GEKKO datalogger
About GEKKO
GEKKO datalogger has a robust industrial design.
GEKKO is designed for use in wastewater and water supply applications and can, by means of external
equipment, be used for H2S detection, level measurement, overflow recordings and the recording of
rainfall events.
GEKKO can communicate via standard MODBUS TCP/IP, SMS commands or SigFox IOT protocol.
Communication is via the built-in 4G or SigFox modem on its own PCB board. This allows for upgrading the
communication platform to future communication forms without replacing the entire data logger.
GEKKO has a USB interface for programming and downloading of data. GEKKO can gather and log various
types of data.
GEKKO is a Danish developed and produced product, and comply with all specifications for electronics
components, for installation in harsh environments.
AcowaCore
About AcowaCore
AcowaCore is a data processing program, used to collect data from both our SigFox based FireFly and our
4G and SigFox based GEKKO data loggers, and transform it into a standard ModBus protocol. This data can
hereby be returned directly to the user's own SCADA system, without any need for specified driver
configuration.
As something quite unique, AcowaCore can process event-based logging from our GEKKO datalogger and
return this data in a standard ModBus format that can be used in all SCADA systems. At the same time,
AcowaCore allows all data on stormflow installations, profiles and conditions to be processed directly in
AcowaCore. Therefore, the user only needs to make changes in the AcowaCore and not in the device itself.
What makes AcowaCore truly unique is the visualization platform AcowaDash. AcowaDash enables a
custom interface that is intuitive and easy to understand. The individual users can be divided into different
levels, so everyone is comfortable using AcowaDash.

AcowaZoo
Connecting to a PC
USB connection
GEKKO connects to the PC via a Micro-USB connector on the side of the device. The AcowaZoo will then
connect to the device for configuration. When the AcowaZoo program starts, it will continuously try to
establish contact with a GEKKO device via USB connection.
AcowaZoo Installation
Driver installation
Before installing AcowaZoo on a computer running Windows 7 or Windows 8, an additional driver file for
communication via the USB port must be installed.
Right-click on the file "fsl_ucwxp.inf" and select "install". Windows will ask for permission to install. The file
is located in the "driver" folder under the " AcowaZoo" folder.
Program installation
AcowaZoo can be installed on computers running Windows 7, 8, or 10 or newer. Run the program
"AcowaZooSetup.exe" ("AcowaZooSetup _32bit.exe" on 32-bit operating systems) and follow the on-
screen instructions:
Choose if you want to create a desktop shortcut
Then choose ”Next”
Choose ”Install”

Logs - Settings
This section describes the settings for the data logger's call and log
intervals.
GEKKO data logger has options for a standard logging as well as an intensified logging in case of an event.
Default log and call interval are always defined in the data logger.
Event based logging enables a differentiated log and call interval compared to the standard log and call
interval. It must be determined what starts the event-based log. This is done by selecting the desired option
under event signal. Typically, it will be either a limit value (AI1 - High limit) on the analog input or a
mechanical input (rocker or similar on DI3).

mA". Min./Max. scaling points is entered at the desired resolution. For example, if a pressure transmitter
with a measuring range of 0-5m is used, and you need to read the level in cm. Enter min. = 0 and max. =
500.

Limit relay values
Limit relay values can be configured for high/low limit levels. For both types of limits the function can be
activated/deactivated, and the limit relay can be named with a label used as text in an alarm list and in SMS
alerting.
Values can be set to which level the high/low limit relays are activated, and a delay can be attached, so that
a limit value must be exceeded for a given time before the signal is registered as active. It is possible to
choose whether to send the signal as an alarm or to act as a local alarm.
If an alarm (True overflow in progress) is desired, regarding the use of GEKKO for stormflow registrations,
the limit value is set with the same value as the value for the overflow edge. Furthermore, checkmark the
options "High limit relay in use" and in "Alarm at high limit in use".
Digital Input (I1-I4)
I1-2 input on the GEKKO logger can be used as either standard 0-10 V inputs, or standard DI where "0" <5V
and "1"> 12V.
DI3-4 is either standard DI where "0" <5V and "1"> 12V or pulse inputs.
The input functions can be set in AcowaZoo when I1-4 is
selected in the Settings selection. VI1-2 contains the
following settings:

To activate the Device settings, click on the following symbol:
This results in the following window.
Reports and alarms:
If the GEKKO is used as a stand-alone device that is not connected to a SCADA system via AcowaCore, it is
possible to receive a daily status SMS and alarm SMS in case of an alarms.
For daily status SMS, the following parameter must be used: "Daily status SMS in use" to activate the
function.
"Receivers Phone Number." There is only one user who can receive a status SMS.
"Time of day (in full hours)" you want a status SMS for example 9:00 pm. enter the value 9.
Alarms can be sent to 4 different recipients. You can use SMS or standard dial-up. You must enter a delay
between each alert in the list. For SMS, a typical delay of 60 sec. When using dial-up, it will typically be 300
seconds.
Reverse Comm (Rarely used):
Enter the IP address and TCP port of the server on which AcowaCore is installed. The GEKKO logger will
then be a TCP client and connect to the SCADA system via AcowaCore.
