7bit Synapse User manual

Synapse
MQTT/Modbus TCP/8DI/8DO(R)/32x1-Wire/AC
Industrial digital input/output modulefor
remote processcontrol and data acquisition
Thank you for choosing our product. The 7bit Synapse module designed as a remote
Ethernet DIO, counter and 1-Wire temperature input module for industrial
automation and monitoring applications. MQTT connectivity option allows you to
create cloud-based monitoring & control applications. Built-in AC power supply and
2-port Ethernet switch simplify installation and cabling, extending network length and
allowing to install the module into existing network w/o extra equipment. The setup
is made easy with the web-config page.
Module Synapse is an OPEN-TYPE device. It should be installed in a control
cabinet free of airborne dust, humidity, electric shock and vibration
The device is operating at dangerous voltage rating. High voltage also may
occur at output terminals during it work. Please do not touch these
terminals when the device is powered on. DO NOT connect AC power to any
of input terminals, otherwise serious damage may occur. Please double
check all wiring before Synapse is getting powered up
The following abbreviations are used for Modbus registers functions: C -
Coils, DI - Digital Inputs, HR/IR –Holding/Input Registers, and their data
format: W - Word (2 bytes), DW - Double Word, b –bit. R/W –Read/Write
mode.

3. Wiring
3.1 Ethernet. Synapse has an embedded switch which make easy toconnect numerous
modules simply, connecting them to each other in "daisy chain". As it is true Ethernet
witch, each connection may be up to 100 m. It is also possible to connect the device
at any breaking of existing Ethernet link.
3.2 Digital inputs
Use internal power supply for powering inputs via long cables with caution
due to low voltage and voltage drop you may have unstable DI signaling
3.3 Digital outputs There are 2 groups by 4 outputs, each can be either relay or SSR
(by order) type. Due to Zero-cross detection unit, SSR provides comfort switching for
any AC load in the range 85 - 220V, 2A. Relay outputs is commonly used for dry
contacts and DC signals commutation.
To avoid sparks, limit switching currents and increase switching lifetime for
the outputs, it is strongly recommended to use extra snubber circuits for
inductive loads.
3.4 Safe power on After power on the module can restore its outputs to a previous
state. For many applications it is convenient feature, but for some not. E.g. some parts
of a heavy machine may accidentally move on repower and cause dangerous situation.
To avoid this problem now there is a special setting to choose output state after
repower:
Address
Description
Data
R/W
Default
HR35
Safety state 0 –off, 1 - on
W
R/W
0 (off)
3.5 PWM for triac outputs The duty cycle is set as 0 .. 100 which means how many
periods of AC current from one hundred will power the load. So the time base of the
PWM is 100 * 20 ms (1/50Hz) = 2 seconds. Before using DO for common ON –OFF
control set PWM values to 0.

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-Wirebus 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.
