Hi experts, just a stupid question, but It would be great if it was possible.. 

It's possible to configure in a 1500 at design time a type for an analog input (eg 4..20 mA) and at runtime modify this configuration (eg 0..10 V)? Is not a problem if i have to restart PLC like an hardware download.

Maybe some system FC..

This question comes to me when i discover that is possibile to disable a PN node at runtime (great!).

Thanks for your time

hi dirk,

yes, its possible. Have a look in the manual of the module you want to use.

In the chapter where the parameters are described you find a not which parameter is changable in run.

SIMATIC S7-1500/ET 200MP Manual Collection

Manual 6ES7-531-7KF00-0AB0 chapter B

Parameter assignment in RUN
Instruction WRREC is used to transfer the parameters by means of data records 0 to 7 and
8. The parameters set in STEP 7 do not change in the CPU, which means the parameters
set in STEP 7 are still valid after a restart.
The parameters are only checked for plausibility by the module after the transfer to the
module.

 hope this helps,

regards,

Great, mopS04! I saw that manual many times but I've never take a look to that appendix, is really what I was looking for!

Thanks again, I'll make some test
