1) Check “POWER LED”. If this is OFF, please see section 8.2.

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 configu-

ration. 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 parameters of 32DP-IF are set correctly in the DP-master. 

If the parameters 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 prop-

erly connected to the 32DP-IF.

6) Check that the system configuration rules have not been exceeded, i.e. the number of spe-

cial function blocks does not exceed 8 and control I/O of 32DP-IF is 256 or less.

7) Put RUN/STOP switch on the 32DP-IF into RUN.
