Modifying Hardware configuration withoutturning the CPU to Stop

Hello everyone,

I have a process with a S7-1500 (alone) and a ET200 (ref:IM 155-5 PN ST) containing various DI DO AI AO cards.

I need to modify the settings of some channels from the AQ cards (i need to change from 0-10V to 4-20mA).

I'm afraid that when i load the modification, the PLC turns to STOP mode.

My problem is that i can't stop the process.

Can you tell me if it's possible to load these modifications without the PLC turns to stop mode?

Regards

Can you tell me if 

hi,

I´m afraid to say that you have to stop it to load HW-config.

But maybe I´m wrong. 

To investigate better it would be helpful to know what exact module you want to change.

The more we know the more we can help.

Hello, thank you for your answer:

Here is my configuration:

 S7-1500 with no additionnal cards

 ET200 with  2*DI32 - 1*DQ32 - 2*AI8 (AI 8xU/I/RTD/TC ST) - 1*AQ4 (AQ 4xU/I ST)

Both are communicating in Profinet,

I just would like to change settings from 0-10V to 4-20mA on the channels from the AQ4

And also add the Quality information on AI8

Regards

hi,

when someone asks for a exact module, he normally wants to know the order-no./MLFB

But I don´t need it anymore, because of there is only one AQ4-module in ET200MP-Series. 

All parameters are changeable in Run, over WRREC, using data record 128. The parameters set in STEP 7 are not changed in the CPU, which means that the parameters set in STEP 7 will be valid again after a restart.

you can read this information in the manual of the module:

SIMATIC ET 200MP Manual Collection  page 2670 and 2496.

AI module parameters are changable too

hope this helps,

regards,

Thank you for your answer, the manual is very helpfull.

So if i understand, i have to use the WR REC Block with following ping assignment :

Req : writing request

LADDR : ID from my AQ

RECNUM : 128

RECORD : %Lxxx with programmed corresponding parameters

RET_VAL : #RET_VAL

BUSY : #BUSY

Last question, i don't understand what to enter in bytes 0 and 1 from the header informations, are they the same as in the manual p2466?

I will test is this afternoon

 hi,

seems to be right. 

p2466? please check this page, I guess you mean an other, but I don´t know which.

regards,

I have another question about that block,

Do you know if it works when using PLCSIM?

I would like to check if it's ok before going on the field
