Configuration (WBM)
5.13 Monitoring
You configure symbolic names as placeholders for the value to be written.
● Name
Name of the constant
● Value
Value to be written that replaces the name of the constant on receipt.
Example 1
● The name of the constant is: OFF
The name of the constant is transferred in the SMS text instead of the actual value.
● The configured value of the constant is: 0
● The SMS text is as follows: <Password>;LOGO=VM125,OFF,BYTE
When it receives an SMS message with the text "<Password>;LOGO=VM125,OFF,BYTE",
the CMR first checks the configured password.
Then according to the configuration in the table the CMR translates remaining text into
"LOGO=VM125,0,BYTE" and writes this to the variable memory of the BM.
Example 2
In this example instead of the address in the variable memory a configured signal is used, for
more information, see section Signals (Page 113).
● The name of the constant is: OFF
The name of the constant is transferred in the SMS text instead of the actual value.
● The configured value of the constant is: 0
● The signal "Light" is configured as VM125,BYTE
● The SMS text is as follows: <Password>;LOGO=Light,OFF
Please note: When using a configured signal, you must not send the data type (here:
BYTE) in the SMS text.
When it receives an SMS message with the text "<Password>;LOGO=Light,OFF", the CMR
first checks the configured password.
Then according to the configuration of the constant and the signal the CMR translates the
remaining text into "LOGO=VM125,0,BYTE" and writes this to the variable memory of the
BM.
