IPC monitoring for TwinCAT users: access via the PLC
There are many standard scenarios for the monitoring of an IPC within a manufacturing facility and, for this reason, also
many different types of software that can be installed as a separate application on the IPC. The advantage of a system-
integrated solution from within the PLC is quite clearly the familiar working environment of a TwinCAT user. Without further
familiarization, limit values can be specified within TwinCAT and SMS messages can be generated. If an appropriate parameter
is read out cyclically by a function block, then the display of a message upon exceeding a limit value requires only one further
function block. Access via TwinCAT is supported from version 2.11 onwards.

IPC monitoring without TwinCAT: access via interfaces
IPCs and Embedded PCs from Beckhoff are not necessarily linked to TwinCAT; therefore, the use of the diagnostic and
configuration interface is not coupled to TwinCAT. The interface is structured according to a uniform layer and is independent
from the installed operating system and the employed hardware and programs. The individual hardware, software and
application parameters are rasterised and can be accessed without TwinCAT by means of standard interfaces, such as a
webpage, (see fig. 4).
