Write/read devices with RS422 interface
7.1 Overview SLG with RS 422 for SIMATIC S7 and PROFIBUS DP-V1
Application area
The SLG D1xS provides inductive communication with the mobile data storage units (MDS)
and serial coupling to the interface modules (ASM).
A range of different SLGs are available for small, medium and large distances to the MDS
meeting all customer requirements.
● SLG D10S with
● SLG D11S with
● SLG D12S with integral antenna
● SLG D12S with integral antenna (plug-in version)
The rugged housing and high degree of protection (IP65) permit use even under the
toughest industrial conditions.
Design and function
The SLG implements the commands received from the interface module. These commands
and the data to be written or read are processed by a corresponding modulator/demodulator
circuit.
Communication between the MDS and SLG is performed over an inductive alternating field.
The transmittable quantity of information between SLG and MDS depends on:
● The speed at which the MDS moves through the transmission window of the SLG
● The length of the transmission window
● The MDS type
