GW-IMP-WEB-1-S Count Pulse Datalogger MODBUS RTU

MarCom

Datalogger web pulses counter Code: GW-IMP-WEB-1-S Version 6 inputs without Ethernet

Datalogger web pulses counter The web datalogger pulses counter is able to count the pulses on the digital inputs (2 by default expandable). Through the web interface (RNDIS protocol) it is possible to display count values, change the pulse weight and enter an offset in the event of misalignment or assembly after the installation of the counter. All data can be viewed via the web interface or reachable via MODBUS RTU connection.

The datalogger as optional feature can be ordered time triggered recording of the counters on csv files in the internal memory or in a SD card. Files can be downloaded via ftp Server functionality.

Change connection settings To change device settings you need to connect it to a PC using the USB port.

The physical connection between the PC and the PLC must be done with an USB cable A to mini-B type. This connection uses the Microsoft RNDIS protocol, which creates a virtual Ethernet port on the PC. When the device is connected to the PC for the first time the system will detect the new device and install the RNDIS driver. The operations for setting the IP address on the PC are as follows (Windows 7): 1. On Start, click Control Panel; 2. On Control Panel, double-click Network and Sharing Center;

3. The active network connection list window will open; click on the highlighted link 4. The connection status window will open; click on Properties 5. The properties window of the RNDIS connection will open: select Internet Protocol version 4 (TCP/IPv4) and then properties 6. The properties window of the selected Internet protocol will open: set an IP address compatible with the address of the device to connect to.

Web visualization To view the web pages containing the data, it is necessary to connect the data logger to the Ethernet network through the RJ45 port. On a web browser just enter the default address: 192.168.1.122; If you do not connect, check that you have an address on the network card of the computer on the 192.168.1.X subnet. (see section "Change connection settings").

This way you get to the main screen of the data logger with the values of the counters.

From this page, through the links at the top of the page, you can access the following pages: - Setting datalogger; Page to set the pulse counter parameters, such as pulse weight and count offset.

- Hardware setup; Page to modify the hardware parameters of the pulse counter as IP address and Modbus communication parameters.

- Time setup; Page to change the time or activate the NTP protocol.

- System; Page to log in to enable changes and to reboot the system.
