PC-Cards
Field bus integration for PC-based systems
|
|
Today, the PC assumes a key position in automation technology. Together with a real-time operating system,
e.g. Windows® NT, it creates an ideal hardware platform for control and visualisation of process data.
By using so called SoftPLCs the PC penetrates into application areas that have been the domain of classical
programmable controllers.
Fieldbus systems with remote input and output modules are used for the data transfer between the PC and the
automation equipment. We offer special interface cards since the PC does not feature a direct link to the
fieldbus.These intelligent cards manage the entire data transfer. Only useful data are passed onto the user
applications.
The idea behind our ‘Communication Interface’ CIF®, is to present a common access to the various
fieldbus systems available on the market. We supply a powerful, easy to handle and reliable solution at
low-cost. Thus, you can concentrate on your applications and need not 're-invent the wheel' when you are
going to use a different fieldbus system tomorrow.
We place special value on ease of operation. This includes a loadable Firmware, configuration data that
remain even with a power failure, an online RS232C diagnostic interface and LED status indicators.
Naturally, each card supplied carries the CE mark.

Field bus connection made easier
With a CIF card as a field bus Master one always obtains a current process depiction of all configured Slave
devices.
With a CIF card for a field bus Slave communication, the Dual-Port memory of the card serves as a process
depiction, which can be accessed from the field bus Master as well as from the application.
In both variants, the application program need not concern itself with the actual field bus communication as
this task is taken over by the CIF card thanks to its own communication processor.

PC cards in all formats for all fieldbus Standards
We supply PC cards with ISA- or PCI-bus, Compact PCI or in the PC/104 and PC/104P format and as PCMCIAcard
for all leading fieldbus systems. Careful component selection and concentration of the necessary functions
enable a single-sided surface mount card at a low-cost.
Fieldbuses differ from each other in their physical interfaces and capacity spectrums. We do not use plug-in
modules for adaptation. We provide a dedicated card for each fieldbus system, sometimes different ones for
Master or Slave functions. Only in this way can we guarantee you the best price/performance relationship
with the highest degree of reliability.

| System Configurator with a uniform 'look and feel'
All cards are configured using the SyCon® System Configurator. This has been coded in C++ and executes
under the Windows® 95/98/ME and Windows® NT/2000/XP operating system.
Graphical input of the individual bus participants, clearly structured menu guidance and automatic
computations of the bus parameters make the configuration a very simple exercise.
By means of the function interface, other programs can exchange data with the configurator and access its
database.
The configurator can also be included in the customer\'s own product as an OEM version.

Driver for all Windows® operating systems and Linux
We supply a 32 bit Device Driver, since you cannot access the hardware directly with modern operating
systems. This driver has the same functional interface as our drivers for DOS. Thus you can access the
Communication Interface using the same C interface for all operating systems. In addition there are drivers
for various visualisation systems and all leading SoftPLCs.
|
|
| An OPC Server for all fieldbus systems
Today, OPC is the standard interface for exchange of process data between PC applications. We supply an
OPC Server for all our PC cards. If your visualisation is functioning as an OPC client, there will be no
difference for you between the individual fieldbus systems or PC cards.
|
|
| Uniform and ‘easy to use’ application interface
The data exchange between the application and the Communication Interface takes place via a dual-port
memory. This is a type of memory where read/write accesses are performed both from the application and from
the interface side. A static data model is used for the dual-port memory. It is uniform for all cards and
contains the process image. Commands and message oriented data are exchanged using two mailboxes. The entire
handshake is performed in either polling or interrupt mode using only two bytes. This is described in
detail in our free Tool Kit and illustrated by example programs. Thus, you are able to code your drivers
in the shortest possible time.
