7.2.2.1.
Sensors ratio setup
The ratio between 1-Wire and MODBUS RTU sensors can be set here. By default, it is 4:4.
7.2.2.2.
1-Wire sensors setup
Detection is made either after power on or by the
button “Scan for new sensors”. All found
sensors are shown in ascending order refer their unique ID number.
It is possible to lock a 1-Wire sensor in a specific position. To do this all sensors should be
added one by one. After every addition, a new scan should be made and a newly found sensor
should be locked in its
position
. If a
ll sensors are locked, removing one “in the middle” will not
change the positions of other sensors after reset. This option is very useful when TCW210-TH
is used as a part of а monitoring and control system managed either by SNMP or HTTP API
commands.
7.2.2.3.
MODBUS RTU communication setup
TCW210-TH supports MODBUS RTU over RS-485 interface. All sensors connected to this
interface should work with the same communication settings.
By default, TCW210-TH works with the standard for MODBUS RTU settings
–
19200, E, 1.
In the right part of the section, there is a tool for scan the MODBUS RTU interface. To optimize
scan time, the appropriate address segment should be set up after this, the button “Save” on
the bottom of the page should be pressed.
7.2.2.4.
MODBUS RTU sensors
TCW210-TH supports Teracom and third-party MODBUS RTU sensors.
