|Modular system of industrial input/output devices DataLab IO allows users to configure numbers, types and directions of measured and controlled signals to perfectly fit the particular application. All DataLab IO devices contain universal CPU core, to which are attached various I/O modules according to signal type (analog and digital inputs and outputs, counter inputs, relay modules, modules for platinum thermometers etc.). There are CPU cores for one, two and four I/O modules available. CPU cores with USB interface offer very easy application (USB is Plug-and-Play), simple connection with standard USB cable, the possibility to power the device through the same cable and fully automatic configuration. The disadvantage of USB connection is limited length to 5 m. This disadvantage is completely eliminated by new CPU core for four modules with 10/100 Mbit Ethernet interface.|
CPU core of DataLab IO/ETH with Ethernet interface is fully compatible with all I/O modules of DataLab IO system. Only the USB 2.0 interface is replaced with 10/100 Mbit Ethernet interface and the device communicates using TCP/IP protocol.
There is no difference between USB and Ethernet connected DataLab IO devices from the application point of view. It is enough to specify means of communication in the device driver parametric file. The rest of application sees no difference.
[device] type = ethernet ip_address = 192.168.0.3 remote_port = 10250 local_port = 40230 ip_timeout = 500 con_timeout = 500 password = 12345
The DataLab IO offers HTTP server for the configuration. No special software is used to configure the device, standard WWW browser is enough.
Because WWW server traffic handling consumes significant resources on the small device and it is also not desirable to configure the device anytime from any accessible WWW browser, the HTTP server in the device is run only when the device is turned on with Reset button pressed. Only the it is possible to set parameters through WWW browser. When the device is powered on normally, HTTP server does not run and the device responds only to requests to read and write technology signals.
One of the device configuration parameters is password. The communication between each computer and the DataLab IO/ETH device is encrypted, which eliminates unauthorized reading of technological data or controlling of the technology from other computers within a computer network.
