Hello,

I'm trying to get a CP 1243-7 to send alarm SMS messages to mobile devices.

I've followed the"Signaling and Switching via SMS with S7-1200 and CP 1242-7 GPRS V2"guide which states the user blocks can also be used in a 1243-7 device too.

The problem is that when I use CP 1242-7 all work great but with CP 1243-7, FB3 - BroadcastSms has error state 16#0001_809A

It's state of TSEND_C and means:

The CONNECT parameter points to a field that does not correspond to the length of the connection description.

But why with CP 1242-7 everything is ok and CP 1243-7 is the problem?

Any idea?

Thank you.
