Limit value
• Byte counter
The following limit values can be set for two graduated report
messages.
Example:
▫ If a volume tariff of 10 MB/month was agreed with the mobile
service provider, with byte counter1 = 5 MB, a report message is
issued when half of this volume has been used, and with byte
counter2 = 8 MB again at 80 %. The setting is made in the menu
"Messages", see Section 4.6 Alarm Message.
• Online time
Due to technical reasons, the counter can only provide a rough
overview (guide value) of the actually used volume.
Example:
▫ Necessary repetitions when sending data which cannot be
protocolled by the IE-GPRS-I/O
▫ Different protocol overheads when sending
Counter
• Current counts
The displayed values apply with reservation and serve only as
guide values to provide an overview.
No guarantee can be given for the correctness of the above-
mentioned counter values, as the invoicing procedures of the
individual providers may differ.
The invoices of the provider are binding.
