Function Modules
The IP 265 High Speed Sub Control is a powerful, user-programmable I/O module which relieves the
CPU's of the SIMATIC S5-100 systems of automation tasks which place great demand on speed
and reproducibility.
A separate manual is available for the IP 265. It can be ordered under the order number 6ES5 998-
5SH21.
Function
The IP 265 High Speed Sub Control is available with a COM software package which is required to
determine the function of the module.
The use of the IP 265 in an S5 system enables rapid I/O processing in the millisecond range. By
implementation of an FPGA (Field Programmable Gate Array) in the IP 265 it is possible to process
process signals in parallel and very fast.
The IP 265 user program consists of elementary basic functions such as logic operations, counters,
timers or comparators. The structure of the IP 265 user program is based on the CSF5 type of
representation.
The following can be used:
• Either a user-programmed user program
or
• a fixed-programmed standard program from SIEMENS.
The COM 265 is available for user-programming of the IP 265. Besides it being programmable, the
IP 265 can also be used to implement the special "counter" function with a fixed-program standard
program. For this purpose, SIEMENS AG offers a memory submodule for the IP 265 with the
standard "counter" function.
The IP 265 user program is automatically processed by the IP 265. It conditions process input
signals to process output signals. The IP 265 can read 11 process inputs (8 x 24 V inputs, 3 x 5
differential inputs) and set 8 process outputs (24 V outputs).
The program capacity of the FPGA and the number of process inputs/outputs of one IP 265 are
limited. The IP 265 is therefore used for rapid sub controls. By adding one IP 265 to another,
complex sub-processes can be controlled with this module.
Installation
As other I/O modules, the IP 265 High Speed Sub Control is mounted on a bus unit.
Adressing
The module is addressed like a 4-channel analog module.
