Siemens CMR Wireless Communication Module

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

CMR can send text messages to predefined mobile network numbers and it can also receive text messages from predefined mobile network numbers.

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

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

CMR determines the current position of the module based on the GPS signal received by the GPS antenna. In addition, BM can be time-synchronized by means of the time included in the GPS signal.

Determining the 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.
