A free analog or ISDN telephone terminal is all you need to connect the Web-IO 12 x Digital Dial to the Internet through a modem. The Web-IO can be dialed up or independently connect to the provider, for example to send e-mails. At the same time the Web-IO can be incorporated into a local network through the Ethernet terminal. In this way for example you can integrate the Web-IO into an Intranet application and at the same time carry out remote access over the Internet or telephone network. Special programming expertise such as is generally required by PLC-based solutions is not needed.

Four mutually combinable base modes are available for reading or writing to the in-/outputs:

Sending alarms
When a door contact is actuated, for example, the Web-IO automatically dials up the Internet through a provider and sends e-mails to one or more recipients. In parallel with the e-mail service SNMP, syslog or pure socket connections via TCP or UDP can be used for sending alarms.

Operating and controlling the Web-IO over the Internet
A wakeup call in the form of a short dial-up of the call number of the Web-IO causes the latter to dial the Internet through a provide. All the usual services, from simple browser access to your own socket application, are then available for accessing the device. To enable operation with economical standard Internet entry points with IP addresses that change each time you dial, the Web-IO offers integrated support of dynamic DNS services (e.g. www.DynDns.org)

Direct dial-in to the Web-IO
Applications which for security reasons for example prevent communication over the Internet dial directly into the device for access to the I/Os. Such direct access is set up in the same way as access to your Internet provider. You simply replace the dial-up number with that of the Web-IO.

The digital in- and outputs are configured using industry-standard 24V technology. In many cases relays may not even be needed. The broad input voltage range also allows 12V operation.
