Parameter data records
A.3 Parameter assignment and structure of the parameter data record for pulse width modulation operating
mode
Codes for time period of the pulse width modulation
The following table contains the codes for the time period of the pulse width modulation of
the digital output module. You must enter these codes in bytes x+6 and x+7 of the channel
parameter block of data record 128 (see previous figure).

Errors when transferring the data record
The module always checks all the values of the transferred data record. Only if all the values
were transferred without errors does the module take over the values from the data record.
In case of errors, the WRREC instruction for writing data records returns corresponding error
codes in the STATUS parameter, see also the description of the "STATUS" parameter in the
STEP 7 online help.
The following table shows the module-specific error codes and their meaning for data record
128. The error codes are supported starting from firmware version V2.0.0.
