[S7-400] Object Properties - The data is read-only

[Kalis]

Hi,
I'm using STEP7 v5.6 with CPU 414-3 PN/DP,
When I'm trying to open Object Properties of the CPU I get "The data is read-only"
The HW Config and Ethernet are configured,
I'm not sure if that is causing it but - the batteries are missing on the PS-407 10A (BAF LED is red, BATT1F LED is yellow), and on the CPU EXTF LED is red.


I also tried to reset the memory, but the "read-only" error still exists.


Please help me fix this problem.


Thanks.

In short
Hello,

regarding to your picture, this is correct. If you open the CPU properties from the SIMATIC Manager, you can only read.

Open the hwconfig (hardware configuration) and double click on the CPU 315. The properties dialog will open and you can change the data.
