Features

  • Superior technology
  • Wireless data transfer
  • Excellent memory space

Alarm and Fault Notifications

Fault Notification
Automatic generation and dispatch of more than 100 fault notifications
Condition based monitoring of data may launch events
Message templates may include current values from PLC or Tixi Data Gateway
Up to 100 predefined events may trigger actions.
Alarm Cascade

Message confirmation may be implemented by means of freely definable alarm levels.

Address Book
Address book with more than 100 contacts
Message Templates
More than 100 message templates may contain variable values from PLCs or the Tixi Data Gateway.
Destination addresses and PLC variables are defined as references.
Message length is not restricted (only by memory size).
Neutral Data
Data Converter
All data of local systems connected to the device (PLCs, meters, sensors etc) are managed by means of a
neutral variable table (XML). These XML-data are independent of their origin.
All Tixi functions use these neutral data.
Local PLC data may thus be translated from one system to another, e.g. meter data may be handed to a
PLC or BMS (building management system).
Data Logger
Data Logging

All values (e.g. PLC or meter values) may be logged on a regular basis.
(e.g. every 1 min, 15 min, 1h, 1d, ) or upon certain events.
Data is automatically compressed (binary format).

Data Dispatch
Saved Log data may be sent as E-Mail attachments at scheduled times or as a result of any event. Their
format is to be freely defined, such as XML or Microsoft Excel CSV.
Embedded Webserver
Webserver
The user may create custom websites with any HTML editor, including XML placeholders for system values.
By means of these websites, current data may be displayed or custom input masks can be defined.
Common Gateway Interface (CGI) for dynamic read and write of values and for log data readout.
Special SSI (Server side Includes) allow embedding of values and log data into websites.
Remote Control
Switching Commands
Switching commands may be transmitted via E-Mail, HTTP or TiXML command onto the Tixi Data Gateway.
HTTP and TiXML commands may be defined freely and may contain e.g. setpoint values.
Confirmation
If need be, the device may send confirmation commands upon receipt and execution of a remote switching
command, in order to report the positive (or negative) result of such.
Programmable Features
Scheduler
Event Calendar may trigger the following actions:
- Creation of logfile entries or dispatch of logfiles,
- Switching I/Os or setting PLC variables,
- Dispatch of periodic status messages
- Automatic shift schedules may change the receiver of messages.
Logical Operations
Functions (e.g. AND, OR, XOR, NOT) and
Comparisons (z.B. GT, LT, EQ) can be applied to variable values,
even along with time schedules, may trigger actions.
Sequencer
Time-dependent data arrays can be preset over a specific span of time, either via configuration or by
message. E.g monitoring of current values and dispatch of messages in case that current values exceed
min./max. curves (depending on a time grid of 15-min-steps up to one year).
Several curve sets may be used in conjunction or as separate data sets.
Arithmetic Operations
Simple arithmetics (ADD, SUB, MUL, DIV) allows calculation with PLC and variable values.
