CPU just stooped with no error announcment

Wizard

Hello,

6ES7195-7HB00-0XA0 is an active busmodule for two I/O modules (width 40mm)

It is not voor the IM153-2 module.

You need 6ES7195-7HD10-0XA0 to connect both IM153-2 modules.

Best regards,

 Hello Everybody.
I´m having trouble with a CPU 315-2 PN/DP (6ES7 315-2EH14-0AB0) and installing additional remote modules to it, IM 153-1 (6ES7 153-1AA03-0XB0).
The actual conditions that I have been working with, for years in the factory is with one CPU 315-2 PN/DP and six  IM 153-1 slaves plus one HMI Magelis as slave too. So in resume, I have 7 slaves connected to the CPU 315-2 PN/DP. So in this conditions I do not have any trouble.
Recently, we are adding various signals to the same system for additional functions to be automated. In this try, we added two more IM 153-1 slaves. So in sum, we now have a total of 9 slaves. We already made the hardware configuration and connected these other two slaves to the network. It apperently has no trouble, we dont have any software or bus fault led indications in the CPU. We have not write any code yet to the new remotes.
In the beggining there was no trouble for about 24 hrs, but suddently the CPU just stooped with no error announcment. And that is happening every 24 hrs (more o less). We had to disconect this two slaves in order to solve this problem because were having trouble with production stops.
I wonder if the if the problem is that we are connecting to much slaves that the CPU cannot support.
I read the specifications of the CPU and according to it I have a number of 124 DP slaves support. But it also says: Number of DP slaves that can be simultaneously  activated/deactivated, max. 8; wich I dont understand.
Does this last spec has something to do with my problem?

Any tips?

Thank you all.

Regards.
