Introduction
There are many reasons a Modbus gateway might be used to integrate Modbus networks. However,
every situation has its own requirements and difficulties. Users may wonder how the gateway can
help or even if the gateway is suitable for the system.
This chapter presents some case studies to help guide. If you can not find the case the same as yours,
it does not mean the MGate MB3000 is not suitable with you. Please contact Moxa and we will work
it out with you.
Replace Serial Masters with Ethernet Master(s), Slave IDs
are Configurable
In this scenario, the original control system consists of several serial-based systems. In each system,
a serial master directly controls serial slave devices, as follows:
The MGate MB3000 can connect to each serial slave so Ethernet SCADA masters will be able to
control them. However, since slave IDs cannot be repeated in a system, we will need to change the
IDs of some of the slaves in order to integrate them into a single network, as follows:
