Siemens SIMATIC ET 200iSP

• Backing up the parameters of the electronic modules:
– The parameters/data are stored in the 󹪞ash memory of the IM 152-1DP.
• Startup
– After switching on the power supply of the ET 200iSP, the IM 152-1DP distributes the
saved parameters/data to the electronic modules (e.g. substitute values for the output
modules).
– The PROFIBUS DP is then enabled and the automation system is commissioned by the DP
master.
– The substitute values (of the 󹪞ash memory) are replaced with the actual data of the IO
controller only when the ET 200iSP exchanges data with the IO controller.
