Preliminary Checks
1) Check "POWER LED". If this is OFF, please see section 9.2.
2) Check power supply for special function blocks and extension I/O units/blocks.
If this can not be supplied, 32DP-IF will not operate correctly.
3) Check that the slave addresses are the same at the 32DP-IF and in the DP-master
configuration. If the slave addresses are not the same in the 32DP-IF and in the DP-master,
change these addresses to match in both modules.
4) Check that the parameter data of 32DP-IF are set correctly in the DP-master.
If the parameter data of the 32DP-IF are not set correctly in the DP-master, communication
over the Profibus-DP network may be affected.
5) Check whether the network wiring and/or the cables for the extension blocks/units are
properly connected to the 32DP-IF.
6) Check that the system configuration rules have not been exceeded, i.e. the number of
special function blocks does not exceed 8 and control I/O of 32DP-IF is 256 or less.
