Hi,

I am using SMSServie to send / receive sms.
Sending sms works very well.
I have a problem with receive sms....

I did this that I cyclic call function to receive sms an I chec if any message is available.
But sometimes when I run cyclic receive sms I get error :
"No source code available for this object because it is in the compiled library 'caa behaviour model, 3.5.11.0 (caa technical workgroup)'. Do you want to browse for the original library in order to display the source code?"

And PLC achieve stop mode and fault.

Whe I turn off cyclic call receive sms function everything with PLC is ok.

What can be wrong ? My cyclic call receive function ?
It is possible receive sms for example by event ? or something similar ?

Please helps.

I solved part of my problem with SMS Service.
Problem was in sending and receiving SMS in the same time.

Now everything works good - sending,receiving and deleting sms but only about thirty minutes.
Next sms do not work. I must turnOFF and turn ON PLC to it works SMS.
I do not know what can be wrong.

I get log :
Sun Oct 13 2019 21:56:24.044584 mdmd: Signal strength below 3
Sun Oct 13 2019 21:56:24.053324 mdmd: Signal strength below 2

Sun Oct 13 2019 21:56:47.497527 mdmd: Signal strength 5 or above

Probably it is caused when Modem port timeout appear... why modem is timeout ?
I tried reinit SMS form my program but it doesn't work. I must restart my PLC.
