PROFINET/Industrial Ethernet
Communication for PC-based systems
CP 1616

■
Function
The CP 1616 can be operated as a PROFINET IO controller and/
or PROFINET IO device that stores the process image (input and
output data) in the memory area on the CP. With simultaneous
controller and device mode, only the controller or the device can
be operated in IRT mode. High-performance data transfer to and
from the IO devices is performed autonomously by the CP 1616.
Real-time
Support of real-time properties of PROFINET for RT and IRT.
The real-time properties of the CP 1616 ensure extremely short
cycle times with highly accurate clock-pulse rates.
Switching
According to the industry requirements, the 4-port real-time
switch additionally permits the configuration of line topologies
with spur lines and makes external switch components unneces-
sary.
The switch function is also available in RT mode when the PC
is turned off thanks to the possibility of independently supplying
an external voltage.
Energy savings
Thanks to support from PROFIenergy, it is possible to implement
various energy-saving states during idle times on the CP 1616.
Software packages
DK-16xx PN IO development kit;
driver and IO-Base software for CP 1616 as PROFINET IO-
Controller and IO-Device under Linux in source code for transfer
to any PC-based operating systems with IO-Base interface for:
•
PROFINET communication:
- PROFINET IO controller:
Connection of field devices to Industrial Ethernet with
PROFINET
- PROFINET IO device:
Link-up with a PROFINET IO controller through real-time
communication according to the PROFINET standard
•
Access in isochronous mode to real-time data for
PROFINET over IRT;
extremely short cycle times with highly accurate clock-pulse
rates;
jitter accuracy, isochronous mode, and cycle time enable
high-performance motion control applications.
•
Direct memory access to the process data;
the process data of the IO-Devices are always consistent.
The IO programming interface provides the PC programmer
with function calls for data transfer.
•
The design of the interface not only permits fast access as a
PROFINET IO controller, but also easy transfer to other
operating system environments (e.g. VXWorks, QNX, RMOS,
RTX).
•
The IO-Base interface for the PROFINET IO controller of the
CP 1616 is compatible with the interface for SOFTNET PN IO
•
The CP 1616 is functionally compatible with the CP 1604
Using the Development Kit DK-16xx PN IO, the CP 1616 com-
munications processor can be integrated into any PC-based
operating system environment. The Development Kit contains
the driver and IO-Base source code required for this including
the transfer instructions and also the example code which
executes with SUSE Linux.
User interfaces
Programming interface through C library
For applications that want to use the PROFINET IO-Controller or
IO-Device functionality directly over C/C++, the IO-Base inter-
face can be used. This interface is of a similar design to the
DP
Base interface of PROFIBUS modules CP 5613 and CP 5614.
It is therefore possible to port existing PROFIBUS DP master
applications to PROFINET IO-Controller applications.
Diagnostics
Extensive diagnostic options are available via STEP 7 or SNMP,
including:
•
General diagnostics functions
•
Connection diagnostics
•
Diagnostics of the assigned PROFINET field devices
•
Integration in network management systems through the
support of SNMP
Configuration
Configuration of the CP 1616 is performed with STEP
7/NCM PC,
V5.3 SP2 and higher. NCM PC is included with the module.
