IE/PB Link PN IO

■
Application
As an autonomous component, the IE/PB Link PN IO provides a
seamless transition between Industrial Ethernet and PROFIBUS.
Using the IE/PB Link PN IO as a proxy, you can continue to use
existing PROFIBUS devices (also with PROFIsafe functionality,
V2.0 or higher) and integrate them into a PROFINET application.
The IE/PB Link PN IO also offers the following functions:
•
S7 routing
- permits cross-network PG/OP communication, in other
words, all S7 stations on Industrial Ethernet or PROFIBUS
can be programmed remotely using the programming
device
- Access can be made to visualization data of the S7 stations
on the PROFIBUS from HMI stations on the Industrial
Ethernet.
•
Data record routing (PROFIBUS DP)
- It is possible, for example, to use SIMATIC PDM (on the PC)
on Industrial Ethernet to parameterize and diagnose a
PROFIBUS field device via the IE/PB Link PN IO.
■
Design
The IE/PB Link PN IO exhibits all the advantages of the SIMATIC
design:
•
Compact design;
the rugged plastic casing features on the front:
- one RJ45 port for connection to Industrial Ethernet.
- one 9-pin Sub-D socket for connection to PROFIBUS
- one 2-pin terminal strip for connecting the external supply
voltage of 24 V DC.
- Diagnostic LEDs
•
Connection is by means of the IE FC RJ45 Plug 180 with
180° cable exit or by means of a standard patch cable
•
Simple mounting;
the IE/PB Link PN IO is mounted on an S7-300 DIN rail.
•
Can be operated without a fan
•
Fast device replacement in the event of a fault by using the
optional C-PLUG swap medium (not included in scope of
supply)
■
Function
PROFINET
•
PROFINET IO proxy;
connection of PROFIBUS DP slaves to PROFINET IO controller
with real-time property, according to PROFINET standard
Additional functionality for vertical integration
•
S7 routing
-
permits cross-network PG communication, in other words, all
S7 stations on Industrial Ethernet or PROFIBUS can be
programmed remotely using the programming device.
- Access can be made to visualization data of S7 stations on
the PROFIBUS from HMI stations on the Industrial Ethernet.
•
Data record routing (PROFIBUS DP)
- Using this option, the IE/PB Link PN IO can be used as a
router for data records that are forwarded to field devices
(DP slaves). SIMATIC PDM (Process Device Manager) is a
tool that creates data sets of this type for parameterizing and
diagnosing field devices.
Application:
It is possible, for example, to use SIMATIC PDM (on the PC)
on Industrial Ethernet to set parameters and run diagnostics
for PROFIBUS PA field device over the IE/PB Link PN IO and
DP/PA coupler.
The additional functions for vertical integration can also be used
in an existing PROFIBUS application without PROFINET for
connection to a higher-level Industrial Ethernet.
In this case, the IE/PB Link PN IO is used as an additional
DP-Master Class 2 on a PROFIBUS segment for linking to the
Industrial Ethernet and offers the above functions.
Diagnosis
Extensive diagnostic options are available via STEP 7 or SNMP,
including:
•
Diagnosis of the assigned PROFIBUS field devices;
using the IE/PB Link PN IO as a proxy, the connected
DP slaves can be diagnosed in the same manner as
PROFINET IO devices (even in the user program of the
PROFINET IO controller)
•
General diagnostics and statistics functions
•
Connection diagnostics
•
Diagnostic buffer
•
Integration into network management systems through the
support of SNMP V1 MIB-II
Configuration
STEP 7 V5.4 or higher or the TIA Portal V11.0 is required for
configuring the full functional scope of the IE/PB Link PN IO.
For the IE/PB Link PN IO, STEP 7 automatically generates the
necessary parameters, e.g. the ones that assign addresses, and
all necessary routing information.
The configuration data for PROFINET IO created with STEP 7 is
saved on the IO controller. Attention must however be paid to the
memory capacity. The initialization data for the Ethernet inter-
face is backed up on the C-PLUG (Configuration Plug) swap
media. The IE/PB Link PN IO can be swapped in the event of
failure without a programming device, because the relevant user
and configuration data is saved on the IO controller or on the
C-PLUG.
