S5-95U, Second Serial Interface
Introduction
Introduction
The S5-95U programmable controller with second serial interface can communicate with other
devices via interface-specific functions.
In order to be able to use the performance capability of the second serial interface of the S5-95U
(SI2) in full, the user requires detailed information.
This Product Manual describes all functions which are possible at the second serial interface of the
S5-95U (SI2). It represents a supplement to the S5-90U/S5-95U System Manual. We assume
therefore that you have the S5-90U/S5-95U System Manual.
For information concerning both the S5-95U with SI2 and the S5-95U basic device, e.g.
”
installation
guidelines
”
,
”
startup and program testing
”
, refer to the S5-90U/ S5-95U System Manual. At
corresponding locations in the Product Manual, reference is made to sections in the System Manual.
Experience in installation and startup of electrotechnical plants is not necessary but helpful in order
to work successfully with this Product Manual.
On the following pages, you will find information which should facilitate handling of the Product
Manual.
Description of contents
•
Section 1
This introductory section provides an overview of the devices that can be connected to the
second serial interface of the S5-95U. You will learn which communications mechanism you
should use for your specific application and which special features are to be considered if
devices are connected to both serial interfaces of the S5-95U.
•
Sections 2, 3 and 4
In these sections, the different communications mechanisms are explained in detail by way of
examples.
•
Appendices
The appendices contain overviews for regular use, such as all DB1 parameters for SI2 and
additional information for the
”
system expert
”
, e.g. where the individual parameters are entered
in the system data area.
To make the startup phase of your system as short as possible, we recommend using this Product
Manual in the following way:
Read Section 1 since it tells you which communications mechanism is best suited to your
application
Read the relevant section on
