Operation of the module behind a PROFIBUS DP interface module
If the module is operated behind a PROFIBUS DP interface module, the parameter data
records 0 and 1 are not read back. You get the diagnostics data records 0 and 1 for the read
back parameter data records 0 and 1. You can find more information in the Interrupts section
of the PROFIBUS DP interface module device manual on the Internet
(http://support.automation.siemens.com/WW/view/en/78324181).
