3.6 Predictive maintenance functions (changeover & time on counters)
Power on cycles and run hours may reduce life-time of the equipment under monitor.
Now it is possible to count them using Synapse onboard counters and totalizers:

3.7 1-Wire connection
The Synapse provides connection for up to 32 digital
temperature sensors DS18B20 via 1-Wire bus with a maximum length 200 m, as shown
at figure below.
Bus topology. Up to 200 meters.
Auto enumeration for 1-Wire sensors.
Each DS18B20 has their own unique serial
number. Using a special search algorithm, the Synapse finds and saves the
enumeration scheme for the sensors found in the static memory. New sensors still can
be added to the existing enumeration by:
▪
powering on or resetting the module
▪
writing non-zero value into HR33 register

4. Configuration
The factory network default settings for the Ethernet interfaces is a DHCP client. So,
after power on and plugging it into your router network it automatically will be added
to your network. You may setup a static DHCP lease for the module, or use manual IP
network setup.
4.1 Configuration mode for IP settings
When you have a device with unknown
address and want to make quick IP setup, switch the module to the CONFIGURATOIN
MODE. Hold the reset button during reboot for a few seconds (status LED will be
blinking frequently). The module will start with
192.168.4.1
address. In this mode you
can change setting either with
Configuration
Web server
or with
Modbus setting
registers.
To switch back to normal mode, reboot the module.
4.2 Configuration Web server
In the configuration mode, there is Configuration
web-page available on the
192.168.4.1
. Instead of Modbus register, you can use this
page for module setup. The page can be switched off during setup. To enable it again ,
use the following register:

5. Diagnostics
The normal LED state upon power on is as follows:
▪
red POWER - always on.
▪
green SYSTEM
–
is blinking once a second (two times faster in configuration
mode)
▪
yellow 1WIRE
–
blinks when the sensors are polled
The DI/DO LEDs reflects the actual signal states on terminals. During normal boot
process, DI/DO ticks in series.
Use
“ping” command to
check network connection and Modbus/MQTT testing tools
to test the protocol connection.
In case of troubles with adding temperature sensors, the most probable cause is the
length of 1-Wire bus or its topology (signal or power attenuation, caused too long line,
interference due to side branches etc.). First of all, try to connect sensors with short
wires. If ok, then check wiring (refer to general Maxim 1-Wire recommendations).
Synapse has internal watchdog, which may reboot the device in case of accidental
malfunction. Refer to the following diagnostic registers to check if failures might have
occurred.
In a case the device doesn't working properly, please contact to your supplier.
