- Logo! CMR2020 communications module enables access to Logo! 8 logic module using SMS
- Time-of-day synchronisation of Logo! 8 based on information from GPS, NTP server or mobile phone provider
- Positioning data determined by GPS
Users of the Logo! 8 logic module from Siemens Industry can now control it or receive status data and alarms via text messages to their mobile phones, following the launch of the Logo! CMR2020 communications module.
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.
Joanne Banks, Product Manager at Siemens Industry, commented: “The Logo! CMR2020 can be quickly and easily connected to the basic Logo! module via an Industrial Ethernet interface. As well as programming commands, the user saves a list of mobile phone numbers that are authorised to control and receive process value and diagnostics data, as well as alarms. The text messages are password-protected to ensure protection. Using the two inputs and two outputs, Logo! CMR2020 can also be used for simple control tasks as a stand-alone unit.”
