Posted 18 Jun 2020 Good day, Does anybody know if one can connect multiple micro 800 PLC's to each other via GSM? Share this post Link to post Share on other sites
Posted 21 Jun 2020 There was a GSM modem module available for the Micro 800 series controllers, marketed and supported by ProSoft Technologies in California. But I think its heyday of the ILX-800 was eight years ago, before the advent of many other wireless gateways and IOT protocols. What sort of GSM networks are available where these controllers are installed ? What sort of SCADA software are you using ? There may be other network gateways, especially ones the use protocols like MQTT, that are more appropriate than trying to use Short Message Service. And of course the task of "connecting multiple controllers to one another" is a little different than "connecting multiple controllers to a central control and supervisory system".
