Hello Friends in this video we tried to cover api and instruction used in plc programming
CALL instruction
CJ instruction
FEND instruction
SRET instruction
Here's a brief explanation of these terms in a general context:
CALL (Call Subroutine):
This instruction is used to call a subroutine in the program. Subroutines are blocks of code that perform specific tasks and can be called from different parts of the program.
CJ (Conditional Jump):
Conditional jumps are used to alter the flow of the program based on certain conditions. If a specified condition is true, the program jumps to a designated location; otherwise, it continues with the next instruction.
FEND (End of Function):
The FEND instruction typically marks the end of a function or subroutine. It is used to define the boundary of the code that constitutes a specific function.
SRET (Subroutine Return):
This instruction is used to return from a subroutine or function to the calling part of the program. It transfers control back to the instruction immediately following the CALL instruction.
As for the API descriptions, Delta PLCs are programmed using specific software environments like Delta PLC WPLSoft or ISPSoft. The API calls and syntax may vary based on the programming language and software you are using. You should refer to the official documentation or user manuals provided by Delta Electronics for your specific PLC model and programming environment.
