IP 265
1 System Overview
Intelligent I/O modules extend the field of application of SIMATIC S5 programmable controllers. They
are technology-oriented and offload the central processor in the CPU.
The IP 265 is an extremely powerful I/O module. Use of the module in an S5 system permits fast I/O
preprocessing through parallel program scanning.
For complex applications, only one fast sub process of an overall system is controlled by the IP 265.
For this purpose, the sub process must be transfered from the CPU (CPU user program) to the
IP 265 (IP 265 user program).
IP 265 has the following performance characteristics:
• Recording of fast processes (e.g. counting)
• Control of fast processes (e.g. control of stepper motors)
• Short response times (e.g. fast disconnection of actuators)
• Data exchange with CPU user program (e.g. assignment of sub control parameters (IP 265))
The module can be used with the CPUs of the following S5 systems:
• S5-100U (CPU 100 from 6ES5 100-8MA02, CPU 102 from 6ES5 102-8MA02 or CPU 103)
• S5-90U/95U
• ET 200U (IM 318-B from version 2)
Restriction: The IP 265 can
- only be loaded from memory submodule,
- only be operated in Slow mode in the ET 200U.
The S5 system forms the environment of the IP 265 during operation of the module.
Programming and startup of the IP 265 are carried out by means of COM 265 at the programmer. In
principle, COM 265 can also be loaded on a PC.
Convention
All S5 systems with which the IP 265 can be used are commonly denoted as "S5 100" in this
manual.
