Communication via PROFINET IO
SIMOCODE pro V PN (GP) offers communication functions via PROFINET IO with the
following features:
●
Integrated switch with 2 ports (applies to devices with 2 ports)
It is possible to build PROFINET bus and ring topologies without additional switches.
The integrated 2-port switch supports functions for port diagnostics if this functions are used
by the automation system.
●
Device replacement without removable medium/programming device
This is a function that permits replacement of a device (e.g. in case of a device defect) by a
new device with factory settings without the help of PCs or programming devices without a
memory module.
●
Shared device
Shared device is the function with which an IO device is used simultaneously by two or more
IO controllers.
This function can be used in conjunction with the fail-safe DM-F PROFIsafe digital module.
An automation system communicates with SIMOCODE pro via PROFINET IO and performs
the standard control tasks while a second fail-safe automation system via PROFINET IO can
be used for safety-related tripping using the PROFIsafe profile.
Use of this function depends on whether the automation system supports the function. It is
configured using the configuration tool of the automation system, e.g. with STEP 7 HW
Config.
●
Media redundancy
SIMOCODE pro V PN supports media redundancy according to the Media Redundancy
Protocol (MRP). This function is configured using the configuration tool of the automation
system, e.g., HW Config with STEP 7.
●
System redundancy
SIMOCODE pro V PN product version *E05* and higher and SIMOCODE pro V PN (GP)
support a redundant-system connection with two S7-400H CPUs. This provides for a
communication link (Application Relation) between each IO device and each of the two H
CPUs. The communication link can be set up by means of a freely selectable topological
connection.
This function is configured using the configuration tool of the automation system,
e.g., HW Config with STEP 7.
●
RT communication
As a motor management system, SIMOCODE pro V PN does not have any time-critical
communication functions itself but it does support PROFINET hardware RT used. The
integrated 2-port switch can therefore be used to forward RT data.
