9.1 ASM 452
9.1.1 Application area
The ASM 452 interface module is a MOBY module for operating MOBY components over
PROFIBUS DP-V1 on
● Any computers and PCs
● Any PLCs
When operating the interface module on a SIMATIC S7, function blocks are made available
to the user.

9.1.2 Features
The ASM 452 is the result of consistent development of the familiar ASM 450 interface
modules. Optimal data throughput can be achieved even in large-scale PROFIBUS
configurations thanks to the use of acyclic data traffic on PROFIBUS DP V1. The minimum
cyclic data load of the ASM 452 on the PROFIBUS DP provides the user with the guarantee
that other PROFIBUS nodes (e.g. DI/DO) can still be processed at great speed.
The ASM 452 is an interface module for communication between PROFIBUS DP and the
SLG D1xS with RS 422. The data on the MDS D139/D160 can be physically addressed
("standard" addressing) through the ASM 452.
In SIMATIC S7, FC 45 is available for "standard" addressing.
The FC 45 provides the S7 user with an interface with powerful commands that is easy to
operate. FC 45 also offers command concatenation (not with SLG D11S ANT D5 and
SLG D12S) and S7 data structures with UDTs.
