Application examples
5.2 Mobile wireless communication with LOGO! BM
If the CMR is connected to the BM, and if you have a mobile wireless antenna connected,
you can use all the functions available in operation without a connected BM. In addition to
this, access to the LOGO! BM is expanded:
● Sending an SMS message due to an event in the connected BM.
● Receiving an SMS message:
– Triggering an action in the connected BM.
– Sending status information via the BM using SMS messages.
Configuration using the WBM also includes access to the components of the BM.
Requirements
1. Installation, connecting up, commissioning (Page 25) completed.
2. Antenna for mobile wireless reception connected.
Procedure
To set up access via the mobile wireless network and to establish a connection to the BM,
follow the steps below:
1. First establish a configuration connection between the CMR and a connected PC. To do
this, use an Ethernet patch cable.
See Establishing a connection to the CMR (Page 49)
2. Configure the mobile wireless connection:
See Mobile wireless settings (Page 77)
3. Configure the device using the WBM.
4. When configuration is completed, disconnect the CMR from the PC.
Note
Using a switch
When using a switch, e.g. LOGO! CSM, do not disconnect the connections: BM, CMR
and PC can be operated at the same time.
5. If you do not use a switch: Connect the CMR to the BM.
