SOAP
= Simple Object Process Protocol
SOAP is a simple extensible protocol for
exchanging information in distributed
environments. It defines XML messages that
can be exchanged between heterogeneous
applications via HTTP.
SOAP is independent of operating systems and
can be integrated into existing Internet
structures, including Ethernet TCP/IP-based
automation concepts. SOAP is based on Remote
Procedure Calls and XML. This means that
functions from other platforms can be called
and used from any point within the network.
Any results data can also be returned using
XML schemas. This enables distributed
computing capacity and non-redundant data
storage in distributed systems.
Switch-off time
The switch-off time is the time between the
control current being switched off and the
output voltage falling to 10% of its original
value.
TCP/IP
= Transmission Control Protocol/Internet
Protocol
TCP/IP is a family of network protocols and
therefore often just referred to as Internet
protocol. The computers that are part of the
network are identified via their IP addresses.
UDP is another transport protocol that belongs
to the core group of this protocol family.
Trigger
A trigger is a pulse or signal for starting or
stopping a special task. Triggers are often used
for controlling data acquisition.
UDP
= User Datagram Protocol
This is a minimal connection-free network
protocol which is part of the transport layer
within the Internet protocol family. The
purpose of UDPs is to ensure that data
transmitted over the Internet reach the correct
application.

Watchdog
A watchdog is an electronic delay switch used
to monitor key components or devices. It is
activated periodically and triggers an alarm
after a specified time. If the unit to be
monitored is working correctly, the watchdog
is reset before triggering the alarm.
