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.
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.
If, for example, a PI-SMS message requested using SMS was sent incompletely, repeat your
request SMS message.
