Page 9
Pressing the “Start” button will start your web browser and display the Monitoring page of your
TCG120
controller.
7.1. Monitoring page
Monitoring page displays the current I/O state of
TCG120
controller
.
The page has 4 sections –
“Sensors”, “Digital inputs”, “Analog inputs” and “Relays”.
For every parameter (sensor, input, relay) there is a description of up to 20 characters. The default
descriptions can be changed in “Setup-Input/Output” menu.
The Monitoring page can be automatically refreshed on an interval of 0 to 254 seconds. Zero means
no automatic refresh. This parameter is set in section “Setup->System->Monitoring page automatic
refresh”. By default it is 30 seconds.
7.1.1. Sensors section
All detected 1-Wire sensors are shown in this section. Sensor detection is made either after
connecting the power supply or by “Scan for new sensors” button. All found sensors are shown in
ascending order refer their unique ID number. For every sensor there are description, value, and ID
information.
Teracom temperature sensors readings are shown in the Value 1 column. TSH2xx
temperature/humidity sensors have the 2nd parameter shown on the Value 2 column.
It is possible to lock sensors in a specific position. To do this all sensors should be added one by one.
After every addition new scan should be made and newly found sensor should be locked in its position.
If all sensors are locked, removing one “in the middle” will not change the positions of following sensors
after reset. This option is very useful when
TCG120
is used like a part of monitoring and control system
managed either by SNMP or HTTP API commands.
7.1.2. Digital inputs section
Digital inputs can be used for monitoring the state of discrete devices – motion sensor, door
contact, relay contact, alarm output etc. Both digital inputs are not galvanic isolated.
