Configuration Limits

7.5.1

Minimum Configuration

The minimum configuration is used when you only configure the station proxy
(DAP).
In this case, the application does not include any user data. The length of the
application data is zero.
The provider telegram contains the provider status of the submodules for
Interface, Port 1, Port 2 and station proxy (DAP). The provider telegram length is
64 bytes.
The consumer telegram contains the consumer status of the submodules for
Interface, Port 1, Port 2 and station proxy (DAP). The consumer telegram length
is also 64 bytes.
7.5.2

Maximum Configuration

Due to one of the following boundary conditions, you can achieve the maximum
configuration:
•
Maximum of 250 modules or submodules
•
Maximum input data length of 512 bytes configured
•
Maximum output data length of 512 bytes configured
•
Maximum provider data length of 736 bytes in the real time telegram
exhausted
•
Maximum consumer data length of 736 bytes in the real time telegram
exhausted

Flexible Configuration of Digital I/O Modules

7.6.1 Packaging Information from Digital Input and Output
Modules
Digital input modules and/or digital output modules occupy a data volume of 1 or
2 bits per channel in the process image. Depending on the number of channels, the
scope of the process data of the respective I/O modules ranges from 2 bits to 2
bytes.
Data management of processing systems such as PCs or controllers is normally
byte-, word- or double word-oriented.
To ensure processing on these systems is as efficient as possible, you can flexibly
arrange process data from digital input modules and digital output modules in
byte, word or double word data structures. This can be accomplished by using
corresponding submodule types in the configuration:
