Preliminary Checks
1) Check “POWER LED”. If this is OFF, please see section 5.2.
2) Check that the slave address is the same at the 32DP-IF and the DP-master configuration.
If the slave address is not the same in the 32DP-IF and in the DP-master, change this
address to match in both modules.
3) 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.
4) Check whether the network wiring and/or the cables for the extension blocks/units are
properly connected to the 32DP-IF.
5) 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.
6) Put RUN/STOP switch on the 32DP-IF into RUN.
