Overview
DP/AS-i F-Link
The DP/AS-i F-Link is a compact, safety-related network transi-
tion between PROFIBUS (DP Slave) and AS-Interface, with the
following features:
•
Monitoring the inputs of safety-related digital AS-i slaves
(ASIsafe slaves) and forwarding of data through PROFIsafe.
No additional safety-related components required for the
AS-Interface (e. g. MSS ASIsafe Modular Safety System)
•
Can be used up to PL e according to EN ISO 13849-1 and to
SIL 3 according to IEC 62061/IEC 61508.
•
Connection of up to 62 AS-Interface slaves
•
Supports all AS-Interface master functions according to
the AS-Interface Specification V3.0
•
Typically easy transmission of non-safety-related input/output
data of all AS-i slaves
•
Integrated analog value transmission (all analog profiles)
•
Direct integration in PROFIBUS networks.
Optional integration in PROFINET environments through
PROFINET/PROFIBUS gateway (IE/PB Link PN IO) or through
SIMATIC S7-315/317/319 F PN/DP or S7-416F-3 PN/DP
•
Connection to ET 200S with IM-F-CPU using DP master
module is possible
•
Optimum TIA integration in STEP 7 using Object Manager,
integration in non-Siemens engineering tools using
PROFIBUS GSD file
•
Local diagnostics using LEDs and display with control keys
Design
•
Rugged, slim plastic enclosure, degree of protection IP20, for
standard mounting rail or wall mounting
(with adapter)
•
Compact design:
-
LEDs in the front panel for indicating the operating state and
functional readiness of all connected slaves
- 2 buttons on the front for start-up and call-up of diagnostics
information
- 4 LEDs for display of the operating state of the device, of
PROFIBUS DP and the AS-Interface network
- Front PROFIBUS DP connection with sub D connector
- Removable terminal blocks for connection of AS-i +/- and
control supply voltage (over 24 V DC PELV power supply
unit)
- Narrow width (45 mm)
•
Operation without fans and batteries
•
Fast device replacement in the event of a fault
Functionality
Communication principle
The PROFIBUS DP master or the safe control communicates
with the AS-Interface slaves over the DP/AS-i F-Link.
The AS-Interface process data are mapped in different data
areas for non-safety-related input and output data and safety-
related input data.
Diagnostics
Extensive diagnostics is possible using the four LEDs, display
and control keys or SIMATIC S7. Further details can be found in
the manual.
Configuration
The DP/AS-i F-Link is configured as follows:
•
With STEP 7 as of Version V5.4 SP1: In particular, Siemens
AS-Interface slaves can be conveniently configured via the
slave selection dialog.
•
Uploading the actual configuration of an already configured
AS-Interface network in a STEP 7 project is possible.
•
Alternatively, DP/AS-i F-Link can be integrated by means of
the PROFIBUS GSD file in the engineering tool
As a startup aid, it is also possible to adopt the ACTUAL
configuration in the appliance storage device directly on the
appliance to activate the AS-interface slaves.
Programming
In contrast to the MSS ASIsafe Modular Safety System, the
DP/AS-i F-Link is a pure gateway, which does not run through its
own safety logic. Programming of the safety function is imple-
mented at the level of the higher-level fail-safe PLC, e. g.:
•
With Distributed Safety, Version V5.4 SP1 or higher for
SIMATIC S7-300F/416F
•
With the SAFETY INTEGRATED "SI-Basic" or
"SI-COMFORT NCU" software for SINUMERIK 840D pl/sl
The safety and standard range can access the digital and
analog I/O data of the connected AS-Interface slaves directly
through the I/O address area of the CPU.
