The EMB-02 is designed for mounting on a standard DIN rail, or
for direct mounting on a wall. For easy connection to your
LAN, the gateway supports 10BaseT or 100BaseT with auto-
sensing.
EtherSeries EMB-02 Functions
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 ASCII/RTU protocols
transparently.
The EMB-02 enables one or more MODBUS controllers to
communicate with modes ASCII/RTU based serial RTUs. It will
not allow MODBUS/TCP RTUs to operate with a serial
MODBUS controller.
Other Features
Dual Serial Ports
The EMB-02 contains two serial ports. The two serial
ports are independent, and may be used with different
hosts and different serial protocols (RTU/ASCII) as well as
different MODBUS address ranges and timeouts.
Multiple Hosts
The EMB-02 may communicate with multiple host controllers.
