Introduction - Siemens SIMATIC S5 Manual

IP 265

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.
