SIMATIC ET 200M 25
Interface modules for PROFIBUS and PROFINET
The various S7-300 modules in the ET 200M distributed I/O
system are connected to the bus system via the interface
module – either to the proven PROFIBUS fieldbus or to
PROFINET, the open Industrial Ethernet standard.
The following interface modules are available:
IM 153-1

IM 153-2 HF

1)
The integral 2-port switch of the IM 153-4 now also permits the problem-free
setup of linear structures in addition to star topologies.
2)
Changes to digital inputs are tagged with a time stamp locally (in the IM 153
of the ET 200M) and transferred to the CPU by means of a process interrupt.
3)
Isochrone mode is the synchronized coupling of distributed I/O and the user
program on PROFIBUS with a constant cycle time. In this manner, actual value
sensing and setpoint output are performed synchronously and with a constant
cycle time and with consistent data images.
4)
The "electronic rating plate" or identification data are the data stored in a mo-
dule such as the Order No., release date, installation date or plant ID-code that
uniquely identify this module and which are available online, for example, to
simplify fault rectification.
