CP1430 NOT SYNCHRONIZED status

[sigmadelta]

From the manual:

if you want to re-synchronize all the interfaces:
– First set the CP 1430 TF to STOP using the mode selector.
– Make sure that the correct number of SYNCHRON HDBs are triggered
on the PLC.
– Set the CP 1430 TF to RUN using the mode selector.

STOP AND START the CP in COM1430TF?

Yes, many times

Don't work too

Are the green RUN and red STOP lit on the CP?

 

[sigmadelta]

Try the following:

STOP the CPU using STEP 5
STOP the CP
RUN the CP
RUN the CPU using STEP 5

 

[sigmadelta]

Make sure the SSNR is either 0 or divisible by 4. (4,8,12...)

 

[gustavo_dias]

Are the green RUN and red STOP lit on the CP?

Yes, both

Try the following:

STOP the CPU using STEP 5
STOP the CP
RUN the CP
RUN the CPU using STEP 5

No sucesfull

Make sure the SSNR is either 0 or divisible by 4. (4,8,12...)

My SSNR is 4

Try having only the SYNCHRON blocks, and no SEND/RECEIVE code.

...and make sure FY20 is not being used somewhere else in your program (you can use cross references)

 

[gustavo_dias]

Nothing.
And I try all restart CPU/CP possible

 

[sigmadelta]

I think you must do a COLD RESTART from STEP5.

 

[gustavo_dias]

Don't work. I do cold restart in step 5 and in CPU, nothing happened

 

[sigmadelta]

I remember having a hard time for a while getting the synchronization... it was the COLD RESTART that did it in the end.

Which LEDs are lit on the CP and which LEDs are lit on the CPU?

 

[gustavo_dias]

In CPU only green LED, in CP Green and Red LED.

For COLD RESTART I try in Step 5 (C Restart) and in CPU I hold the reset switch in the RESET position and in the same time, switch the mode selector from STOP to RUN

 

[gustavo_dias]

I have a new information. I monitored my PAFE synchronous status. The error is "Interface does not exist". Do you know what's means?

 

[sigmadelta]

The only thing I can say is make double sure your SSNR in the CP1430 online matches the SYNCHRON block.
