Advanced Function Programming 3-3
SIMATIC 505–2557 Installation and Operation Guide
All
of these advanced function options are designed to be stored in the
controller in a V
-memory or K-memory table and downloaded to the module.
The advantages of this method over a communications port on the module
are greater flexibility
, easier maintenance, and reduced documentation.
The controller can change any function “on the fly” if changing process
conditions require (for example, a process needs tighter control, therefore
narrower alarm limits). Any replacement module can be downloaded from
the controller
, which eliminates the need for a cable, a laptop computer and
the most recent documentation.
Before you begin to use the advanced mode of the SIMA
TIC 505–2557, all of
the hardware functions, such as voltage range input levels, type of RTD,
_C
or
_F
, etc., should be set up in accordance with the instructions in Chapter 1
and Chapter 2.
