Operating Instructions, 10/2016, C79000-G8976-C356-03
The CMR checks the text of the SMS message for keywords or with write SMS commands
first for the password specified in the configuration:
●
If the SMS message does not contain any keywords or no or an incorrect password an
entry is made in the diagnostics buffer.
–
If the SMS message comes from an authorized phone number, a reply SMS message
is always sent.
–
Exception: If the SMS message comes from an unauthorized phone number or “Allow
receipt of SMS messages" is deactivated, the SMS message is discarded.
Password configuration for SMS messages with write access
Note
No semicolon in the password
•
The password must not contain a semicolon ";".
•
The password must be separated from the keyword with a semicolon.
SMS messages with write access can be preceded by a password: You configure this
password using the WBM.
The password counts as the authorization of the user and prevents manipulation of
LOGO! BM or LOGO! CMR values.
Replying to SMS messages
SMS messages from authorized users can be replied to by the CMR (configurable). With
write access, this reply consists of a positive or negative acknowledgement of the write
procedure.
Note
Preventing an SMS message loop with linked CMRs
To avoid several CMRs connected by mobile wireless forming an SMS loop,
acknowledgement frames are received but are not replied to.
The number of SMS jobs/time is limited
The CMR stores a limited number of SMS send jobs in a job queue.
Sending an SMS message may take several seconds due to the delayed transfer in the
mobile wireless network.
Follow the points below to make sure that all SMS messages are sent within the required
time:
●
Adapt the length of the interval for large amounts of data to be sent cyclically, e.g. PI-
SMS messages (monitor SMS) accordingly.
●
Make sure that there is enough time between different actions sending PI-SMS
messages.
