Introduction
This chapter provides basic information about device. Before starting, please
read this manual carefully.
Web Sensors P8552, P8652 and P8653 are designed to measure temperature or
relative humidity up to two external probes. This allows to measure values
from two different places by one device. Temperature can be displayed in °C or
°F. Relative humidity have unit %RH.
Devices are equipped by three binary inputs. P8552 and P8652 are quipped by
three binary inputs to get state from dry contacts or binary sensors with
voltage output. Type of the binary input is selectable in device setup. P8653
have dedicated first binary input for connection of flood detector LD-81. This
detector is part of the shipment. Other two binary inputs can be used to
connection of dry contacts or binary sensors with voltage output. Type of
these two binary inputs is selectable at device setup.
Communication with the device is realized via Ethernet network. Devices P8652
and P8653 can be powered from external power supply adapter or by using power
over Ethernet – PoE.
Web Sensor P8552 supports powering from adapter only.

- sensors with two state output to connection into binary inputs of Web Sensor (dry contacts or voltage contacts)
- for P8653 device flood detector LD-81 which is part of shipment
Mounting the device
-
check if the equipment from previous chapter is available
-
install the latest version of TSensor software. This software will help you find device on network and to change IP address of the device. Device configuration is made using web interface. TSensor software can be free downloaded from the manufacturer’s website. Due to reducing impact to environment is CD not part of shipment.
-
contact your network administrator to obtain following information for the connection to the network:
IPv4 address:…………………………
Gateway:………………………………
DNS server IP:…………………………..
Netmask:…………………………………. -
check if there is no IP address conflict when you connect the device into network for the first time. The device has from factory set the IP address to 192.168.1.213. This address must be changed according to information from the previous step. When you are installing several new devices, connect them to the network one after another.
-
connect temperature and humidity probes to Web Sensor
-
connect binary inputs of the device, for device P8653 connect flood detector LD-81 at the first binary input (BIN1)
-
connect the Ethernet connector
-
if the power over Ethernet (PoE) is not used, connect the power adapter 5V/250mA
-

Device settings
-
run configuration software TSensor on your PC
-
switch to an Ethernet communication interface
-
press button Find device…
-
the window shows all available devices on your network
click to Change IP address to set new address according to network administrator instructions. If your device is not listed, then click Help! My device wasn’t found! Then follow the instructions. MAC address is on product label. The device is factory set to IP 192.168.1.213. -
gateway may not be entered if you want to use the device only in local network. If you set the same IP address which is already used, the device will not work correctly and there will be collisions on the network. If the device detects a collision of IP address, then reboot is performed automatically.
-
after changing IP address device is restarted and new IP address is assigned.
Restart of the device takes about 10 seconds. -
find the connected probes and change binary input type on webpages of by TSensor, if necessary
Checking functions
The last step is to check measured values on the device website. Enter the
device IP address into address bar of the web browser. If the default IP
address was not changed, then insert http://192.168.1.213.
Displayed web page lists actual measured values. If the web pages are
disabled, you can see text Access denied. If the measured value exceeds the
measurement range or probe is not correctly installed, then is shown Error
message. If the channel is switched off, the web site displayed n/a instead of
the value.
Device setup
This chapter describes basic device configuration. There is a description of
settings using web interface.
Setup using web interface
Device can be setup using web interface or TSensor software. Web interface can
be managed by the web browser. Main page will be shown when you insert device
address into address bar of your web browser. There you find actual measured
values. Page with history graphs is shown when you click to tile with actual
values. Access to device setup is possible via tile Settings. 
General
Device name can be changed using item Device name. Measured values are stored
into memory according History storage interval field. After changing of this
interval all history values will be cleared. Changes must be confirmed by
Apply settings button. 
Network
Network parameters can be obtained automatically from DHCP server using option
Obtain an IP address automatically. Static IP address is configurable via
field IP address. It is not necessary setup Default gateway while you use
device inside one subnet only. DNS server IP is required to set for proper
function of DNS. Option Standard subnet mask sets network mask automatically
according to A, B or C network class. Subnet mask field must be set manually
when network with non-standard range is used. Periodic restart interval
enables to restart device after selected time since device start. 
Alarm
limits
For each measurement channel is possible to set upper and lower limits, time-
delay for alarm activation and hysteresis for alarm clearing. 
Example of
setting the limit to the upper alarm limit: 
In Point 1 the temperature exceeded the limit.
From this time, the time-delay is counting. Because at point 2 the temperature
dropped below the limit value before the time delay expired, alarm was not
set.
In Point 3 the temperature has risen over limit again. During the time-delay
the value does not drop below the set limit, and therefore was in Point 4
caused alarm. At this moment were sent e-mails, traps and set alarm flag on
website, SNMP and Modbus.
The alarm lasted up to Point 5, when the temperature dropped below the set
hysteresis (temperature limit – hysteresis). At this moment was active alarm
cleared and e-mail send.
When alarm occurs, alarm messages will be sent. In case of power failure or
device reset (e.g.
changing the configuration) will new alarm state evaluated and new alarm
messages will be send.
Channels
Channel can be enabled or disabled for measuring using item Enabled. Channel
can be renamed (max. 14 characters) and it is possible select unit of measured
value according to connected probe type. When channel is not used, it is
possible copy to it one of other channels – option Clone channel. This option
is not available at fully occupied device. Find sensors button starts
searching for connected probes. All changes must be confirmed using Apply
settings button. History values are cleared after changing of channel
settings. 
Binary inputs
Binary inputs can be enabled or disabled for states evaluation by the Enable
option. Name of the binary input is configurable (max. 14 characters). Closed
state description / High voltage description / Flood state allows to change
name of binary input in the closed state.
Open state has name according to Open state description / Low voltage
description / Dry state field. Alarm states are evaluated according set Time
delay for alarm. It can be selected that alarm is active at closed or open
state of binary input. Alarms on binary inputs can be disabled also.
Type of binary input is selectable – option Input type. Dry contact is a
default option and allows to use input with door contacts and sensors with
relay output. Voltage contact option can be used with sensors like an AC
detector SP008. Device P8653 have first binary input reserved for flood
detector LD-81. 
SOAP protocol
SOAP protocol can be enabled by option SOAP protocol enabled. Destination SOAP
server can be set via SOAP server address. For setup of server port can be
used option SOAP server port. Device sends SOAP message according selected
Sending interval.
Option Send SOAP message when alarm occurs sends message when an alarm on
channel occurs or alarm is cleared. These SOAP messages are sent
asynchronously to selected interval. 
Email
Email sending enabled option allows e-mail features. It is necessary set
address of the SMTP server into SMTP server address field. Domain name for
SMTP server can be used.
Default port of the SMTP server can be changed using item SMTP server port.
SMTP authentication can be enabled using SMTP authentication option. When
authentication is enabled Username and Password must be set.
For successfully e-mail sending it is necessary insert Email sender address.
This address is usually same as username of the SMTP authentication. Into
fields Recipient 1 to Recipient 3 it is possible set address of e-mail
recipients. Option Short email enable sending e-mails in short format. This
format is usable when you need to forward e-mails into SMS messages.
When option Alarm email repeat sending interval is enabled and there is active
alarm on channel, then e-mails with actual values are sent repeatedly. Info
email sending interval option enables sending e-mails at selected time
interval. CSV history file can be sent together with the repeat/info e-mails.
This feature can be enabled by Alarm and Info emails attachment option.
It is possible to test e-mail function using button Apply and test. This
button saves a new settings and sends a testing e-mail immediately. 
Modbus a
Syslog protocols
ModbusTCP and Syslog protocol settings are configurable via menu Protocols.
Modbus server is enabled by default. Deactivation is possible via Modbus
server enabled option. Modbus port can be changed via Modbus port field.
Syslog protocol can be enabled using item Syslog enabled. Syslog messages are
sent to IP address of the Syslog server – field Syslog server IP address.
SNMP
For reading values via SNMP it is necessary to know password – SNMP read
community. SNMP Trap can be delivered up to three IP address – IP address of
the Trap recipient.
SNMP Traps are sent at alarm or error state on the channel. Trap feature can
be enabled by option Trap enabled. 
Time
Time synchronization with SNTP server can be enabled by Time synchronization
enabled option. IP address of the SNTP is necessary to set into SNTP server IP
address item. List of free NTP servers is available at www.pool.ntp.org/en.
SNTP time is synchronized at UTC format, and due to be necessary set
corresponding time offset – GMT offset [min]. Time is synchronized every 24
hours by default. Option NTP synchronization every hour decreases this
synchronization interval to one hour. 
WWW and security
Security features can be enabled by the Security enabled option. When security
is enabled, it is necessary to set administrator password. This password will
be required for device settings. When secured access is required even to
actual values reading it is possible to enable User account only for viewing.
Port of the www server can be changed from the default value 80 using filed
WWW port. Web pages with actual values are refreshed according to Web refresh
interval field.
Memory for
minimal and maximal values
Minimal and maximal measured values are stored into the memory. This memory is
independent from values stored in history memory (charts). Memory for minimal
and maximal values is cleared in case of device restart or by the user
request. In case of device
time is synchronized with SNTP server, timestamps for minimal and maximal
values are available.
Backup and restore configuration
Device configuration can be saved into file and restored if needed. Compatible
parts of configuration can be uploaded into another device type. Configuration
can be moved only within devices at same family. It is not possible restore
configuration from p-line Web Sensor into t-line Web Sensor and conversely.
Setup using TSensor software
TSensor software is an alternative to the web configuration. Some less
important parameters are configurable by the TSensor software only.
Parameter MTU size can reduce size of the Ethernet frames. Lowering of this
size can solve some communication problems mainly when VPN is used. TSensor
software can set offset of values at temperature probes. At DSRH humidity
probes is possible set correction of the humidity and temperature.
Factory defaults
Factory defaults button set the device into factory configuration. Network
parameters (IP
address, Subnet mask, Gateway, DNS) are left without changes. 
Network parameters are changed when factory default
button is pressed during device power on (in more detail – see Chapter 5).

Communication protocols
Short introduction to communication protocols of the device. To use some
communication protocols is necessary software, which can use the protocol.
This software is not included. For detailed description of protocols and
application notes please contact your distributor.
Website
The device supports displaying of measured values, history graphs and
configuration using web browser. History graphs are based on HTML5 canvas. Web
browser must support this feature for proper function of graphs. Firefox,
Opera, Chrome, or Edge can be used. If the device has set IP address
192.168.1.213 type into your browser http://192.168.1.213. Automatic refresh
interval of the web pages can be changed from default value 10sec. Actual
measured values can be obtained using XML file values.xml and JSON file
values.json. Values from history can be exported in CSV format. Interval of
storing values into internal history memory is configurable also. History is
erased after every reboot of the device.
Reboot of the device is performed when the power supply is disconnected and
when configuration change.
SMTP – sending e-mails
When measured values are over the set limits, the device allows send e-mail to
a maximum of 3 addresses. E-mail is sent when alarm condition on the channel
is cleared or a measuring error occurs. It is possible to set repeat interval
for e-mail sending. For correct sending of e-mails it is necessary to set
address of SMTP server. Domain address can be used as SMTP server address too.
For proper function of DNS is required to set DNS server IP address.
SMTP authentication is supported but SSL/STARTTLS not. Standard SMTP port 25
is used by default. SMTP port can be changed. Contact your network
administrator to obtain configuration parameters of your SMTP server. E-mail
sent by the device cannot be
answered.

SOAP
The device allows you to send currently measured values via SOAP v1.1
protocol. The device sends values in XML format to the web server. The
advantage of this protocol is that communication is initialized by the device
side. Due to it is not necessary use port forwarding.
If the SOAP message cannot be delivered, warning message via SNMP Trap or
Syslog protocol is sent. The file with the XSD schema can be downloaded from:
http://cometsystem.cz/schemas/soapP8xxxBinIn.xsd. SOAP message example:
<?xml version=”1.0″ encoding=”utf-8″?>

The device allows time synchronization with NTP (SNTP) server. SNMP protocol
version 3.0 is supported (RFC1305). Time synchronization is made every 24
hours. Time synchronization every hour can be enabled. For time
synchronization it is necessary set IP
address to the SNTP server. It is also possible set GMT offset for correct
time zone. Time is used in graphs and history CSV files. Maximum jitter
between two time synchronization is 90sec at 24 hours interval.
