Configuring

Requirements
Via PROFINET IO:
● Configuration software, for example STEP 7 Professional as of V13
● IM 157-1 PN
● You have assigned the interface module to an IO controller in STEP 7
Via PROFIBUS DP:
● Configuration software, for example STEP 7 Professional as of V13
● IM 157-1 DP
● You have assigned the interface module to an DP master in STEP 7
● The parameter "Operation if preset configuration does not match actual configuration" is
activated.
The parameter "Operation if preset configuration does not match actual configuration" is
located in STEP 7 in the properties of the interface module under "Module parameters" >
"Start-up".
Note
Disabled parameter "Startup if preset configuration does not match actual configuration"
If an I/O module is missing or an incorrect or additional I/O module is plugged in and the
"Startup if preset configuration does not match actual configuration" parameter is
disabled, the ET 200AL distributed I/O system does not start up.
The diagnostic "Slot x no module" or "Slot x wrong module" is generated.
If the IM 157-1 DP interface module does not start up in this status, the RUN and ERROR
LEDs on the interface module flash red. The DIAG LEDs flash green on all I/O modules
as well.
