Siemens SIMATIC ET 200iSP

• IM 152-1DP: After loading the ET 200iSP, all current parameters and identi󹪝cation and
maintenance data are stored in the interface module. After replacing an electronic module,
the interface module automatically transfers the current parameters and identi󹪝cation and
maintenance data to the new module. This function is always activated in the ET 200iSP and
cannot be parameterized.
– The current parameters and identi󹪝cation and maintenance data remain safely stored in
the interface module even after a failure of the ET 200iSP supply voltage.
– The default parameters of an electronic module are overwritten.

Note
If you reduce an existing con󹪝guration and then extend it again, you should erase the
󹪞ash memory before the extension.
The 󹪞ash memory (parameters and identi󹪝cation and maintenance data) of the IM
152-1DP is erased if you set the PROFIBUS address to "0" and then switch the supply
voltage of the ET 200iSP o󹪜 and on at the PS power supply.
• IM 152-1PN does not store current parameters, identi󹪝cation and maintenance data. The
parameters are processed at every connection to the IO controller. The identi󹪝cation and
maintenance data are not updated automatically and the user must take care to make the
correct setting of these values. It is no longer necessary to perform a reset to factory settings
for a con󹪝guration extension.
