2 Overview
Under the catchword "Industry 4.0", more and more new communication and information
technologies are finding their way into industrial automation. In order to be able to
implement these requirements efficiently and as quickly as possible, attempts must be
made to reduce the high level of complexity through modularisation and standardisation.
In this context, OPC UA has proven to be a forward-looking communication standard.
This is because OPC UA fulfils the Industry 4.0 requirement for independence from
manufacturer, industry and operating system communication.
Since OPC UA not only transmits machine data, i.e. process values and measured
values, but can also describe them semantically, OPC UA is becoming increasingly
important when it comes to transferring machine data from controllers to higher-level
systems.
One solution for reading process data from Mitsubishi Electric controllers and robots that
do not have an OPC interface as standard is the RD55UP12-V module with installed IBH
Link UA software, called IoT Gateway .
This solution is a server/client module. The OPC client function also enables OPC servers
to exchange data with each other. For example, controllers or other devices with OPC UA
from different manufacturers can exchange data via this function.
Communication with the controller is via TCP/IP.
The IoT Gateway has an Ethernet port for the machine level and an Ethernet port for the
control level.
Only OPC accesses are possible on the control level. A firewall is integrated between the
two levels. The ports are configured via the GX-Works3 programming software of the iQ-R
CPU.
2.1 System structure
As a minimum configuration, the IoT Gateway always requires a base rack, an iQ-R CPU
and the RD55UP12-V module. To establish a connection to several controllers, a switch is
required at the process level.
