IM151-2 (Redownloading)

th0ny_15

is it true that whenever you disconnect IM from ET200iS..it will erase the configuration
Please help me about the procedure of downloading the configuration using Simatic PDM...i find it very different..

All current parameters and identification data of the ET 200iS are stored in an internal flash memory on the IM 151-2.
After replacing a module, IM 151-2automatically transfers the current parameters and identification data to the new module. This function is always active on the ET 200iS and cannot be influenced by the user.
– The current parameters and identification data are retained on the IM 151-2 even if the power supply for the ET 200iS fails.
– The default parameters of an electronics module are overwritten.
Note
The flash memory (parameters and identification data) of the IM 151-2 is erased if you change the PROFIBUS address and turn on the power supply for the ET 200iS at the power supply module.

As for the correct configuration procedure, you may find the following two links helpful:

Configuring an ET 200iS requires Hardware Configuration and SIMATIC PDM

I hope this helps and perhaps others can answer the "is it true that whenever you disconnect IM from ET200iS..it will erase the configuration" question with more certainty.
