Chapter 5
Operation
This Chapter explains how to use the
EtherSeries gateway, once it is installed and
configured.
Operation
The gateway allows serial MODBUS RTUs to communicate and
interoperate with MODBUS/TCP based controllers. The
MODBUS standard protocol is an asynchronous protocol
designed to connect directly to computer asynchronous ports.
MODBUS has been extended to operate over Ethernet using the
IP protocol suite. This gateway converts between the
MODBUS TCP/IP protocol and MOBUS ASIII/RTU protocols
transparently.
Normal operation would consist of one or more Ethernet based
computers functioning as Modbus Master and one or more
MODBUS slave devices (usually RTUs) connected serially to
the gateway.
