PST-P8511

 Low Cost Intelligent Ethernet Thermometer

Ethernet thermometer is designed for ambient temperature measurement and measurement from up to four external temperature cable probes. Measurement in degrees Celsius and degrees Fahrenheit supported. Ethernet thermometer is built in a durable plastic case.

APPLICATIONS - measuring and control of air humidity at:

• server rooms

• telecommunication devices

• warehouses

• glasshouses

• manufacturers

• museums, archives, galleries

• air-conditioned rooms

Modes of communication

Modbus TCP

Modbus TCP protocol enables to read measured values, set alarm limits, adjust the probe.

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 100 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.

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

Transmitter enables to send actual measured data in the format of SOAP message to selected web server in preset interval 10-65535 s. In case message is not received by the server till next message is sent, warning trap 1/2 is sent.

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).

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

Transmitter enables to send text messages to selected syslog server after different events appear. E.g. after transmitter restart, alarm activation, communication error with SNTP, write to transmitter via mdb, sntp, after firmware change, after alarm termination, after communication error with SOAP server.
