Hi
I'm making C codes for modbus protocol. but I cant find the template for framing Poll Controller (function code:14).
does anyone know it's template for master request and slave's response?
 

Although fc 14 is mentioned in the openmbus specification, I don't see it any recent MODBUS document. I wonder if it's a deleted legacy function code.
