7.2 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.
Note
Follow these points in conjunction with the configuration control:
Before you can use the configuration control together with F-modules, the PROFIsafe
addresses must be assigned to the F-modules in the designated slots.
For this, each F-module must be plugged into the slot configured for it. The actual
configuration may differ from the set configuration.
