In the System SLIO there is the possibility to place up to 64 modules in on line. By means
of the line extension you can divide this line into several lines. Here you have to place a
line extension master at each end of a line and the subsequent line has to start with a line
extension slave. Master and slave are to be connected via a special connecting cable. In
this way, you can divide a line on up to 5 lines. For each line extension the maximum
number of pluggable modules at the System SLIO bus is decreased by 1. To use the line
extension no special configuration is required.
