IP 265 Preface
Preface
The IP 265 represents an innovative enhancement of the processing power of the PLC
(PLC=Programmable Logic Control). It is a powerful, freely programmable I/O module and a
member of the range of I/O modules common to the S5-100U, S5-90U/S5-95U and ET 200U
(distributed I/O system).
On the worldwide market of mini and micro PLCs, there is a growing tendency towards faster and
smaller components. In the case of existing mini PLCs of the SIMATIC S5 family, system-dependent
limits are set by processing speed of control commands. The conventional SIMATIC C1, C2, C3
circuitry is therefore still used for expecially fast applications. With this technology, hardware
connections which enable high-speed sub control but are not reversible in the sense of
"programmable" are set up by means of electrical wiring (solder bonds).
The use of FPGA technology in the IP 265 makes it possible for the first time to meet high speed
requirements for sub controls of an overall system with a freely programmable SIMATIC S5
module. Hardware connections are also set up on the IP 265 by loading memory contents into an
FPGA (Field Programmable Gate Array). The hardware connections established in this way enable
parallel and therefore fast sub control of an overall system. The FPGA used in the IP 265 also has
the advantage that the sub control can easily be modified by renewed loading of FPGA-relevant
data.
A special user program (IP 265 user program) must be loaded into the IP 265. There are two
options:
• A program generated to suit specific user requirements or
• Fixed-programmed standard software from Siemens
A special COM (COM 265) is available for free programming of the IP 265.
In addition to the programmable application, the IP 265 also offers the possibility of implementing the
special "timer" function by means of a standard program. Siemens offers a memory submodule with
the standard function counter for the IP 265. It is supplied separately and is not described in this
manual.
The program capacity of the FPGA used in the IP 265 is limited. The IP 265 is therefore used for
high-speed sub controls. More complex sub processes can be controlled with the IP 265 by adding
a further IP 265 module.
Note
In the manual, Section 13 "Sample Applications and Programming Aids" is reserved for program
examples. It enables fast startup of the module without having to read the entire manual.

IP 265 Introduction
Introduction
Before you continue, you should read the introduction carefully. This facilitates use of the manual
and saves time.
To use the IP 265 optimally, you need detailed information.
In the manual (GHB), we have attempted to present this information as completely and as well
organized as possible. At the same time, we have attempted to meet the increased demands placed
on technical documentation. This means in particular:
• Standardization of the vocabulary and notation
• Extensive organization
• Visualization of individual topics
• Customer-oriented layout of the contents
In this way we would like to provide the information necessary for working with the IP 265 to both
inexperienced as well as experienced SIMATIC S5 users.
Description of contents
This manual represents a comprehensive description of the IP 265. It can be divided into individual
thematic blocks.
• Description (Sections 1 and 2)
- The "System Overview" informs you of the functions the module can handle and how it is
used in the S5-100U, S5-90U/95U and ET 200.
- The "Technical Description" provides general information on the interfaces of the module,
information on the pin assignments and technical specifications.
• Assembly and connection buildup (Section 3)
- The "Installation Guidelines" provide you with all the information you need to assemble the
module and link it with the process I/O. Furthermore, you are informed of the voltages the
IP 265 must be supplied with during normal operation.
• Mode of operation (Sections 4 to 7)
- We describe here generally how the module works in its system environment, giving you
information on parallel program execution and addressing of the IP 265 as well as control of
IP 265 program execution by the CPU. Using a function model, we will demonstrate the basic
user actions required for starting up the IP 265.
• Working with COM 265 (Sections 8 to 11)
- These sections give a detailed description of the necessary user inputs during startup of the
IP 265 with the aid of COM 265. It shows how the module functions are defined, simulated
off-line and tested on-line.
• Expansion (Section 12)
The expansion of two IP 265 modules is a special case. Module expansion is dealt with in a
separate section of this manual.
