0000h No error has occurred.
8090h You have not configured a module for the logical base address that you have specified, or you have
ignored the restrictions that apply to the length of the consistent data.

under LADDR.

14.1.13 SFC 15 - DPWR_DAT - Write consistent data
The SFC 15 DPWR_DAT (write consistent data to a DP-norm slave) writes consistent
data that is located in parameter RECORD to the DP-norm slave. The length of the con-
sistent data must be three or more than four bytes, while the maximum length is 128Byte.
Please refer to the manual of your specific CPU for details. Data is transferred synchro-
nously, i.e. the write process is completed when the SFC has terminated. The length of
the respective source area must be the same as the length that you have configured for
the selected module.
If the module consists of a DP-norm slave of modular construction, then you can only
access a single module of the DP-slave.
The SFC 15 is used because a transfer command accessing the periphery or the process
image of the outputs can write a maximum of four contiguous bytes.
Consistent data
Consistent data is data, where the contents belongs to the same category and that may
not be separated. For instance, it is important that data returned by analog modules is
always processed consistently, i.e. the value returned by analog modules must not be
modified incorrectly when it is read at two different times.
