4. The total lengths of input and output mapping for all configured I/O modules are both 244
bytes at most and the total length of all configured I/O module parameters is maximum
244 bytes. Therefore, different input and output mapping lengths of different modules and
parameter lengths will decide the number of the configured I/O modules.
14.5 Transmission Distance and Baud Rate
The PROFIBUS DP baud rate ranges from 9.6Kbps to 12Mbps. The transmission distance depends
on the baud rate. The range of the transmission distance is between 100m to 1,200m.
The baud rate and the corresponding transmission distance that AHRTU-PFBS-5A supports are
shown in the following table.

14.6 GSD File
The GSD file, a text file, is used to recognize the PROFIBUS device (master or slave). GSD file
includes all necessary data information for configuration of one slave in the standard PROFIBUS DP
master. The GSD file usually contains the supplier’s information, supported transmission speed and
available I/O information. Before using AHRTU-PFBS-5A, import its GSD file to the configuration
software of the PROFIBUS DP master. After the GSD file is imported, AHRTU-PFBS-5A and other
configuration options will show up in the master configuration software. The GSD file of
AHRTU-PFBS-5A can be downloaded from the following Delta website.
