Pdu Transmission

Basic Networking Concepts - UVic.ca

Data Transmission-In modern networks, data are transferred using packet switching.-Messages are broken into units called packets, and sent from one ... -The data exchanged, known as Protocol Data Unit (PDU), goes back and forth through the layers, each layer adds or removes its own header and vice-versa.

MODBUS MESSAGING ON TCP/IP IMPLEMENTATION GUIDE V1

the MODBUS PDU has a fixed length, the function code alone is sufficient. For function codes carrying a variable amount of data in the request or response, the data field includes a byte count. When MODBUS is carried over TCP, additional length information is carried in the MBAP header to allow the recipient to recognize message
