Overview
DP/AS-i F-Link
The DP/AS-i F-Link is a compact, safety-related router 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 61508/EN 62061.
•
Connection of up to 62 AS-Interface slaves
•
Supports all AS-Interface master functions in accordance with
AS-Interface Specification V3.0
•
Typically easy transmission of non-safety-related input/output
data of all AS-i slaves
•
Integrated analog value transmission
•
Direct integration in PROFIBUS networks
•
Local diagnostics using the LEDs and display with control
keys
•
Sturdy and narrow plastic enclosure in degree of protection
IP20 for mounting on a standard mounting rail or wall mount-
ing (with an adapter)
•
Fast device replacement in the event of a fault
Note:
Alternatively to the DP/AS-i F-Link, a powerful, safety-related
router between PROFIBUS (or PROFINET) and AS-Interface
can be set up by combining the CM AS-i Master ST and
F-CM AS-i Safety ST modules in an ET 200SP station,
see pages 2/36 to 2/42
.
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 is 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.
See "More Information" on page 2/51
.
Configuration
The DP/AS-i F-Link is configured as follows:
•
With STEP 7 version V5.4 SP1 and higher: 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 also possible.
•
The DP/AS-i F-Link does not support AS-i safety output
modules.
•
The DP/AS-i F-Link cannot be configured with TIA Portal.
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 SINUMERIK Safety Integrated
The safety and standard range can access the digital and ana-
log I/O data of the connected AS-Interface slaves directly
through the I/O address space of the CPU.
Operating conditions:
•
In the case of an AS-i communication error (e.g. failure of
an AS-i standard slave or ASIsafe slave), the DP/AS-i F-Link
sends the substitute value "0" to the F controller for all safe
inputs.
•
No safe AS-i outputs can be operated on the AS-i line of the
DP/AS-i F-Link.
•
Safe control of actuators is handled by the
F controller, e.g. via safe SIMATIC output modules.
•
The DP/AS-i F-Link is not suitable for AS-i Power24V.
