7.3 Slot - index tables
7.3.1 Indirect slot addressing
If your PROFIBUS master in the DP-V1 service is not able to write/read arbitrary slot addresses (e.g.
in the Siemens S7 environment), it is necessary to map the desired destination slot with the aid of
indirect slot addressing. See chapter 7.1 Indirect slot addressing, e.g. for Siemens S7 projects.
