14.1.7.1 Power Supply Modules
The group of power supply modules has one module type divided into four
submodule types.

Power supply modules supply a provider status (IOPS) to the IO controller.
If the diagnostic data is available in the process image of the inputs, the power
supply modules receive the consumer status (IOCS) from the IO controller as
process qualifiers for the diagnostic data.

Parameters of the I/O Modules
The following subchapters list the individual attribute values and descriptions for
parameterization of the various I/O modules. The default attribute values are
highlighted in "bold".
14.2.1
Digital Input Modules (DI)
All digital input modules that do not supply any diagnostic information do not
receive a parameter data set from the IO controller.
However, digital input modules with diagnostics capability receive a parameter
data set in the form of a record write request to the data set number or index
0x4000 or 16384.
This data set receives the following attributes channel-by-channel.
