Seneca Z-LWS, PLC Unit

Description:

The Z-LWS is a Micro PLC, it features a RS485 serial port, two RS232 port and an Ethernet port. Such connectivity makes it ideal for remote control of the device using the internet or a local network whilst being part of a SCADA system or other ModBus RTU Network.
The Z-TWS has a powerful 32-bit RISC microprocessor making it powerfull enough to replace almost any PLC. The Z-TWS has a built-in web server (located in it's 16 MB Flash and 8 MB Ram memory) allowing remote supervision and control of the device (resetting, parameter variation and maintenance) via the internet or a local network.
