sophisticated applications may require the monitoring of a large
number of variables in the controller
. There are a number of third party
applications available that may be used to access data from the controller
and perform statistical process control, trending, report generation and
other applications. These third party applications typically run on a PC or
other platform but most all of them communicate to the controller directly
through the program port. Often times there are multiple nodes that need to
be connected to the controller
. W
ith the PPX:505-2571 this may easily be
accomplished. See Figure 1-2.
