MODES OF COMMUNICATION
Modbus TCP: Modbus TCP protocol enables to read measured values.
Telnet: Port 9999 enables to set alarm limits (lower, upper limits, hysteresis for temperature and time delay), e-mail addresses, SNMP addresses, probe description, refresh of www pages (10s to 65535s), set storing interval to history (10s to 65535s), enable each communication channel. Capacity of the history memory is 600 values. Password protection of this port is enabled. Automatic IP address assignment from DHCP server is also enabled.
WWW pages: User selectable design of www pages enabling to display curve of measurement history. User can design the look of www pages and temperature history.

from similar Comet internet www sensor T7511
SNMP: It is possible to read actual values and alarm limits. In case of alarm creation warning message (trap) is sent to addresses defined by the user (maximum three addresses).
SOAP: Online transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s.
Online thermometer enables to monitor measured values. In case of exceeding of adjusted limits warning message can be sent to specified addresses.
There are the following options of alarm indication:
ALARM INDICATION OPTIONS
E-mail: In case of alarm creation warning e-mail message is sent to addresses defined by the user (maximum three addresses) or via e-mail to SMS message.
SNMP: In case of exceeding of adjusted temperature limits alarm is activated and warning trap is sent to user specified IP addresses (maximum 3 addresses).
WWW pages: In case of exceeding of adjusted temperature limits active alarm is displayed on www page.
syslog: Online thermometer enables to send text messages to selected syslog server after different events appear.
Synchronizing of time and record to www table and temperature history is enabled by SNTP via Internet.

Included accessory:

Traceable calibration certificate from the manufacturer, instruction manual. Calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
Example of calibration certificate.

TSensor - freeware for online configuring of the transmitter is ready to download.

SensorReader - freeware for online logging values from one transmitter to a PC disk file is ready to download. Program enables to alarm acoustically the PC user if adjusted alarm limits are exceeded. Recorded values in CSV format are easy to process in e.g. Excel. Program can be started several times on a computer at the same time to monitor values from several transmitters. For acquiring values from several transmitters, also third party software is possible to use. Tested functionality is with programs:

LabVIEW from National Instruments, by means of the free Modbus Library for LabVIEW. For viewing of actual values and graphs following examples of application were created in LabVIEW 8.5 :
P851x-Ethernet.vi for single channel thermometers P8510, P8511
P8541-Ethernet.vi for quad channel thermometers P8541

TIRS.NET - transmitters are also directly supported by program TIRS.NET from Coral s.r.o. company. Please download demo enabling full work with transmitters.

Tested functionality is also with programs:
Advanced Host Monitor, ControlWeb, EasyView.

For record of values to graphs via web interface, project Cacti www.cacti.net is available.

OPTIONAL ACCESSORY
DBS Sensor Monitor DBS Database program DBS Sensor Monitor for online data acquisition and analysis from Comet sensors. It contains all necessary components for monitoring of sensors, including one licence of DBV Database Viewer.
