Slice I/O Terminal Introduction Section 1-1
1-1 Slice I/O Terminal Introduction
A Slice I/O Terminal is a building-block style remote I/O terminal made up of a
Communications Unit and a number of Slice I/O Units, which each provide a
small number of I/O points. The Slice I/O Units communicate with the host by
remote I/O communications (cyclic communications) through the Communica-
tions Unit. Remote I/O communications (cyclic communications) can be
started just by setting the Communications Unit’s node address and turning
ON the power supply.
Since the Slice I/O Units expand the system in small I/O increments, a flexible
system can be assembled to exactly match various customer applications,
with less labor and space.
1-1-1 Features of the GRT1-series Slice I/O Units
The GRT1-series Slice I/O Units have the following features.
Features Shared by all Units
Small I/O Increments The GRT1-series Slice I/O Units have just a few I/O points (2 to 4 points) per
Unit, so the application can be flexibly constructed to match the space and
capacity requirements.
Building-block Style
Terminals
Slice I/O Terminals are building-block style Units that can be expanded by
attaching additional Slice I/O Units to the side of the Terminal. Up to 64 Slice
I/O Units can be connected to one Communications Unit.
Time-saving Screwless
Terminal Blocks
Slice I/O Units are equipped with screwless clamp terminal blocks, which can
be wired just by inserting the wire into the terminals. Wires can be removed
just by pressing the release button and pulling out the wire.
