Write the corresponding statement table program according to the following PLC ladder diagram.

Below is an example of how you might translate the given PLC ladder logic into a statement list (STL) program. This is a simplified version based on common PLC programming practices. Please note that the actual implementation may vary depending on the specific PLC model and programming environment used.

The STL format typically uses mnemonic instructions to represent logical operations, such as "LD" (Load), "AND", "OR", "OUT" (Output), etc. Here's a basic example:

LD I0.0
AND I0.1
OUT Q0.0
LD I0.2
OR I0.3
OUT Q0.1

This simple example shows two separate logic branches. The first branch checks if both I0.0 and I0.1 are true, then turns on Q0.0. The second branch checks if either I0.2 or I0.3 is true, then turns on Q0.1.

It’s important to ensure that your statement table matches the functionality of the original ladder diagram. If the diagram includes more complex elements like timers, counters, or function blocks, those would also need to be included in the STL code accordingly.
