edit the GSM/SMS parameters, double click on the GSM/SMS icon to open the Short Message
Service dialog box in AL-PCS/WIN-E. When two or more Function Blocks are trying to send a
message at the same time, the one to connect first will send its SMS message or attempt to
send its message three times. The other GSM/SMS FB(s) will be placed in "Wait" status. All
the FBs will send their messages in turn.
