Application for the Web-IO Digital:
The Web-IO as FTP data logger
Often records of technical process events are required, such as:
- 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).
The following example shows the steps needed to acquire visitor numbers at a department store entry.
Configure Web-IO for FTP and create actions for writing to file
For the browser to have access, the Web-IO must already have an IP address.
To change the configuration of the Web-IO you first need to obtain the necessary access rights by entering the administrator password.
First check whether all the IP parameters are correctly configured. Especially when the FTP server is addressed using a host name it is important that both the gateway and the DNS server are entered. To do this, in the menu tree select Basic settings >> Network and there Basic network settings.
All the configuration changes must be confirmed using the Apply button.
To configure FTP access to to the menu tree and select Communication channels >> FTP.
Enter the access data for the FTP server.
In the menu tree click on Actions and then on the Add button.
Assign a meaningful name for your action and select the trigger for writing using FTP.
As the action select FTP Message and configure FTP file name and FTP text (if needed also for the Clear message). In the FTP text move the cursor to the end of the line by pressing the Enter key. Now each entry in the file will be in its own line. The <t> tag is replaced with date and time when writing to the file.
Once these steps are completed, any changes in the connected switching states are collected in one or more files chronologically.
