The P8552 is designed for measurement of temperature, humidity and monitoring of 2 digital inputs. It is possible to read values from PC through the Ethernet connection. The following formats are supported:

www pages with user-design possibility
Modbus protocol
SNMPv1 protocol
SOAP

The instrument may send a warning message to several defined points if the measured value gets out of adjusted limits. There are the following possible ways to deliver the warning report:

to send an e-mail to maximum of three e-mail addresses
to send a SNMP trap to maximum of three IP addresses
to display an alarm state on the device www page
to send a message to Syslog server

Alarm limits may be set via the supplied TSensor program, Modbus or Telnet protocols. The alarm state may be read via the device www pages, Modbus or the SNMPv1 protocol. If channel isn’t wired, it is possible to turn off measured channel.

The P8552 has a built-in web server showing current values, alarm limits alarm state and recorded history in both tabular and chart formats. It can be viewed by any web browser. Measured value is in graph displayed by green colour, error or not yet measured values are displayed as grey broken line. Upper (lower) alarm value is in graph displayed as red (blue) line. If all values are over upper (lower) limit, the alarm line will be in the bottom (top) graph part displayed. It is possible export history to CSV file (comma or dot decimal separator) for import to Excel.

Example Pages >>

email

When temperature alarm limits are exceeded, an e-mail message is sent to addresses defined by the user (maximum three addresses). Maximum length of an e-mail address is 55 characters.

SNMP

By means of the SNMPv1 protocol it is possible to find currently measured values and parameters concerning alarms. In case of alarm activation, warning message (a trap) can be sent to specified addresses. By means of the SNMPv1 protocol it is also possible to display history of last 600 measured values.

MODBUS

The device contains support for the Modbus protocol to communicate with control systems. The protocol runs in the RTU mode.
