Issue No: 11
7. APPLICATION
Remote data acquisition
Process monitoring
Industrial process control
Supervisory control
Security systems
Laboratory automation
Building automation
Product Test/Simulation in Production
The MINT I/O can also be used by end users, package vendors as well as
system integrators who want to upgrade their existing systems or optimize
their automation offerings.
Redundant communication application where two master connections to a
single device, creating redundancy in serial connectivity instantly increases
reliability, uptime and accessibility for critical Industrial applications.
7.1 Application Configurations:
There are a number of different configurations in which the IO modules may
be used in a System. Some are listed as follows:
7.1.1 I/O Expansion:
There are a number of devices such as
PLC
’s (Programmable Logic
Controllers) and
HMI
(Human machine interface) which have a MODBUS
Communications facility available. Many PLC and HMI manufacturers provide
Modbus Master and Modbus slave drivers to communicate directly with third
party devices using Modbus protocol using different kind of hardware
connection. PLC/HMI can be configured as a MODBUS Master. IO modules
are attached to the RS485 network and configured as RTU slaves. The
address setting is via dip switches on the IO module itself. The PLC/HMI
system use mINT IO modules as remote I/O reducing cabling costs and
increasing the I/O capability of the control system.
