A very practical tool from
Rockwell to assist in the design, simulation and load verification of an
industrial network is the Integrated Architecture Builder (IAB). A poorly
sized network will cause problems and consume time and resources for trouble-shooting
and maintenance. In this post we will show an example of using this
tool.
Download from the AB website, inserting
"Product Selection Configuration" in the Search box and selecting the
IAB during installation:
Create a new project within
the Integrated Architecture Workspace of type Ethernet-IP Capacity Subsystem, by
clicking Create> New Project:
Then select Ethernet-IP
Capacity sub-system
- Configure the project's hardware in the I
/ O blocks and click on Compute (Note: it is possible to add devices
within the 8 available blocks and to insert repeated devices, just
increase the Chassis count when editing the block).
- "Stress" the network with
different configurations:
- Requested Packet Interval (RPI) time
- Number of devices
- HMI on the network:
- Number of devices
- Number of Tags
- Frequency of consumption of Tags
For example, a project with a
PLC, Switches, Remote IO (normal and safety), VFDs and HMI:
In the example above, we see
that the usage is in red, that is, the system is under-dimensioned. In
addition, the program alerts you to the maximum number of devices of each
type. By changing some parameters, such as the IO RPI, it is possible to
significantly optimize the system. During design, a good practice is to
dimension the network so that it does not exceed the 50% limit, and
preferably be less than 20%.
