  • Page 9: Introduction To Modbus

    1–4 Introduction Introduction to MODBUS MODBUS RTU (Remote Terminal Unit) Protocol is a messaging structure used to establish master–slave communications between intelligent devices. When a MODBUS master sends a message to a MODBUS slave, the message contains the address of the slave, the function, the data and a check sum. The slave’s response message contains fields confirming the master’s request, any data requested and an error–checking field.

  • Page 10: Terminator I/O System

    1–5 Introduction Terminator I/O System Terminator I/O is a modular system which combines the functions of terminal blocks and I/O modules for distributed I/O. Each Terminator I/O system has the following components: a Power Supply, a Base Controller, and one or more I/O Modules and I/O bases.

  • Page 11: T1K-Modbus Base Controller

    1–6 Introduction T1K–MODBUS Base Controller The T1K–MODBUS Base Controller is a slave module that functions as a controller for Terminator I/O on a MODBUS network. Note: It is recommended to use the T1K–MODBUS Base Controller in a “scan based” (polled) control system rather than in an “event–driven” control system. As a slave, the Base Controller does not have the ability to report an error condition to the MODBUS network master.
