Slice I/O Terminal Introduction
Section 1-1
Parameter Backup and
Restore
Before replacing a Slice I/O Unit for maintenance, the parameter data set in
the I/O Unit can be backed up in the connected Communications Unit. The
backed up parameter data is compared with the replacement I/O Unit’s data
and the backed up data is restored to the replacement I/O Unit.
Online Replacement of I/O
Units
The Slice I/O Units are made up of 3 blocks (the base block, main block, and
terminal block) that can be separated from each other. This means you can
leave the base block connected to the Slice I/O Terminal with power supplied
to the Slice I/O Terminal and replace the main block or terminal block.
Note
Turn OFF the I/O power supply before replacing Slice I/O Unit
blocks. Also turn OFF any external power supplied to the terminals.
Automatic Baud Rate
Recognition
It isn’t necessary to set the baud rate on the GRT1-series Slice I/O Units.
Automatic Allocation of
Unit Numbers
Unit numbers are allocated automatically to the connected Slice I/O Units
from left to right and stored within the Communications Unit. It is not neces-
sary for the user to set these numbers.
Remote I/O
Communications
GRT1-series Slice I/O Units communicate with the host Master by remote I/O
communications through the Communications Unit. The Slice I/O Units’ data
is collected in the Communications Unit and exchanged with the Master in a
batch.
Unit Conduction Time
(Power ON Time) Monitor
This function records the total time that the Slice I/O Unit's internal circuit
power has been ON. A warning level can be set in the Unit and a warning flag
will be turned ON when the set warning time is exceeded. The Power ON
Time can be read with an explicit message command or from the Configura-
tor.
Unit Comments
A user-set name can be assigned to each Unit and recorded in the Unit.
Connected Device
Comments
User-set names can be assigned to each I/O device (sensor, valve, etc.) con-
nected to a Unit and recorded in the Unit.
Communications Error
History Monitor
The communications error log within the Unit can collect the four most recent
communications errors (communications error cause code and communica-
tions power supply voltage when error occurred). The information can be read
with an explicit message command or from the Configurator.
Last Maintenance Date
The date on which maintenance was performed can be written in the Unit.
The date can be written from the Configurator.
Digital I/O Unit Features
I/O Power Supply Monitor
This function detects whether the I/O power is being supplied and turns ON a
warning flag in the Unit if the I/O power supply is OFF. The flags can be read
with an explicit message command or from the Configurator.
Input Filter
The input filter function reads the input value several times during the set
interval and removes irregular data caused by noise and switch chattering.
This function can also be used to create ON/OFF delays.
Sensor Power ON Delay
When the I/O power has gone OFF, the sensor power ON delay function
blocks inputs for the first 100 ms after the I/O power is turned back ON. This
function prevents incorrect inputs caused by inrush current at startup after the
I/O power is turned ON.
