Modbus gateways can be used to integrate Modbus networks in a wide variety of settings.
But as each setting has its own requirements, users may not understand how a gateway
helps, or if it’s appropriate for their specific needs.
The following scenarios are examples only, and many others are possible. Contact B&B
Electronics technical support for information on other applications.

The MESR Modbus gateway module connects serial slaves, so Ethernet SCADA masters
can control these. As slave IDs must be unique in a single system, these must be changed
