General Information
The ETC II Network Communicator is a multi-port Internet-to-serial that
connects multiple serial RS-485/422 or wireless ZigBee devices to the
Internet via a local Ethernet network or via public telephone lines. It can also
be used as an Internet-to-Internet router for connecting master stations to
remote slave devices that are directly connected to the Internet. The ETC II
provides transparent master-slave connections using TCP/IP versions of the
popular industrial fieldbus protocols such as Modbus RTU, DNP3, and
SATEC ASCII.
The embedded Data server allows the ETC II to automatically acquire data
from slave devices and to store it in the memory exchanges or in the data log
files in non-volatile memory, so a user application can read blocks of
acquired data directly from the ETC II exchanges without waiting for a
response from slow serial and wireless devices. The application can also
write data to slave devices via the ETC II exchanges instead of waiting until a
remote device is accessible. The Data server may be programmed to
monitor the slave device’s status registers for specific events and to record
them to a log file, and send alerts to a remote server.
