Abstract
MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model. MODBUS provides client/server communication between devices connected on different types of buses or networks. MODBUS is a confirmed service protocol and offers many services specified by function codes. MODBUS function codes are elements of MODBUS Request/Reply PDUs. The objective of this document is to describe the function codes used within the framework of MODBUS/TCP transactions.
