Communication Security
An account and password are required when logging into the
OME-ET-7000/OME-PET-7000 web server. An IP Address filter is also
included, which can be used to either allow or deny connections from specific
IP addresses.
Modbus/TCP, Modbus/UDP Protocol
The Modbus/TCP, and Modbus/UDP slave functions on the Ethernet Port can
be used to provide data to remote HMI/SCADA software based on the
Modbus/TCP driver.
Built-in Multi-function I/O
A variety of I/O components are combined with multiple channels in a single
module, which provides the most cost effective I/O usage and enhances the
performance of the I/O operations.
Automatic MDI/MDI-X Crossover for Plug-and-Play
The RJ-45 Port supports automatic MDI/MDI-x, meaning that it can
automatically detect the type of connection to the Ethernet device without
requiring dedicated straight or crossover cables.
Built-in Dual Watchdog
The Dual Watchdog consists of a Module Watchdog and a Host Watchdog.
The activities of the outputs are also associated with the Dual Watchdog.
The Module Watchdog is a built-in hardware circuit that monitors the
operating status of the module and will reset the module if a failure occurs in
either the hardware or the software.
The Host Watchdog is a software function that monitors the operating status
of the host, and is used to prevent network communication problems or host
failures. When a host watchdog timeout occurs, the module will reset all
outputs to a safe state in order to prevent any erroneous operations of the
controlled target.
