Posted 1 Dec 2009 Being that Twido is a Modicon product, you might get more responses in the Modicon forum. But you would not need Modbus for ASCII communications. I recommend if you are going to outsource this programming that you find an integrator who is familiar with the Twido PLC, and they should understand how to make it send a string of text. But please keep in mind there is much more to sending an email or SMS message. Such as access to the Internet. For that, you would want an Ethernet module, not serial.

Posted 1 Dec 2009 (edited) I am not sure the Twido has the ability to do all of that, speficially the e-mail. I would place a PC there, does not have to be high end, running an OPC server and then you can either create your ownOPC Cleint with and E-mail applicaiton in it or get a product like Win911(http://www.specterinstruments.com) which is designed to do just that. Win911 is an OPC Cleint and it can be configured to do allarm notifification upon multiple conditions. Edited 1 Dec 2009 by Tech Fred Share this post Link to post Share on other sites
Posted 1 Dec 2009 Moderator note: I merged the two topics and placed one version here in Modicon as suggested. Share this post Link to post Share on other sites
Posted 1 Dec 2009 Hi Keith, did u see at Schneider Electric website?? If you really are canadian have a look here and find and download this "Twido S1013 vA MODEM RTC & GSM" If it is not useful search for other FAQ or manual in any Schneider website. You'll find everithing you need. Share this post Link to post Share on other sites

Posted 4 Dec 2009 I did this job once using SMS messages. Used the Twido serial port configured as ASCII, connected to a SR2MOD03 (Schneider Electric reference for a GSM module). As someone said, there is a guide at Schneider Electric website to help doing the job. It's not so easy, but can be made. You will also need a GSM chip from some cellular phone operator. With extra research, I think that you can send emails using the GSM chip (if you have this service) and using the modem full manual. I know that twido does not offer the email service directly, an other solution would be a PC and a OPC Server and maybe extra software. An other option would be using a Zelio Logic with the SR2MOD02. Zelio has every thing prepared for sending SMS messages, you just have to configure it, it's much easier, and the only thing to do is send a digital signal from twido to the zelio logic. I attached the modem user guide for you. sr2mod0x_se_000_en.pdf Share this post Link to post Share on other sites
