Hi
I have programmed a dt80m and I have various alarms which when activated are to send out an sms to 3 different numbers. within the output of alarm I have added 3 separate sms one for each mobile number as the sms output has provision for only one number. however when the alarm becomes true the dt80m attempts to send the 3 sms alerts but generally will get one out1 or 2 and sometime none as an error appears on the display of the dt80m stating data lost.

can you advise why this is happening is it that the 3 sms alerts are jamming the modem. can you advise the best solution to overcome this.
the modem once the data lost appears shuts down the modem and then tries once again but no resolution comes.
I have set the modem power to always on valid sim is inserted etc.

Thanks,
Stephen

Hi stephen,

You should set the logger to send an SMS once at a time.
Example:

RA1M
IF(...){99CV=0;GB} 'alarm condition

RB15S HB
IF(99CV==0){send 1st SMS}
IF(99CV==1){send 2nd SMS}
IF(99CV==2){send 3rd SMS;HB}
99CV=99CV+1

Hi Rudy,

Thank you for your reply. The method seems a little complex in that i have 12 different alarms which at present are programmed in dex with alarm outside range 10 to 24 sms 3 contacts. also these alarm values can vary from time to time and the end user wishes to be able to change the values within dex as he requires as he is not familiar with the datataker loggers so i want to keep it as simple as possible.

Therefore i can only have one alarm for each input sensor so the client simply changes one alarm as requires without having to change a number of values.
any ideas how to achieve this other than code programming.

Stephen.

Hi Stephen,

It will be difficult to send SMS one by one using dEX.
Could you send me your program for review?
I might be able to create something in dEX.

Hi Rudy,
please find attached program as completed in dex.

Hi Stephen,

Can you please send you dEX configuration file to the support email address?
Then we can load it up and test your configuration.

Cheers

Roger
