            |
|  |    +-----[ Output Stop ]---+
|  |    |       |            |
|  |    |       V            |
|  |    +---[ Error Cleared ]--+
|  |            |
|  +------------+
|
|  +---[ Output Cleared ]--+
|  |                       |
|  V                       |
+-------------------------+
 

with this explanation:

 

Explanation:

1. The ladder logic starts with the "Start" condition.
2. If "Error 1" occurs, the system runs the subroutine "Run Sub1."
3. After the subroutine, it checks if "Error 1" is still present.
4. If "Error 1" is still present, it outputs "Stop."
5. If "Error 1" is cleared, it outputs "Cleared."
6. The ladder logic then loops back to the "Start" condition.
