SIEMENS LOGO! CMR (wireless communication)

LOGO! CMR in combination with the LOGO! logic module is a cost-efficient communication system suitable for monitoring and controlling distributed plants and systems via text message or email.

LOGO! CMR can send text messages or emails to predefined mobile network numbers as well as receive text messages from predefined mobile network numbers.

Sending a text message/email can be initiated by events in the LOGO! basic module as well as by the two digital alarm inputs of the LOGO! CMR. The values in the LOGO! logic module can be directly influenced by receiving a text message.

The LOGO! CMR offers comfortable Web Based Management commissioning and diagnostics via local and/or remote access.

The two digital outputs can also be switched remotely by incoming text messages/emails.

LOGO! CMR determines the current position of the module based on the GPS signal received by the GPS antenna. In addition, the LOGO! 8 logic module can be time-synchronized by means of the time included in the GPS signal. Determination of time by means of an NTP server or from the data of the mobile network provider offers more options for synchronization of the LOGO! BM with the current time of day.

Benefits

  • Cost-efficient alarm signaling system – Low investment and operating outlay for the monitoring and control of small facilities via text message and/or email
  • Reduction of travel/maintenance costs thanks to remote access via OpenVPN and HTTP for configuring the LOGO! CMR or LOGO! 8 logic module
  • Easy-to-use thanks to intuitive text messaging syntax with alias text messaging function or assignment and use of symbolic names
  • Simple configuration process via Web Based Management without the need for special knowledge of radio communications
  • Internationally deployable thanks to communication via GSM, UMTS, and LTE networks
  • Time synchronization of the LOGO! 8 logic module using the time determined from the GPS signal, an NTP server or the time from the mobile radio provider
  • Harmonizes with LOGO! 8 series with regard to functioning, design and structure
  • Quick assembly due to DIN rail mounting

Application

In industrial environments
  • Easy remote diagnostics and remote control tasks in LOGO! applications in plants and machinery, e.g. gate controllers, ventilation systems, industrial water pumps, automatic feeders in agriculture
  • Easy building automation including building services, e.g. for HVAC (heating, ventilation and air conditioning), pump control
  • Remote control and monitoring, e.g. of fill level, pressure, temperature, flow rate, valve control in water/wastewater
  • Position monitoring in logistics, e.g. for vehicles, refrigerated trucks, containers
  • Easy metering and energy management systems in distributed buildings that are controlled with LOGO!
  • Construction of systems for monitoring and controlling of simple telecontrol stations
  • Remote connection of distributed, local controllers by means of LOGO!
