Z-TWS-02, Control Unit - PLC/RTU/Web Server/Datalogger/Bridge

Description:

The Seneca Z-TWS-02 is a PLC/Web Server/RTU/Datalogger module equipped with a RS485 serial port, two RS232 interface ports and an Ethernet port, the device can be integrated to a ModBus Network and be accessed, controlled and supervised remotely via the Internet or a Local Network thanks to Z-TWS's built-in web server (located in it's 16 MB Flash and 8 MB Ram memory).
The Z-TWS's 32-bit RISC microprocessor makes it powerful enough to replace almost any PLC.
Also part of the device is a data logging function of the systems signals and/or status which can be subsequently used for analysis and control of the devices operations, the Z-TWS can also be used as a RTU (Remote Terminal Unit).
