MAS 5: SMS receive doesn´t work - Error/Status 7

In the Micro Automation Set 5 f.e. existing text messages are picked up time controlled by the connected GSM modem.

This is done in the library subroutine "SMS_Receive".

Text messages can be deposited in different storage areas of the modem. The subroutine "SMS_Receive" has to be informed about that.

Possible storage areas:

Excerpt from TC65T AT-command-set (from chapter 13): link

"..
ME: memory storage (logic sub-division, mem1, mem2, mem3, ....)
ME1: log. division of ME
MEx: log. division of ME
SM: SIM card
MT: Sum of ME und SM

With the command AT+SSMSS a preferential storage area can be assigned manually to the modem.

With the command AT^SLMS you can be showed, how many short messages are present in which storage area.

.."

Changing the used storage areas in the component "SMS_Receive":

Depending on the modem which is used or on changed settings it can be necessary to adjust the favorite storage area in the library that should be used. This is done each with the abbreviations “ME, SM, MT, MEx”.

In order to do so, open in the library "set5_s7-200-library.mwl" the component "SMS_Revceive". Navigate to the network 9 “Command 3”.

The block "STR_FIND" shows in which storage area it has to be looked for text messages. Fill in here "ME", "SM", "MT" or ME specified by MEx. Save and load the program to the control.

Starting from version 2.0 of the library components (available since approx. March 2008) it is regardless which storage area the favorite is. So the preceding article is decrepit apart from the functional information.
