5.3 Activation and registry
When using the UNICOM 300 as data logger, it is necessary to carry out the following action with the
central acquisition system:
The modem is activated when it is supplied with power (230 VAC / 24 VDC).
The modem can also be activated by pressing SW1 for 4 seconds until the NETWORK status LED
lights up (see figure 3). The UNICOM 300 will now log on. Registration can take several minutes. If
UNICOM 300 is successfully logged on to the network, the network status LED (Table 4) will flash. If
TCP is active, the WDS status LED will be active.
Let the central acquisition system connect to UNICOM 300 and synchronize the clock. This ensures that
the internal clock is synchronized with the central acquisition system. Wigersma & Sikkema delivers
UNICOM 300 standard with deactivated data logger and modem functions. Clock synchronization will
activate the datalogger functions (the scheduler, interval logger, the historical logger and, if activated,
the FTP). If UNICOM 300 is configured for encoder readout, an encoder initialization will also take place
with the data from the gas meter being read out.
5.4 Device init function
The device init function is used for synchronizing the clock with an NTP server, sending a first FTP
message and deactivating the stock lock function after installation of the UNICOM 300.
To activate the device init function, press switch SW1 until status LED INIT flashes once every 4
seconds. Then release SW1.
The device init function can only be activated if NTP, FTP and the APN are programmed.
If they are not programmed, the function cannot be activated, and the status LED INIT will flash 1x per
second when pressing switch SW1.
The initialization then starts, and the current date, time and modem information are requested.
The stock lock of UNICOM 300 is also deactivated. The meter (UNIGAS 300 or UNICOM 300) will then
handle the further device init. If the UNICOM 300 is set as Encoder, the encoder initialization will also be
carried out. When the encoder initialization is complete, the status LED INIT will flash once every 2
seconds.
Next, an FTP message will be sent, and after sending the first FTP message, the status LED INIT will
be on continuously for 10 seconds to indicate that the device init has been completed correctly.
If the device init is not to be executed, the user must release SW1 within 4 seconds.
5.5 Adaptation of use: data logger <-> transparent modem
Adaptation of use as a data logger to use as a transparent modem:
•
Check with UNITOOL whether value C.93.15 is "off" or set the value C.93.15 to "off".
•
Activate the stock lock function, see table 3.
Adaptation of use as a transparent modem to data logger:
•
Check with UNITOOL whether value C.93.15 is set to "on" or set the value C.93.15 to "on".
•
This is done automatically with a clock synchronization by the central acquisition system or when
a device init is executed (see chapter 5.4).
5.6 Out of service
If it is necessary to deactivate the UNICOM 300 (take it out of service), it
must
be ensured that the
modem is
not active
!
This can be checked by activating SW1 for 1 second (see table 3, from firmware version 11.0.21)
or activating the communication port SW2 which causes the status LED to display.
LED "Network" must be
off
, see also Table 4.
