Process data

In the PS2001-xxxx-1001 power supplies, the process data is divided into the categories:

• "PSU Inputs"
  The process data Warning, Error, DC-OK, Output voltage (32-bit) and Output current (32-bit) are summarized under "PSU Inputs".
• "PSU Outputs"
  The "PSU Outputs" contain the values Disable output.
• "PSU Synchron info data"
  In addition, certain additional diagnostic information can be transmitted in the "PSU Synchron info data" category via the freely configurable information data info data 1 and info data 2.

There are three process data settings "Predefined PDO Assignments" to select from (see chapter "Switching the process data"):

• "Standard":
  Only the "PSU Inputs" and "PSU Inputs Device" are transmitted.
• "Standard + Synchron info data":
  "PSU Inputs", "PSU Inputs Device" and "PSU Synchron info data" are transmitted.
• Standard + Outputs
  "PSU Inputs", "PSU Inputs Device" and "PSU Outputs" are transmitted.

Interpretation of Value & Status variable

The plain text display of the bit meanings of the status word is particularly helpful for commissioning, but also for linking with the PLC program.
By right-clicking on the status variable in the configuration tree (A), the structure can be opened for linking (B).
