11.10 Autocall Function
The auto call function enables the data logger
COMBILOG 1022 to send messages automatically via modem
or as SMS. The conditions, at which messages should be
send, can be defined by the configuration program. Following
options are available:
Dial Conditions:
• On System Error: The data logger has detected an
internal hardware error
• On Range Error: The measuring range of a variable
has been exceeded.
• On Alarm: One of up to 4 definable threshold values
has been exceeded.
In case of using a telephone modem up to 3 telephone num-
bers can be defined, being dialled one after another in case of
a dial condition is fulfilled.
After establishing a connection the data logger sends a status
message, and the remote subscriber can communicate with the
data logger, e.g. to read out the data memory. The data logger
will hang up the modem, if there is no further communication
for more than 30 seconds.
