Application for the Web-IO Digital:

The Web-IO as FTP data logger


In many cases logging of the progress of technical processes is needed:

  • When was a door opened, and when was it closed again?
  • How often was the beam of a photoelectric sensor interrupted during a particular time interval?
  • How long did a motor run?
  • ............

Increasingly stringent quality requirements demand increasingly precise operational data acquisition. But even independent retail establishments are becoming more interested in recording and evaluating data on customer frequency.

With the Web-IO Digital you can write such data to a file along with a time stamp using FTP (File Transfer Protocol).

Control with Visual Basic

The following example shows the steps needed to acquire visitor numbers at a department store entry.

You don’t have a Web-IO yet but would like to try the example out sometime?

No problem: We will be glad to send you the Web-IO Digital 2xInput, 2xOutput at no charge for 30 days. Simply fill out a sample ordering form, and we will ship the Web-IO for testing on an open invoice. If you return the unit within 30 days, we will simply mark the invoice as paid.

Preparations

You have already provided your Web-IO Digital

Configuring the Web-IO

To change the configuration of the Web-IO you first need to obtain the necessary access rights by entering the administrator password.

Configuring digital IOs

All the basic settings necessary for using FTP can be made from a clearly organized configuration page in the browser.

Digital SNMP

Depending on the Web-IO model you can define up to 12 alarms which trigger writing to various log files. Not only the status of the inputs and outputs but also a specified time frame can be triggers for the alarm.

TCP Client

The structure of the log file can be varied over a wide range depending on the application.

Port Number

Then the settings are saved in the Web-IO.

Session Control

The Web-IO thus becomes a data logger, and in the same manner you can also record machine run times, quality data and other processes over time.
