Interrupt Module
Branching to subroutines
The interrupt module QI60 is suitable for appli
-
cations demanding quick responses.
앬
Every input in this module is assigned to a
pointer which serves as a breakpoint for a
subroutine
앬
If an interrupt/alarm signal is applied at an
input, the PLC program is interrupted after it
has worked through the current statement
and a subroutine assigned to the input is first
processed
앬
Galvanic isolation between process and con
-
troller by means of a photocoupler is a stan
-
dard feature
앬
Only one QI60 can be installed per
PLC system

Interface Module
Data exchange with peripheral
devices
This module enables communication with
peripheral devices via a standard RS232 interface.
The peripherals are connec ted point-to-point
on a 1:1 basis.
앬
The QJ71C24 provides one RS232 and one
RS422/485 interface and the QJ71C24-R2 pro-
vides two RS232 interfaces
앬
Enables PCs connected to the system to
access the full data set of the MELSEC Q CPU
using graphic process supervision or monitor-
ing software
앬
Support for plain ASCII data exchange with
connected devices such as barcode readers,
scales and identification systems
앬
Options for connection of a printer
앬
Integrated flash ROM memory for logging
quality, productivity or alarm data that can be
printed out when required
