AN-X to AN-X Communication
An AN-X module can be configured to exchange data with other AN-X
modules over Ethernet.
Each AN-X can produce from 1 to 10 blocks of data. Each block can
contain up to 1400 bytes of data. You map PROFIBUS data to the
produced blocks in a spreadsheet or comma-separated variable (CSV)
text file, then send the configuration to the AN-X using the web
interface.
Produced data blocks update at timed intervals, from 5 to 16383 ms. The
actual update rate may be limited by the available bandwidth of your
Ethernet network.
For each AN-X, you can define up to 10 blocks of data to be consumed
from the data produced by other AN-X modules. The consumed data is
then written to the PROFIBUS input data for slaves on the consuming
AN-X.
Each consume block has an associated timeout which can range from 5
to 16383 ms. If the consume block is not updated within the timeout
period, AN-X logs a timeout event in the bridging log.
You configure all AN-X modules on the Ethernet network with a single
configuration file, since consume blocks on each AN-X must resolve tag
name references to extract data produced by the other AN-X modules.
AN-X to AN-X communication can be used to pass data from one
PROFIBUS network to another using two AN-X-PBSLV modules or to
pass data from a PROFIBUS network to a dissimilar network using an
AN-X module for the other network.
There is no limit on the number of AN-X modules that can consume the
data that an AN-X produces.
Configuration File Format
The configuration file consists of several sections
• configuration ID
• module_ip, identified each AN-X being configured
• produce, defines produced data for that AN-X
• up to 10 produce blocks
• consume, defines consumed data for that AN-X
•
up to 10 consume blocks
