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

LOGO! 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 LOGO! basic module as well as by the two digital alarm bs of the LOGO! CMR. The values in the LOGO! basic module can be directly influenced by receiving a text message.

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

LOGO! CMR determines the current b of the module based on the GPS signal received by the GPS antenna. In addition, LOGO! 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.

Product version:

• LOGO! CMR2020 for use in GSM/GPRS mobile wireless networks
• LOGO! CMR2040 for use in in LTE mobile wireless networks

Warning! The country-specific mobile network approvals must be observed:
