Settings
Only a limited number of data bytes per module can be transmitted consistently through
PROFIBUS. If the number of data bytes of a module is even, up to 128 bytes can be transmitted
consistently. If the number of data bytes is odd, up to 63 bytes can be transmitted consistently.
Note that the data of a certain module cannot be transmitted consistently if you exceed these
limits.
Settings
Below the module and value list general settings can be configured:
Slave Address If you have several Edge gateway devices with different configurations in your PROFIBUS network, the
Download GSD file
Through the Download button, you can download the GSD file including a corresponding graphic
file. The GSD file can be imported into the PROFIBUS Master. It includes the modules and values
defined above.
Acyclic data access
The defined modules and their values can also be accessed acyclicly. Modules can only be
accessed in a whole. It is not possible to access individual values. Modules are not addressed
through slot numbers. Instead requests must always go towards slot 1 and the index determines
the module ID. So if you want to access module 6, send a request with slot number 1 and index 6.
Several Anybus Edge devices in the same network
If you want to use several Edge gateway devices in your PROFIBUS DP network and these don't
have the same configuration, you should do the following:
• Don't use the same module ID on different Edge gateway devices.
• Export the GSD files of all Edge gateway devices.
• Merge the GSD files into one. The files will be the same except for the module entries. Copy
all module entries into one GSD file.
• Use the merged GSD file for all devices, but only use the modules that have been configured
on the corresponding Edge gateway device.
Event Log Messages
The following section describes the messages that the PROFIBUS DP Slave driver may log to
the Event Log. All messages are prefixed with the text Anybus CompactCom driver (EXT09):.
• PROFIBUS DP module detected
An Anybus CompactCom module of PROFIBUS DP type has been detected.
• Resetting Anybus CompactCom module
The Anybus CompactCom module will be reset - either due to an error or due to a request
from the network.
• Received illegal floating point value
An illegal floating point value has been received from the network.
• Anybus CompactCom base driver error. (Error code <error code>, Info <information code>)
An error occurred in the base driver for the Anybus CompactCom module. This should not
happen. Please contact the customer support.
Anybus Edge Gateway Reference Guide
PROFIBUS Master must be able to distinguish these devices. Thus they need to have different Slave
Addresses. You can chose a Slave Address between 2 and 125.
