Siemens ASM 456 Operating Instructions Manual page 8

Description
Features
The ASM 456 provides simple connection technology. Optimum data throughput can be
achieved through acyclic data traffic on the PROFIBUS DP V1 even when using large
PROFIBUS configurations. The minimum cyclic data load of the ASM 456 on PROFIBUS
provides the user with the guarantee that other PROFIBUS nodes (e.g. DI/DO) can still be
processed at great speed.
Up to 2 readers can be operated at the same time on the ASM 456. This allows you to start a
command at the same time on 2 readers (using the corresponding FB/FC).
The transponder data is accessed using the physical addressing of the transponder. In
SIMATIC S7, the FBs 45/55/101/116/132 and FC 56 as well as the Ident profile are available
for this purpose. The functions provide the S7 user with a simple-to-use interface with
powerful commands (processing one complete transponder with one command; command
linking; S7 data structures using UDTs).
The MOBY filehandler is also implemented on ASM 456. The file handler is a file
administration system similar to DOS for the Ident system MOBY I/U and RF300. It consists
of one program which is executed on the interface module. For the SIMATIC application FC
56 and the RFID standard profile (S7) are available.
Other features
● Degree of protection IP67
● System integration with ECOFAST or M12, 7/8" concept
● T functionality, that is, a component can be replaced without adversely affecting other
modules with regard to bus communication and voltage supply
● Standardized PROFIBUS user interface for Ident technology with Ident profile
● Firmware update
● PROFIBUS interface module up to 12 Mbit/s with automatic transfer rate detection
● Parameterizable device-related diagnostics data with text display
● Support for I&M functionality:
A mechanism for reading out information via the module and saving system information
such as function, installation date, installation location, and comments.
● Master redundancy supported when operation is on Y link
● Operation on SIMOTION via SCOUT V4.0
You will find detailed information on this in the function manual SIMOTION, Standard
