Hello, I have a LOGO! 8 controlling a device in a remote location, and I would like to be able to get notified if something is wrong (by SMS/email) and possibly also monitor the LOGO remotely. I am currently looking at the CMR2040, which obviously appears to be made for this purpose. One of the things I would also like to get notified, is if there is a power outage, so I wonder if anyone knows where to find a 24V power supply with some kind of backup (supercapacitor or small battery) that can keep the CMR running long enough for it to send an SMS. My idea is to connect a N/O contact of a 230V coil relay at one of its digital inputs, so that when the 230V mains disappears the relay opens, the input of the CRM goes to 0 and an SMS is sent. I am guessing a few seconds should be enough, but maybe someone has more experience about the time it takes for the CMR to process its input and send something. The main alternative I am looking beside the CMR, is the Advantech ICR 3211B which has this supercapacitor and last-gasp SMS feature built-in. https://advdownload.advantech.com/productfile/PIS/ICR-3211B/file/DataSheet_A4_ICR-3211B_02062020_email20200603113148.pdf I feel it is superiour to the CMR in several ways, for a very similar price. E.g. you can configure OpenVPN as a client, not only as a server as in the CMR and thus removing the need for a public IP address (which I really don't like); and you can configure and run your own applications (e.g. Node-red, MQTT, etc). The CMR obviously has a native integration with the LOGO! so getting the LOGO! to work together with the Advantech would definitely need more work, and won't be as seamless. On the other hand switching to the LOGO! 8.3 and using its cloud connectivity, would make the CMR just good enough for my use case (as I would just use it for SMS and internet connection, no VPN or advanced stuff, so a private IP would be enough). Any tips are much appreciated, thank you! jonian AttachmentDataSheet_A4_ICR-3211B_02062020_email20200603113148.pdf (877 Downloads) |
