Modbus protocol
The Modbus/TCP slave function is for providing data to remote SCADA software
on the Ethernet network.
Built-in Multi-function I/O
All Digital Output modules provide:
Power on value (On boot up, the DO status is set to the Power-on value)
Safe value (If Modbus/TCP communication is lost for a specified period, the DO
status is set to the safe value)
All Analog Input modules provide:
High/Low Alarm
High/Low Latch value
All-in-one module
The various I/O components are mixed with multiple channels in a single module,
which provides the most cost effective I/O usage and enhances performance of the
I/O operations.
2-way isolated noise/surge protection
To protect the hardware from damage caused by noise and surge, the ET-7000
module is designed with isolation circuits for Ethernet, and I/O.
Built-in Dual Watchdog
The Dual Watchdog consists of the/a Module Watchdog and the/a Host Watchdog.
The Module Watchdog is a built-in hardware circuit that can be used to monitor
the operation of the module and will reset the CPU module if a failure occurs in
either the hardware or the software.
The Host Watchdog is a software function that can be used to monitor the
operating status of the host, and is used to prevent network communication
problems or host failures.
Automatic MDI / MDI-X crossover for plug-and-play
The RJ-45 port support automatic MDI/MDI-x that can automatically detect the type of
connection to the Ethernet device without requiring special straight or crossover
cables.
Ventilated housing designed to operate between -25 ~ +75°C
The ET-7000 is housed in a plastic-based shell/case with a column-like ventilator that
helps to cool the working environment inside the shell/case and allows the ET-7000 to
operate at temperatures ranging from -25°C and +75°C.
I/O Pair Connection
This function is used to create a DI to DO pair through the Ethernet. Once the
