Overview

The controller I/O has the following types of I/O:

Standard I/O

This digital I/O comes standard with the controller.

Expansion I/O

This is optional digital I/O that can be added to the controller to expand standard I/O. The boards with 24 inputs and 16 outputs can be added. (The boards cannot be added to the T and VT series manipulators and some of the RC800 series.)

Fieldbus master I/O

An optional board for the controller to expand the standard I/O. You can add one of the following boards which support the fieldbus master board. (PC)

DeviceNet, EtherNet/IP, PROFIBUS-DP

Fieldbus slave I/O

The Fieldbus slave includes the standard functions (Modbus RTU and Modbus TCP), and the options. As an option to add to the controller, you can add one board (controller: RC700 series, RC90 series) or module (manipulator: T, VT, Controller: RC800 series) corresponding to the following fieldbus slaves:

DeviceNet, EtherNet/IP, PROFIBUS-DP, CC-Link, PROFINET, EtherCAT

Hand I/O

Standard digital I/O for T series.

Memory I/O

This is built-in memory bits that can be used for inter-task communications.

Analog I/O

This is option to add analog input/output function to the controller. (The boards cannot be added to the T and VT series manipulators and some of the RC800 series.)

For Standard, Expansion, Fieldbus master, and Fieldbus slave I/O, there are input bits numbered starting with 0, and output bits numbered starting with 0.

For memory I/O, each memory bit is both an input and an output.
