Function
The CP 1604 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 simultane-
ous 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 1604.
Real-time
Support of real-time properties of PROFINET for RT and IRT.
The real-time properties of the CP 1604 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 in RT mode is also available when the PC is
turned off thanks to the possibility of independently supplying an
external voltage (via "Power Supply for CP 1604").
Energy savings
Thanks to its support of PROFIenergy, CP 1604 allows for the
implementation of various energy-saving states during idle
times. By connecting an external power supply, the CP
1604 can
continue to communicate with the controller as a PROFIenergy
device, even while the PC is switched off. By connecting an
external hardware circuit, it is then possible to use this to reacti-
vate the PC via PROFIenergy mechanisms.
Software packages
DK-16xx PN IO development kit;
driver and IO-Base software for CP 1604 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 1604 is compatible with the interface for SOFTNET PN IO
•
The CP 1604 is functionally compatible to the CP 1616
Using the Development Kit DK-16xx PN IO, the CP 1604 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.
