CMR2040 개요
A cellular communication module is a hardware accessory that adds wireless wide-area-network (WWAN) connectivity to an industrial controller that natively has only local I/O or Ethernet. In the PLC hierarchy, modules like the CMR2040 sit alongside the CPU and I/O expansion modules and are classified as PLC communication modules (PLC add-ons). They enable remote telemetry, alarm routing, and cloud/SCADA bridging that would otherwise require a separate gateway PC or router. The CMR2040 is specifically engineered for the LOGO! 8 (0BA8) family, and snaps onto the controller's left-side expansion bus without external wiring.
Key features include SMS command handling for status queries and setpoint writes, real-time clock time synchronization and forwarding to the connected LOGO!, GPS-based position detection for mobile or remote assets, and read/write access to LOGO! variables from any subscribed mobile phone. Configuration and diagnostics are performed through a built-in web server reached over the Ethernet port. Two digital inputs and two digital outputs are exposed for direct local wiring of sensors and actuators, allowing the CMR2040 to function as a small remote terminal unit (RTU) even when the host LOGO! is offline.
Typical applications include remote pump-station monitoring, lift-station SCADA reporting, mobile equipment telemetry on trucks and generators, agricultural irrigation control, and alarm routing from unmanned sites. The integrated GPS makes the module well suited to fleet or container tracking where the host LOGO! is logging operational parameters that need to be geo-tagged.
When deploying the CMR2040, verify that the national LTE bands supported by the module match the operator in the target country before purchase, and ensure the SIM card is provisioned for SMS and packet data. The module is intended for indoor cabinet mounting within the LOGO! 8 system; an external antenna is required for cellular and GPS signals.

일반적인 애플리케이션
CMR2040 적합 용도: 6 애플리케이션s: Remote Pump Station Monitoring, Lift Station SCADA Reporting, Mobile Equipment Telemetry, Agricultural Irrigation Control, Unmanned Site Alarm Routing, Container and Asset Tracking.
Remote Pump Station Monitoring
The Siemens CMR2040 provides unattended pump-station telemetry over LTE for utilities operating widely distributed assets. With 2 digital inputs it can monitor float switches, flow sensors, and intrusion contacts, while the 2 digital outputs can start/stop a backup pump or open a discharge valve. SMS dispatch alerts operators to high-level alarms, and read/write access to LOGO! variables lets them remotely change setpoints (pump start level, run hours) from a mobile phone - eliminating the need for a SCADA PC at every site.
추천
Lift Station SCADA Reporting
Wastewater lift stations use the CMR2040 to push level, runtime, and fault data to a central SCADA system over LTE, avoiding the recurring cost of dedicated radio or cellular SCADA gateways. The module's email dispatch function sends batched daily reports, while SMS provides instant alarms on high-level and pump-failure conditions. The integrated GPS lets the utility map and verify the location of every lift station in its network, simplifying regulatory reporting and field-crew dispatch.
추천
Mobile Equipment Telemetry
Mobile and relocatable equipment such as truck-mounted generators, well-service rigs, and rental air compressors benefits from the CMR2040's combined LTE + GPS connectivity. The host LOGO! 8 logs operational parameters (engine hours, fuel level, fault codes) and the CMR2040 publishes them via SMS and email to the operations centre. GPS position detection allows fleet managers to track equipment location in real time and recover stolen or misplaced assets.
추천
Agricultural Irrigation Control
The CMR2040 enables remote start/stop and status reporting of irrigation pumps, valves, and filter stations across large farms where running control cables is impractical. Operators send an SMS command to open a sector valve, and the CMR2040 toggles one of its 2 digital outputs and replies with confirmation. Time synchronization from the cellular network keeps irrigation schedules accurate even after long power-off periods, eliminating clock-drift issues common in standalone controllers.
추천
Unmanned Site Alarm Routing
Telecom base stations, electrical substations, and remote warehouses use the CMR2040 to forward intrusion, fire, and equipment alarms to security staff via SMS and email. The 2 digital inputs accept dry contacts from PIR sensors, smoke detectors, and door switches, while the 2 digital outputs can trigger local sirens or strobes. Configuration through the built-in web interface lets installers define alarm recipients and escalation rules without custom programming tools.
추천
Container and Asset Tracking
Shipping containers, portable substation skids, and construction-site tool containers use the CMR2040 plus LOGO! 8 combination as a low-power tracking and telemetry node. The integrated GPS reports position at configurable intervals, while the 2 digital inputs can monitor door-open events and temperature alarms. Operators query the LOGO! variables by SMS to read internal state, or receive automatic SMS/email pings when the container moves outside a defined geo-fence.

설계 노트
The CMR2040 is approved for specific national LTE bands; ordering the module for the wrong country is a common procurement pitfall because the marketing name 'CMR2040' is the same worldwide but the internal radio differs by MLFB suffix. Confirm the destination country's LTE band plan and select the appropriate Siemens national variant before purchase. Using a CMR2040 variant outside its approved country can violate radio regulations and void the warranty.
The CMR2040 requires external cellular and GPS antennas connected via SMA connectors on the top of the module; antennas are not included in the box. Mount the antennas outside any metallic cabinet using coax rated for the LTE band in use, and provide adequate separation (typically 200 mm minimum) between the cellular and GPS antennas to prevent receiver desensitization. Antenna gain and cable loss directly affect both data throughput and GPS fix time.
Power the CMR2040 from the LOGO! Power module on the expansion bus; do not back-feed 24 V through the local I/O terminals. The module draws additional current during LTE transmit bursts - size the LOGO! Power supply with at least 25 percent margin above the steady-state CMR2040 draw, and use a low-impedance 24 V source so transmit bursts do not cause the LOGO! CPU to brown-out. A 24 V decoupling capacitor (>= 470 uF) at the CMR2040 power terminals is recommended.
The CMR2040's SIM card slot requires a SIM provisioned for SMS plus packet data on the LTE network; a data-only M2M SIM will accept the module on the network but SMS command-and-control will not work. Configure SMS routing rules and authorized phone numbers through the built-in web interface before commissioning, and lock down the web interface password - the module exposes the web UI on its Ethernet port by default.
