The CMR supports the following basic functions:
1. Web user interface (WBM) for the configuration; protected with login and password query.
2. Cyclic reading of the process image from the BM.
3. From incoming events, events coming from the process or internal, suitable output
reactions configured using WBM are generated: For example sending an alarm SMS
message.
4. Event configurations and reactions, for example trigger an alarm SMS message if a value
changes in the process image.
The process image consists of the following elements that you can use for an event or
alarm configuration:
– Digital and analog inputs
– Digital and analog outputs
– Digital and analog bit memory
– Shift register
– Operator keys
– Function keys
5. Access to variable memory (VM)
Via the variables memory, you have access to the current values of function blocks, for
example counter function blocks.
6. Time-of-day synchronization
– NTP
– GPS
– Mobile wireless network (depending on the mobile wireless provider)
7. Forwarding the time of day to the BM
8. GPS position
– Querying position by SMS
– Forwarding position to the BM
9. The two inputs/outputs of the CMR can be configured using the WBM and read or set
using SMS messages.
