Features
Built-in Web Server
Each tET/tPET/PETL series module contains a built-in web server
that allows users to easily configure, monitor and control the
module from a remote location using a web browser.
Modbus Protocol
The Modbus TCP/UDP slave function on the Ethernet port can be used to provide data to remote
SCADA software.
All-in-one Module
A variety of I/O components are available on multiple channels in a single module, which provides the
most cost effective I/O usage and enhances the performance of I/O operations.
Automatic MDI/MDI-X Detection for Plug-and-Play
The RJ-45 port supports automatic sensing of MDI/MDI-x switching that can
automatically detect the type of connection being used by the Ethernet device
without requiring special straight or crossover cables.
Built-in Dual Watchdog
The Dual Watchdog consists of a CPU Watchdog (for hardware functions) and a
Host Watchdog (for software functions).
The
CPU Watchdog
will automatically reset it-self if the built-in firmware
encounters an abnormal situation.
If there is no communication between the module and the host (PC or PLC) for a specified period of
time (i.e., the Watchdog timeout), the
Host Watchdog
will set the digital output based on a
predefined safe-value.
