4 Modbus master reading
The device can be set to collect data from meters connected to its
Modbus master port. Collected data is sent to the server. Modbus
master reading settings can be given with a server application.
5 Failure Recovery
The device has no built-in backup power, so data is not collected
nor sent during power failures. When power supply resumes how-
ever, the device assumes all prior settings and starts collecting and
sending data without any need for user intervention.
For mobile data network failures, the device has a built-in local
buffer for keeping collected data stored for later transmission. The
buffer capacity is 3250 data series, each consisting of 250 Modbus
registers. With a 15 min update interval, the buffer can store up to
one month’s data. When the GSM network resumes service, all
buffered data is sent to the server without any need for user inter-
vention.

7 Warranty
ionSign grants a warranty of two (2) years for all delivered devices and
software services. The warranty starts on the date of the delivery and it
covers material and manufacturing defects. The warranty does not cover
defects caused by improper use or installation nor does it cover defects
caused by factors out of ionSign’s control. These would be for instance grid
malfunction or service changes of network operators services. ionSign deliv-
ers a new device to replace the defected one, without cost. Alternatively,
ionSign may repair the defected device. The defected device must be re-
turned to ionSign, if required, at ionSign’s cost. The warranty does not cover
dismantling, installation, and introduction costs and the like. ionSign warrants
that the provided software essentially manage with their designed tasks, at
the time of delivery. All significant software defects are covered by the war-
ranty. The defects will be resolved without unnecessary delay. The resolution
may be an instruction to circumvent the defect. If the delivery includes third
party products or services, these are only covered by the applicable warranty
provided by that third party. Title to the delivered goods transfers to the client,
when the invoiced price is paid in full. All immaterial rights related to devices
and services remain the property of ionSign. If the service was a design
assignment, the client assumes the right to use and further develop the
assignment results. ionSign is eligible to use the client’s name as a reference
in its marketing. ionSign is not eligible to disclose the order details without
prior consent. In case of a force majeure, preventing to act according to the
purchase agreement, the affected party will start immediate negotiations to
assess the effects of the obstacle on the scope and schedule of the purchase
agreement. ionSign appropriately backs up client’s data residing on its serv-
ers. In spite of this, ionSign assumes no responsibility of possible damage
due to loss of data. ionSign assumes no responsibility of direct or indirect
damage to property or people, nor work or travel expenses, caused by using
its services or devices, unless due to gross negligence. ionSign’s financial
liability is always limited to the value of the delivered goods and services,
unless otherwise inflicted by the Finnish law.
