The various TELEPERM M automation systems have different
designs, ranges of functions and performances. The AS 235,
AS 235 H and AS 235 K automation systems described in this
catalog are proven and reliable. They can be configured within
wide limits and coupled to a wide range of subordinate systems.
The AS 235 H additionally has a redundant central unit and thus
satisfies particularly high availability demands. The AS 235 systems
can communicate with one another and with higher-level
systems via the TELEPERM M CS 275 plant bus.
A wide range of TELEPERM M input/output modules is available
for connection of the process peripherals (sensors and final control
elements) to the AS 235, AS 235 H and AS 235 K automation
systems. Some modules have their own processing features or
can be configured application-specific.
The AS 388/TM and AS 488/TM automation systems (see Catalog
PLT 112) use the SIMATIC M7-300 and M7-400 automation
computers as the hardware platform and are compatible with the
AS 235 system. They are appropriate for the extension of existing
TELEPERM M systems or for the design of new systems.
The AS 388/TM and AS 488/TM systems can be operated on the
PROFIBUS-TM plant bus. PROFIBUS-TM is based on the standardized
PROFIBUS. The AS 488/TM system can additionally be
operated on the CS 275 plant bus.
ET 200M distributed I/O systems with a comprehensive range of
I/O Modules can be connected to the AS 388/TM and AS 488/TM
systems via one or two PROFIBUS-DP interfaces. Siemens Teleperm Programmable Controller Siemens Teleperm Programmable Controller Xiamen The Anaswers Trade Co,.LTD , https://www.answersplc.com
