Program; Operating The Command Interface Of The Ie/As-Interface Link Pn Io As-Interface Master - Siemens SIMOTION Function Manual

Program

3.1 Operating the command interface of the IE/AS-Interface Link PN IO
AS-Interface master
Overview
The command interface of the IE/AS-Interface Link PN IO AS-Interface master is operated by
means of data record transfer.
Data record transfer
Data record transfer is performed in the SIMOTION system using the functions _readRecord
and _writeRecord. In terms of their functionality, these correspond to system function blocks
SFB 52 and SFB 53 in the SIMATIC system (see the table below).

RECORD
Parameter ioId is parameterized as type Input (for addresses in the I/O input range) or Output (for addresses in the I/O
1)
output range). Diagnostic addresses are always of type Input. Two identical ID-logic addresses may be in both the input
and output range.
Note
Data record transfer using _readRecord or _writeRecord is shown in the application example
for FB _ASI_cmdInterface.
The application example is included on the "SIMOTION Utilities & Applications" CD-ROM and
is available for various SIMOTION hardware platforms. The "SIMOTION Utilities &
Applications" CD-ROM is provided free of charge and is part of the SIMOTION SCOUT scope
of delivery.
