Number of connected modules Without repeater: Max. 32 stations for each segment.
With repeater: Total of Max. 126 stations.
PROFIBUS network must have all the stations joining the network registered before operating.
Refer to the master unit, configuration tool manual to find out how to register.
There are GSD files with the data for each station that allows PROFIBUS to be configured
easily. GSD file is defined for the communication function of a device, allowing you to
configure a PROFIBUS network with stations manufactured by various manufacturers.
GSD files for PROFIBUS devices that conform to PROFIBUS standards can be downloaded
