Once a SIM card has been inserted, the communications module can be accessed as a node on the mobile network. Users can configure different commands in the Logo! 8 for remote access and then trigger them by text message via the communications module. In the other direction, Logo! CMR2020 transmits diagnostics data and alarms as message texts to mobile phones previously defined as receivers.
Logo! CMR2020 has a GPS antenna connection that helps, for example, to track the current position of container freight worldwide or to monitor truck shipments. Logo! CMR2020 also enables time-of-day synchronisation of the connected logic module, based on time information provided by the mobile phone provider or NTP server, or the GPS time signals.
Logo! CMR2020 and Logo! 8 can be deployed, for example, in building control systems, such as for blinds, garage doors, lighting or garden watering systems. The Siemens components are also suitable for simple control tasks in industry, such as pump control or level monitoring.
